“…These light hydrocarbons are thermally cracked to form ethylene and propylene, which, along with benzene, are the primary building blocks of the industrial chemical enterprise. The ethylene, propylene and benzene platform chemicals are subsequently converted through oxidation, oligomerization, alkylation, etc to a broad array of industrial chemical products (Chenier, 2002;Heaton, 1991;Matar and Hatch, 1994). As an example, the large-volume chemical products made from propylene are shown in Figure 1.…”

SummaryThe chemical industry is currently reliant on a historically inexpensive, petroleum-based carbon feedstock that generates a small collection of platform chemicals from which highly efficient chemical conversions lead to the manufacture of a large variety of chemical products. Recently, a number of factors have coalesced to provide the impetus to explore alternative renewable sources of carbon. Here we discuss the potential impact on the chemical industry of shifting from non-renewable carbon sources to renewable carbon sources. This change to the manufacture of chemicals from biological carbon sources will provide an opportunity for the biological research community to contribute fundamental knowledge concerning carbon metabolism and its regulation. We discuss whether fundamental biological research into metabolic processes at a holistic level, made possible by completed genome sequences and integrated with detailed structural understanding of biocatalysts, can change the chemical industry from being dependent on fossil-carbon feedstocks to using biorenewable feedstocks. We illustrate this potential by discussing the prospect of building a platform technology based upon a concept of combinatorial biosynthesis, which would explore the enzymological flexibilities of polyketide biosynthesis.

“…The detergents biodegradability is primarily affected by the structure of the side hydrocarbon chain in the LAB molecule: unlike the previously widely used alkylbenzenes with branched hydrocarbon chain, "linear" alkylbenzenes and corresponding synthetic detergents (SD) are almost completely decomposed by bacteria in natural conditions 8 . Another factor determining SD biodegradability is the fraction Figure 1.…”

“…In the stationary regime, given the hydrodynamic mode of ideal displacement, the change in the hydrocarbon concentration in terms of the reactor volume (contact time) can be written as follows: (2) For the evaluation of the hydrodynamic regime in the reactor the Peclet criterion calculation can be used 8 . This criterion expresses the ratio of convective and turbulent transport of the matter and can be calculated as follows: Pe=U*l/D (3) For the lengthy catalyst bed and the low intensity of mixing, Peclet criterion value is large and it corresponds to the plug-fl ow reactor model.…”

An approach to modelling of non-stationary catalytic processes of oil refi ning and petrochemistry is proposed. The computer modelling systems under development take into account the physical and chemical reaction laws, raw materials composition, and catalyst nature. This allows using the software for the optimization of process conditions and equipment design. The models created can be applied for solving complex problems of chemical reactors design; calculation of different variants of industrial plants reconstruction; refi ning and petrochemicals catalysts selection and testing; catalyst service life prolongation; determination of optimum water supply into the alkanes dehydrogenation reactor; optimization of products separation in the benzene alkylation process.

“…Research work on methods of production of 1,3--butadiene has been intensified in the last years because of its importance as a raw material for chemical industry -1,3-butadiene is the most important monomer in synthesis of rubber (SBR, NBR and others) and polyamides [1,2]. Because of commercial availability and relatively low price of light alkanes, dehydrogenation of n-butane to 1,3-butadiene has been generally accepted as a good way to produce this compound.…”

Commercial availability and low price of light alkanes make them very attractive in many branches of industry. Potentially interesting is their use in the process of oxidative dehydrogenation leading to production of olefins. This study was undertaken to characterise the oxidative dehydrogenation of n-butane to 1,3-butadiene (important substrate in production of synthetic rubber and polyamides) taking place over the modified carbon catalysts obtained from peach stones precursor. The catalytic tests were performed in the temperature range 250-450• C at oxygen/n-butane ratio of 1:1. For the majority of the activated carbon samples studied at the lowest temperature the only product was CO 2 . At 300• C the products of dehydrogenation of n-butane and side products appeared. With increasing temperature the amount of compounds generated increased and in the group of C4 hydrocarbons the dominant were 1-butene and 1,3-butadiene. The most effective catalyst was the sample oxidised with air, the least effective was the sample modified with ammonium peroxydisulphate.
