NOVELTY - Bio-oil esterification involves adding 0.1-5 pts. wt. graphene oxide into 100 pts. wt. bio-oil at 45-55 degrees C for carrying out ultrasonic dispersion for 10-20 minutes to prepare graphene oxide-containing bio-oil. The obtained graphene oxide-containing bio-oil is added to a surface contact friction test machine oil box for carrying out friction treatment under controlled friction process conditions to obtain the esterifed bio-oil. USE - Method for esterifying bio-oil through friction catalysis (claimed). ADVANTAGE - The method provides in situ esterification of the bio-oil in a simple manner with high utilization rate and low corrosion.
