The coking properties of hydrocracked residue from slurry bed hydrocracking of atmospheric residue from Xinjiang heavy oil were studied on a small experiment equipment.

The coking properties of hydrocracked residue from Tuozili Area in Liaohe Oil Field being taken as feed stock of delayed coking were studied on a small experiment equipment.

The static and dynamic tests of methane production from food wastes hydrogen-fermentation residue were done.

Establishment of 14 lumps model for fluid catalytic cracking of hydrotreated residuum;

According to the commercial data of 3~ # RFCCU processing hydrotreated residuum in Maoming petrochemical company and the character of hydrotreated residuum, the kinetic model with 7 lumps for hydrotreated residuum fluid catalytic cracking based on the four-component of residual was presented.

SHIFT-G technology of inverse catalyst loading is used to optimize the catalyst grading of residue hydrotreating.

The result showed,in spite of its higher one-off investments and process cost ,the economic benefit of residue hydrotreating-catalytic cracking combined process is still better due to its higher liquid yield and higher production value.

Measures,such as improving the coking performance of UFR catalyst,adopting SHIFT- G technology of inverse catalyst loading,as well as optimizing catalysts graded loading and operation conditions,were applied in the residue hydrotreating unit of Qilu Petrochemical Company.
