Abstract: To utilize the high aromatic in catalytic cracking diesel,technology for producing rocket kerosene from catalytic cracking diesel through feedstock and product distillation optimization and deep hydroprocessing has been developed. The results of the pilot-scale tests showed that typical catalytic cracking diesel feedstock was fractionated to obtain the light fraction with suitable distillation range. With high-activity hydroprocessing catalysts and reasonably fractionating the hydrogenation product, rocket kerosene that meets the national rocket jet fuel standard was obtained. The technology has been commercially applied in SINOPEC Jingmen Company and can produce qualified ton-level rocket kerosene products, which have qualified heat transfer and coking performance. The technology has a good application prospect.

Key words: catalytic cracking diesel, rocket kerosene, hydrogenation, fractionation
