Abstract
The invention discloses a method for preparing liquid fuel oil via catalytic cracking of biological oil and fat with USY as a catalyst. The method comprises the following steps of weighing the biological oil and fat and the USY catalyst according to a mass ratio of the biological oil and fat to the USY catalyst being 50 : 1-10; adding the biological oil and fat and the USY catalyst to a reaction kettle together; heating the reaction kettle to a temperature of 400-500 DEG C; performing catalytic cracking; and condensing the produced steam to obtain a dark brown liquid product. The product is mainly distributed between C8 and C10; the cracking rate of the biological oil and fat can reach over 90%; the yield of the liquid fuel oil can reach higher than 80%; and the USY catalyst has good service life.
Description
technical field [0001] The invention belongs to the technical field of biomass energy conversion, and mainly relates to a method for preparing liquid fuel oil by catalytically cracking bio-grease with USY as a catalyst. Background technique [0002] Biomass resources have CO in the process of energy utilization 2 The net emission is zero, and the characteristics of low emission of SOx and NOx. Therefore, with the depletion of primary energy such as petroleum and coal, people pay more and more attention to the research and development of biomass energy. Among them, the comprehensive utilization of bio-oils with triglyceride as the main component, such as soybean oil, rapeseed oil and waste oil, has attracted people's attention. Among many utilization methods, the catalytic cracking of biological oil to prepare liquid fuel oil is one of the effective means. Patent CN200910029495.X reports the use of oxides or hydroxides of alkali metals or alkaline earth metals, such as so...
