DEHYDRATION OF GLYCEROL TO ACROLEIN IN A FLUIDIZED BED REACTOR - (PPT)

摘要

Acrolein is a valuable chemical that can be produced by the dehydration of glycerol. The value of glycerol, as the main co-product in the process of biodiesel synthesis, has dropped considerably due to a rapid increase in biodiesel production and a lack of market for such an enormous production capacity. Therefore, the dehydration of glycerol to acrolein is one of many reactions under development, which aims to convert low cost feedstock to more valuable products. Catalyst deactivation, on the other hand, which is caused by coke formation on the surface, is a serious issue for the commercialization of this process. In the case of glycerol dehydration, although acidic sites help to enhance the acrolein selectivity, they also accelerate catalyst deactivation. Acrolein could be a source of carbon build-up, as well.
