Abstract
With the goal of developing a process for producing high octane gasoline blending compounds from lignin, a series of Mo and NiMo catalysts on aluminophosphate supports, having P:A1 atomic ratios of 0 to 1, have been screened for their ability to hydrodeoxygenate and dealkylate a lignin model compound, 4-propylguaiacol. Their performance was compared to that of commercial Mo and NiMo catalysts on γ-alumina supports and with results reported in the literature using the same model compound. It was found that increasing the support acidity, by incorporation of phosphorus into the supports, led to a substantial increase in the production of dealkylated phenols and hydrocarbons, without decreasing the overall conversion. Control over the ratio of phenols to hydrocarbons was also achieved by varying the amount of phosphorus in the support, the inclusion or exclusion of Ni in the catalyst, as well as the temperature and space velocity of the reaction.
