One kind of residue coking process

The present invention provides a residual coking process, which comprises catalytic cracking heavy cycle oil and hydrogen with a hydrogenation catalyst to carry out hydrogenation reaction, the hydrogenation to give cracking heavy cycle oil; hydrogenated after the the mixture is mixed with the heavy cycle oil catalytic cracking residue, was subjected to coking. Coking residue mixed with coking process according to the present invention resid catalytic cracking heavy cycle oil hydrogenation, can significantly improve the yield of liquid products.
