Development and implementation of high effective and stable catalytic systems is the
most important stage of process optimization in chemical industry. The special attention is
given to the choice of a support, the material of which should have a number of
characteristics, such as a high surface area, advanced porosity, inertness and stability.
Recently different carbon materials have been used more widely in heterogeneous catalytic
processes.
One of more perspective carbon materials is carbon-carbon composite, which is referred
to a new class of carbon composites combining in itself advantages of graphite and active
carbons. Another very important advantage of this material is high chemical purity. Fraction
of mineral admixtures in sibunit is less than 1%, whereas mineral part of the main gamma of
active carbons is 5% and more. This characteristic of sibunit can brings essential influence on
selectivity of catalytic systems made on its base.
The next way of chemical industry progressing is development of alternative methods of
major organic compounds synthesis, which are characterized by a minimum quantity of
harmful waste and are based on renewed sources of raw material. Implementation of such
methods into the industry can afford improvement of economical efficiency as well as
ecological safety of these compounds production. One of such processes in chemical industry
is synthesis of acetaldehyde – the important intermediate of organic synthesis. The main
industrial method of acetaldehyde production is ethylene oxidation in the presence of aqueous
solutions of palladium and copper chlorides. This method is ecologically adverse and is based
on processing of oil raw material. For this reason the production of acetaldehyde by ethanol
dehydrogenation is extremely attractive. This process has a number of advantages: absence of
poisonous wastes, soft conditions of the process and the use of ethanol as the only raw
material, alternative production ways of which from biomass have been under active
development recently. However, for effective realization of this process, the development of
new active, selective and stable catalytic systems is needed.
