Catalyst Coke Reduction of Biomass using Cerium-Containing Zeolites


Creating stable and usable biofuels hinges on the development of highly active and selective heterogeneous catalysts that are robust toward the many components and types of biomass. A universal catalyst capable of handling the complex, highly oxygenated biomass feedstock currently does not exist. Therefore, the development of new catalysts designed with the benefits of currently employed catalysts with additional capabilities for upgrading complex feedstocks is paramount if 2nd generation biomass utilization is envisioned as a commercial process.  Due to the large amount of oxygen and alkali metal contaminants, current industrial petroleum catalysts are quickly deactivated when used as biomass upgrading catalysts. The large carbon deposition on these zeolite catalysts minimize their time in the reactor, overall lifetime, and overall conversion to more useful products. ND researchers have developed a synthetic method to generate more robust zeolite catalysts to reduce the coke formed during catalytic fast pyrolysis of biomass. Using this catalyst, the coke reduction is ~ 30-50%.
