摘　　要：根据石油加工过程中油浆成垢的机理,确定了阻垢剂由清洁分散组分、抗氧组分、金属钝化组分及缓蚀组分组成。在实验室以聚丁二烯硫基磷酸和己二醇为原料合成了作为清洁分散组分的聚丁二烯硫基磷酸己二醇酯,并考察了所配阻垢剂的防垢效果。结果表明,阻垢剂在最佳用量150μg/g时,对催化裂化油浆的阻垢率最高可达92.07%。Based on analyzing the fouling mechanism of slurry oil in petroleum processing, several antifoulants were prepared including components for cleaning and dispersion, antioxidation, metal passivation and corrosion inhibition. The main cleaning and dispersion component was synthesized in lab using po- lybutadiene thiophosphoric acid and hexanediol as raw materials. The antifouling performance of the prepared antifoulants was tested. Results showed that using FCC slurry as feed under the testing conditions, with an optimum antifoulant dosage of 150 ug/g, the antifouling rate of the optimum antifoulant reached 92.07%.
