Oilseed biorefinery

Development of value-added products from glycerol can help the total economics of an oilseed biorefinery. Propylene glycol is one such product. This chapter will present the development of catalysts that can convert glycerol to propylene glycol in high yields. Our work has focused on a class of catalysts based on Re, which as a cometal imparts important character to the catalysts. 

Current oilseed biorefineries (see Figure 17.4) mainly produce food and feed ingredients, and biodiesel and oleochemical products from oilseeds, such as rape, sunflower and soybean. 

A wide range of food materials are used as feedstocks in biorefinery. Even biorefineries can be classified, based on the food materials used, into three major groups (1) cereal biorefinery, (2) green biorefinery, and (3) oilseed biorefinery. The cereal biorefinery uses stable dry cereals...

The impact of the vegetable oil biorefinery on our environment has to take an important part of the future industrialization of biobased products. The oilseed crops production has a positive effect on GHG emissions, but its influence on land uses needs to be evaluated to reach a sustainable economy. Water could become a rare commodity in a large number of locations and the consequences of the emergence of vegetable oil biorefineries on water supply have to be studied. The biodiversity is an important factor to be...

Biodiesel is currently produced mainly from oilseeds leading to the generation of sig-nificant quantities of by-product streams, namely cmde glycerol (10% w/w) and oilseed meals. These by-product streams could be recycled for the production of SCO-derived biodiesel through integrated bioprocesses employing a biorefinery approach.
