Biochemical Engineering and Biotechnology, 2nd Edition, outlines
the principles of biochemical processes and explains their use in
the manufacturing of every day products. The author uses a diirect
approach that should be very useful for students in following the
concepts and practical applications. This book is unique in having
many solved problems, case studies, examples and demonstrations of
detailed experiments, with simple design equations and required
calculations.
The book provides the most up-to-date information on testing and
development of hydroprocessing catalysts with the aim to improve
performance of the conventional and modified catalysts as well as
to develop novel catalytic formulations. Besides diverse chemical
composition, special attention is devoted to pore size and pore
volume distribution of the catalysts. Properties of the catalysts
are discussed in terms of their suitability for upgrading heavy
feeds. For this purpose atmospheric residue was chosen as the base
for defining other heavy feeds which comprise vacuum gas oil,
deasphalted oil and vacuum residues in addition to topped heavy
crude and bitumen. Attention is paid to deactivation with the aim
to extent catalyst life during the operation. Into consideration is
taken the loss of activity due to fouling, metal deposition, coke
formed as the result of chemical reaction and poisoning by nitrogen
bases. Mathematical models were reviewed focussing on those which
can simulate performance of the commercial operations.
Configurations of hydroprocessing reactors were compared in terms
of their capability to upgrade various heavy feeds providing that a
suitable catalyst was selected. Strategies for regeneration,
utilization and disposal of spent hydroprocesing catalysts were
evaluated. Potential of the non-conventional hydroprocessing
involving soluble/dispersed catalysts and biocatalysts in
comparison with conventional methods were assessed to identify
issues which prevent commercial utilization of the former. A
separate chapter is devoted to catalytic dewaxing because the
structure of dewaxing catalysts is rather different than that of
hydroprocessing catalysts, i.e., the objective of catalytic
dewaxing is different than that of the conventional
hydroprocessing, The relevant information in the scientific
literature is complemented with the Patent literature covering the
development of catalysts and novel reactor configurations.
Separate chapter was added to distinguish upgrading capabilities of
the residues catalytic cracking processes from those employing
hydroprocessing. Upper limits on the content of carbon residue and
metals in the feeds which can still be upgraded by the former
processes differ markedly from those in the feeds which can be
upgraded by hydroprocessing. It is necessary that the costs of
modifications of catalytic cracking processes to accommodate
heavier feeds are compared with that of hydroprocessing methods.
Objective of the short chapter on upgrading by carbon rejecting
processes was to identify limits of contaminants in heavy feeds
beyond which catalytic upgrading via hydroprocessing becomes
uneconomical because of the costs of catalyst inventory and that of
reactors and equipment.

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.
The book gives a complete overview on today's research, development
and industrialization of fine chemicals from acetylene. The author
provides a comprehensive methodology by covering derivatives from
acetylene reacting with formaldehyde, alcohol, ketone, halogen and
acetic acid. The book offers extensive and practical reference work
for chemists and chemical engineers as well as university teachers
and students.
Dissipativity, as a natural mechanism of energy interchange is
common to many physical systems that form the basis of modern
automated control applications. Over the last decades it has turned
out as a useful concept that can be generalized and applied in an
abstracted form to very different system setups, including ordinary
and partial differential equation models. In this monograph, the
basic notions of stability, dissipativity and systems theory are
connected in order to establish a common basis for designing system
monitoring and control schemes. The approach is illustrated with a
set of application examples covering finite and
infinite-dimensional models, including a ship steering model, the
inverted pendulum, chemical and biological reactors, relaxation
oscillators, unstable heat equations and first-order hyperbolic
integro-differential equations.
CAMD or Computer Aided Molecular Design refers to the design of
molecules with desirable properties. That is, through CAMD, one
determines molecules that match a specified set of (target)
properties. CAMD as a technique has a very large potential as in
principle, all kinds of chemical, bio-chemical and material
products can be designed through this technique.
This book mainly deals with macroscopic properties and therefore
does not cover molecular design of large, complex chemicals such as
drugs. While books have been written on computer aided molecular
design relating to drugs and large complex chemicals, a book on
systematic formulation of CAMD problems and solutions, with
emphasis on theory and practice, which helps one to learn,
understand and apply the technique is currently unavailable.
-This title brings together the theoretical aspects related to
Computer Aided Molecular Design, the different techniques that have
been developed and the different applications that have been
reported.

of CAMD
