The invention discloses an alcohol substance and biomass co-pyrolyzing method which is mainly characterized by adding the certain amount of alcohol to serve as active radical and hydrogen donor in a biomass pyrolysis or pyrolyzed product catalytic cracking reaction process, enabling active radical generated by alcohol pyrolysis to be combined with pyrolysis radical and accordingly achieving the effects of stabilizing pyrolyzed intermediate products, reducing pyrolyzed carbon deposition amount and reducing pyrolyzed product viscosity. Meanwhile, serving as the hydrogen donor, the alcohol can provide a hydrogen source for a reaction system in pyrolysis or catalytic cracking process to achieve the effects of hydrogenation, deoxygenation and the like of the pyrolyzed product. 本发明公开了种醇类物质与生物质共热解的方法，其主要特征在于，在生物质热解或热解产物催化裂解反应过程中，加入定量醇类物质作为活性自由基及氢的供体，使得醇类裂解产生的活性自由基与热解自由基结合，从而起到稳定热解中间产物、降低热解积碳量、降低热解产品粘度的作用；同时，作为氢供体，醇类物质在热解或催化裂解过程可为反应体系提供氢源，以起到热解产物加氢、脱氧等作用。
