Platform chemical integrated biorefinery

Successful integration of carbohydrate chemistry in a biorefinery will greatly depend on the availability and price of the lignoceUulosic feedstock and its fractionation cost. Since the collection of biomass is Umited by its volume and density, biorefineries are likely to be smaller and more highly distributed than petroleum refineries. In order to produce meaningful volumes of products, a biorefinery should focus on a specific set of platform chemicals rather than attempting to provide an extended portfolio of products. There are two technological obstacles to the delivery of such a biorefinery, and effort is required to overcome them. First, the...

This chapter surveys different process options to convert terpenes, plant oils, carbohydrates and lignocellulosic materials into valuable chemicals and polymers. Three different strategies of conversion processes integrated in a biorefinery scheme are proposed from biomass to bioproducts via degraded molecules , from platform molecules to bioproducts , and from biomass to bioproducts via new synthesis routes . Selected examples representative of the three options are given. Attention is focused on conversions based on one-pot reactions involving one or several catalytic steps that could be used to replace conventional synthetic routes developed for hydrocarbons. 

The biorefinery scheme was developed initially for carbohydrate-containing feedstocks. Large biorefineries are currently operating in the USA (e.g., Cargill at Blair, Nebraska) and in Europe (e.g., Roquette Frs. at Lestrem, France). The concept can be extended to produce chemicals from other renewable feedstocks. An integrated production of oleochemicals and biofuels can be achieved in biorefineries using vegetables oils as main feedstock to produce versatile platform mole-...
