Abstract: The coker dry gas hydrofining process and appropriative catalyst LH-10D, developed by FRIPP, to prepare the feedstock for ethylene production was introduced. The optimized technical conditions are: a temperature of 240-300 ℃，a pressure of 3.5-7.0 MPa , a GHSV of 600-1 300 h-1. Under the conditions, the olefin content of the product is less than 1.0% and oxygen content is less than 1.0 mg/m3. The 1 800 h long-running test proves a good activity and stability of the catalyst.

Key words: coker dry gas, hydrogenation, feedstock for ethylene production
