通过生物质裂解油和催化裂解精制油的物性和化学分析显示催化裂解精制油的密度、粘度、水含量较生物质裂解油明显降低,而pH值和热值明显提高。催化裂解精制油的碳含量较生物裂解油增加,氧含量降低。催化裂解精制油中的酸、醛、酮、糖和醇含量明显降低,酚和芳烃含量明显增加。说明经过催化裂解精制后的精制油的品质较精制前的生物裂解油明显提高。 Through the physical and chemical analysis of the biomass pyrolysis oil and the catalytic pyrolysis oil, the density, viscosity and water content of the catalytic pyrolysis oil were obviously lower than those of the biomass pyrolysis oil, but the pH and calorific value increased obviously. Catalytic cracking of refined oil carbon content than the bio-cracked oil increased oxygen content decreased. The contents of acids, aldehydes, ketones, sugars and alcohols in the FCC oil were significantly reduced, and the contents of phenol and aromatics increased obviously. It shows that the quality of refined oil after catalytic cracking is obviously improved compared with that before refined.
