Transformation of Sorbitol to Biofuels by Heterogeneous Catalysis: Chemical and Industrial Considerations
Abstract : Decreasing oil supplies and increasing energy demand provide incentives to find
alternative fuels. First, the valorisation of edible crops for ethanol and biodiesel
production led to first generation biofuels. Nowadays, research is focused on
lignocellulosic biomass as a source of renewable carbon (second generation biofuels).
Whereas the cellulosic ethanol production is in progress, a new way consisting of the
transformation of ex-lignocellulose sugars and polyols towards light hydrocarbons by
heterogeneous catalysis in aqueous phase has been recently described.This process is performed under mild conditions (T < 300 °C and P < 50 bar). It
requires on one hand hydrogen formation by catalytic reforming of carbohydrates in aqueous
phase and on the other hand, the dehydration/hydrogenation of polyols leading to alkanes
by selective C-O bond cleavages. The challenge here is to conceive multifunctional
catalytic systems that are stable, active and selective under the reaction conditions.The aim of this article is to present the involved reactions, the catalytic systems
described in literature for that kind of transformation and examples of industrial
applications.
