Over a period of several years, the Department of Forest Science at Texas A and M University has been conducting studies in the hydroprocessing (catalytic high pressure hydrotreating or hydrodeoxygenation accompanied by hydrocracking) of pyrolytic tars produced in biomass pyrolysis and gasification. Upgrading through hydroprocessing results in good yields of volatile hydrocarbon and phenolic products. This paper compares the performance of twenty different catalysts selected for hydroprocessing of a pine pyrolysis oil, describes the use of noble metal catalysts with tars produced from nine different biomass feedstocks (oil from pine pyrolysis and the tars from pine wood chip, pine plywood trim, pecan shell, peanut shell, sugarcane bagasse, corncob, rice hull, and cottonseed hull gasification), and compares the use of several catalysts in a trickle bed reactor for kinetic studies of the hyroprocessing reaction.
