METHOD OF PRODUCING FUEL DISTILLATES AND FUEL OIL Russian patent published in 2007 - IPC C10G9/00 

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 Coke scavenger is withdrawn out of the process together with residual products.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.
