Solid biofuels, in different trading forms, constitute an integral component of the energy mix of almost all developed and developing countries. Either in the form of pellets, briquettes, chips, firewood, or even as raw feedstock, solid biofuels are used mainly in the heating and power sector. Numerous sustainability concerns, focusing on the environmental, economic and technical aspects of solid biofuels exploitation, led to considerable advances in the recent years in this field. These developments mainly focus on the pre-treatment processes of the solid biomass to biofuels chain, the minimum requirements of the produced solid biofuels, as well as the efficiency and the environmental performance of their thermochemical conversion routes. This work aspires to provide the state of the art in the field of the exploitation of solid biofuels to present the main advances as well as the major challenges of this scientific fields. The topics presented in this book were examined and dealt with by the authors in the past few years, in numerous research projects and scientific publications. This book compiles all the assembled experience of the past few years, and aims to provide an overview of the solid biofuels exploitation field. Presents the latest standards and considerations on solid biofuels technical requirements; Contains numerous examples on applications in the field of solid biofuels thermochemical conversion, as well as the state of the art in this field; Includes sustainability aspects, including life cycle assessment aspects and financial concerns for the exploitation of solid biofuels.
In this book, a new approach to the theory and practice of two-phase systems based on a global invariant - entropy, - and other invariants is formulated and experimentally confirmed.
This book offers an overview of the state of the art in the field
of DeNOx catalysis in order to focus novel orientations, new
technological developments, from laboratory to industrial scale. A
particular attention has been paid towards the implementation of
catalytic processes for minimising NOx emissions either from
stationary or mobile sources under lean condition to meet future
standard regulations of NOx emissions. In the first part of this
book, critical aspects reported in the literature which usually
make difficult the achievement of efficient catalytic technologies
in those conditions are summarised and analysed in order two
separate new perspectives. The second part deals with fundamental
aspects at molecular level. A better understanding of the reactions
involved under unsteady-state conditions is probably a
pre-requisite step for improving the performances of the actual
processes or developing original ones. The development of powerful
in situ spectroscopic techniques is of fundamental interest for
kinetic modelling. Correlations between spectroscopic and kinetic
data with those obtained from theoretical calculations are
reported. Some illustrations emphasise the fact that these
comparisons may help in determining the nature of the catalytic
active sites and building predictive tools for simulations under
running conditions. The latter part of this book will be
illustrated by different practical approaches covering various
aspects related to the catalysts preparation and the development of
alternative technologies which include industrial considerations.
There is hardly any technical library in the world in which the volumes of the Chemical Formulary (Volumes 1-34) do not occupy a prominent place. Chemists both experienced and beginner, continually refer to them. It does not duplicate any of the formulas included in previous volumes, but lists a wide array of modern and salable products from all branches of the chemical industries. An excellent reference for formulation problems. -CONTENTS - I. Introduction - II. Adhesives - III. Beverages and Foods - IV. Cosmetics - V. Coatings - VI. Detergents and Disinfectants - VII. Drug Products - VIII. Elastomers, Plastics, and Resins - IX. Metals - X. Polishes - XI. Textile Specialties - XII. Miscellaneous - Appendix - Index - PREFACE - Chemistry, as taught in our schools and colleges, concerns chiefly synthesis, analysis, and engineering-and properly so. It is part of the right foundation for the education of the chemist. Many a chemist entering an Industry soon finds that most of the products manufactured by his concern are not synthetic or definite complex compounds, but are mixtures, blends, or highly complex compounds of which he knows little or nothing. The literature in this field, if any, may be meager, scattered, or obsolete. Even chemists with years of experience In one or more Industries spend considerable time and effort in acquainting themselves with any new field which they may enter. Consulting chemists similarly have to solve problems brought to them from industries foreign to them. There was a definite need for an up-to-date compilation of formulae for chemical compounding and treatment. Since the fields to be covered are many and varied, an editorial board of chemists and engineers engaged in many industries was formed. Many publications, laboratories, manufacturing firms, and Individuals have been consulted to obtain the latest and best information. It is felt that the formulas given in this volume will save chemists and allied workers much time and effort. Manufacturers and sellers of chemicals will find, In these formulae, new uses for their products. Non-chemical executives, professional men, and Interested laymen will make through this volume a "speaking acquaintance" with products which they may be using, trying or selling. It often happens that two Individuals using the same Ingredients in the same formula get different results. This may be due to slight deviations in the raw materials or unfamiliarity with the intricacies of a new technique. Accordingly, repeated experiments may be necessary to get the best results. Although many of the formulas given are being used commercially, many have been taken from the literature and may be subject to various errors and omissions. This should be taken into consideration. Wherever possible, it is advisable to consult with other chemists or technical workers regarding commercial production.

Most previous books have touched only lightly on the atom itself, but my experience in teaching engineers in the University of Manchester suggests that a greater depth of approach is welcome, perhaps because it can account for so much of the subsequent behaviour of metals.
Although many papers have been published describing methods for the inorganic analysis of petroleum no book has previously appeared devoted exclusively to this subject. The purpose of this work is to provide a laboratory handbook for industrial analysts of various degrees of professional training covering the determination of those elements commonly occurring in various types of petroleum products. The procedures represent, from the author's point of view, a reasonable compromise among the usual conflicting interests of speed, accuracy, and cost, and emphasize manufacturing rather than research applications.

As synthetic rubbers are now being made in this country and will play an important part in the future of the rubber industry, most of this book is devoted to them. How they are made and how they compare with natural rubber is discussed in the appropriate place.- To enable a reasonable comparison to be made between natural rubber and the various synthetic rubbers the subject has been treated from a scientific standpoint, and to keep the size of the book between reasonable limits much technological information has been omitted. Because of the comparison between natural and synthetic rubbers the first section of this book is devoted to natural rubber. In this section the fundamentals of rubber science are introduced, to be developed later in connection with the synthetic rubbers. This book is intended as an introduction to a complex subject, and as a surveyor report for non-technical readers who wish to know something about rubber. The reader who requires further information on a particular point or topic should consult the bibliography at the end of the book.-
The capability to generate potable water from polluted sources is growing in importance as pharmaceuticals, microplastics and waste permeate our soil. Nanotechnology allows for improvements in water remediation technologies by taking advantage of the unique properties of materials at this small scale.

The Fast Pyrolysis Handbook Volume 2 is an edited version of the final report of the European Commission and IEA Bioenergy sponsored Pyrolysis Network that officially finished in 2001. It provides a companion volume to the first handbook published in 1999 and it is again intended that this will provide a useful guide both to newcomers to the subject area as well as those already involved in research, development and implementation. A significant feature of this second volume is the greater attention paid to addressing commercial issues such as marketability, transportation and safety. Fast pyrolysis is a high temperature process in which biomass is rapidly heated in the absence of oxygen. As a result it decomposes to generate mostly vapours and aerosols and some charcoal. After cooling and condensation, a dark brown mobile liquid is formed which has a heating value about half that of conventional fuel oil. While it is related to the traditional pyrolysis processes for making charcoal, fast pyrolysis is an advanced process that is carefully controlled to give high yields of liquid. The essential features of a fast pyrolysis process are: very high heating and heat transfer rates, which usually requires a finely ground biomass feed; carefully controlled pyrolysis reaction temperature of around 500C in the vapour phase, with short vapour residence times of typically less than 2 seconds; rapid cooling of the pyrolysis vapours to give the main product - bio-oil. |
