Abstract:
1. A process for producing reduced acid lignocellulosic-derived pyrolysis oil comprising: feeding lignocellulosic material to a heating zone; delivering a basic solid catalyst to the heating zone; pyrolyzing the lignocellulosic material in the presence of the basic solid catalyst in the heating zone to create pyrolysis gases; catalytically converting oxygen in the pyrolysis gases to separable species in the heating zone, the pyrolysis gases including carboxylic acids and wherein more than 30% of the carboxylic acids are converted; removing the pyrolysis gases from the heating zone; and liquefying the pyrolysis gases to form the reduced acid lignocellulosic-derived pyrolysis oil.
