This book describes for first time the synthesis and intensified process design in the production of top biofuels. The production of biofuels is not new. In 2019, global biofuel production levels reached 1,841 thousand barrels of oil equivalent per day, in stark comparison to the 187 thousand barrels of oil equivalent per day that was produced in 2000. Growth has largely been driven by policies that encourage the use and production of biofuels due to the perception that it could provide energy security and reduce greenhouse gas emissions in relevant sectors. From a technical point of view, almost all fuels from fossil resources could be substituted by their bio-based counterparts. However, the cost of bio-based production in many cases exceeds the cost of petrochemical production. Also, biofuels must be proven to perform at least as good as the petrochemical equivalent they are substituting and to have a lower environmental impact. The low price of crude oil acted as a barrier to biofuels production and producers focussed on the specific attributes of biofuels such as their complex structure to justify production costs. Also, the consumer demand for environmentally friendly products, population growth and limited supplies of non-renewable resources has now opened new windows of opportunity for biofuels. The industry is increasingly viewing chemical production from renewable resources as an attractive area for investment. This book uniquely introduces the application of new process intensification techniques that will allow the generation of clean, efficient and economical processes for biofuels in a competitive way in the market.

The present monograph is devoted to the chemistry of nitroazoles, one of the most interesting series of heteroaromatic compounds. The azoles hold a special position in the chemistry of heterocycles. Their unique properties and specific biological activity attract much attention of research chemists all over the world. During the last years the interest in the chemistry of nitroazoles has increasing. The nitro derivatives of azoles have found a wide application in various fields of industrial chemistry, agriculture, and medicine. Medical products developed by nitroazoles incluce a- mycin, metronidazole, misonidazole, tinidazole, nitazole, etc. , ionic liquids, hi- energy materials, synthons for nanocompounds, universal bases in peptide nucleic acids, plant growth regulators, and intermediates for organic synthesis. The investigations in the field of energetic compounds have received enormous interest in recent years. Energetic materials on the base nitroazoles - explosives, propellants, and pyrotechnics - are widely used for both civilian and military applications. Nitroazoles, especially polynitroazoles, possess higher heat of for- tion, density, and oxygen balance than their carbocyclic analogs. A number of ongoing research programs worldwide are aimed for the development of new explosives and propellants with higher performance characteristics or enhanced insensitivity to thermal or shock insults and pyrotechnics with reduced smoke. The preparation of nitroazoles demonstrates its great synthetic potential. At the same time, feasibility and availability of the starting molecules make this strategy a p- erful method for high-energy material construction.

Membranes are an energy efficient separation technology that are now the basis for many water treatment and food processing applications. However, there is the potential to improve the operating performance of these separations and to extend the application of membranes to energy production, gas separations, organic solvent-based separations, and biomedical applications through novel membrane materials. This book contains 20 chapters written by leading academic researchers on membrane fabrication and modification techniques and provides a comprehensive overview on the recent developments of membrane technology. Membranes can be manufactured from a range of materials including polymeric compounds, and ceramic materials, and both these materials are considered in the book. There are 5 chapters on water and wastewater membranes that cover the fabrication of thin film (TFC) composite membranes for nanofiltration(NF)/reverse osmosis (RO)/forward osmosis (FO) applications, stimuli responsive membranes, electrospun membranes, porous ceramic membranes, and polymeric ultrafiltration (UF) manufacture and modification. There are another 6 chapters on gas separation that consider carbon membranes, zeolite membranes, silica template and metal oxide silica membranes, TFC membranes, silica membranes, and metal organic framework (MOF) membranes. Zeolite membranes are also considered for organic solvent applications, as are solvent-resistant membranes manufactured by phase inversion, ceramic-supported composite membranes, and ceramic NF membranes. The emerging areas of membranes for energy and biomedical applications have 3 and 2 chapters, respectively. Energy applications consider ion exchange membranes for use in fuel cells, membranes for electrodialysis, and membranes for use in microbial fuel cells. For biomedical applications the chapters focus on hemodialysis membranes and redox responsive membranes.

Electrolyte solutions play a key role in traditional chemical industry processes as well as other sciences such as hydrometallurgy, geochemistry, and crystal chemistry. Knowledge of electrolyte solutions is also key in oil and gas exploration and production, as well as many other environmental engineering endeavors. Until recently, a gap existed between the electrolyte solution theory dedicated to diluted solutions, and the theory, practice, and technology involving concentrated solutions. Electrolytes: Supramolecular Interactions and Non-Equilibrium Phenomena in Concentrated Solutions addresses concentrated electrolyte solutions and the theory of structure formation, super and supramolecular interactions, and other physical processes with these solutions-now feasible due to new precision measurement techniques and experimental data that have become available. The first part of the book covers the electrolyte solution in its stationary state-electrostatic, and various ion-dipole, dipole-dipole, and mutual repulsion interactions. The second part covers the electrolyte solution in its nonstationary status, in the case of forced movement between two plates-electrical conductivity, viscosity, and diffusion. This theoretical framework allows for the determination of activity coefficients of concentrated electrolyte solutions, which play a key role in many aspects of electrochemistry and for developing novel advanced processes in inorganic chemical plants.

Salient points have been presented in as simple a manner as possible, while detailed examination of specific points of the theory has been left to those whose qualifications and interests better fit them for such tasks. In this volume, I have compiled basic formulations of many types of emulsion. This compilation is intended to provide graphic illustration of the breadth of emulsion technology. The formulations can also provide a starting point for the development of new and improved emulsion products and represent the types of product that can be made and their major constituents. These formulations are provided by manufacturers to illustrate the use of their products. The suitability of any product for marketing, or the determination of the patent position regarding any formulation, is the responsibility of the person who manufactures and/or sells the product. Many firms have generously provided formulation suggestions, and they merit my sincere appreciation for their help. Their contributions are acknowledged by appropriate references at the end of each chapter.
