Abstract
Carbohydrates represent 75% of the renewable biomass on earth. They constitute a major class of feedstocks having the potential to yield products that can replace those derived from petroleum sources. Yet their present nonfood utilization is confined to the textile, paper, and coating industries in non derivatized forms or in the form of esters and ethers. Dehydration, etherification, esterification, oxidation, and the reduction of carbohydrates have been topics of interest for the past several years and many commercial processes do exist for such transformations. However, the inherent structure and properties of carbohydrates are quite different from conventional petroleum based feedstocks. In addition, the presence of other components in the bio-based feedstocks, along with the desired molecule of interest also raises issues pertaining to their compatibility with conventional catalysts and the impurity profile generated during reactions. Thus, applications of catalysis for renewable chemicals manufacture needs to overcome many challenges to ensure commercial success. This topic will highlight these efforts, challenges, and success stories in the journey towards such technology developments.
