FIELD: petroleum processing and petrochemistry. ^ SUBSTANCE: method resides in preliminarily mixing starting feedstock with (i) liquid hydrogen-donor additive having 4-10% active hydrogen and taken in amount 0.5-1.0% of the weight of feedstock and (ii) coke scavenger taken in amount 0.5-5%, after which resulting three-component mixture is dispersed and activated. Thermal hydrocracking of the mixture is conducted at elevated temperature and pressure. Coke scavenger is withdrawn out of the process together with residual products. ^ EFFECT: increased yield of desired products and reduced coking on equipment walls due to the presence of hydrogen-donor additive and coke scavenger. ^ 7 cl, 1 tbl, 5 ex |
