“…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.

“…Most of those processes are solvent-free, and are often conducted in the gas phase at elevated temperatures. [2] These features have made it possible for petrochemical conversion to operate at very large scale and to be very profitable. [3] However, despite the presence of these well-established and robust commercial processes for producing carbon-based products, there is increasing interest in finding renewable carbon sources to replace fossil resources.…”

Biomass is a possible renewable alternative to fossil carbon sources. To day, many bio-resources can be converted to direct substitutes or suitable alternatives to fossil-based fuels and chemicals. However, catalyst deactivation under the harsh, often liquid-phase reaction conditions required for biomass treatment is a major obstacle to developing processes that can compete with the petrochemical industry. This review presents recently developed strategies to limit reversible and irreversible catalyst deactivation such as metal sintering and leaching, metal poisoning and support collapse. Methods aiming to increase catalyst lifetime include passivation of low-stability atoms by overcoating, creation of microenvironments hostile to poisons, improvement of metal stability, or reduction of deactivation by process engineering.

“…In the case of ethane, added along with naphtha in the feed stream, yields of C2H4 can reach 80 wt. % [5]. Its eminent industrial uses cause the world demand for C2H4 to incessantly increase, as it can be used for significant applications, such as the production of intermediate chemicals, mainly in the industry of plastics.…”

Over the last decade, increasing demand for olefins and their valuable products has prompted research on novel processes and technologies for their selective production. As olefins are predominately dependent on fossil resources, their production is limited by the finite reserves and the associated economic and environmental concerns. The need for alternative routes for olefin production is imperative in order to meet the exceedingly high demand, worldwide. Biomass is considered a promising alternative feedstock that can be converted into the valuable olefins, among other chemicals and fuels. Through processes such as fermentation, gasification, cracking and deoxygenation, biomass derivatives can be effectively converted into C 2 -C 4 olefins. This short review focuses on the conversion of biomass-derived oxygenates into the most valuable olefins, e.g., ethylene, propylene, and butadiene.
