Converting a stream containing heavy hydrocarbons into a stream containing hydrocarbons having a lower boiling range

摘要

Process for converting a stream containing heavy hydrocarbons comprising the steps of a) passing through a first conversion reactor (1) containing a conversion catalyst in the presence of hydrogen the stream at a temperature between 325 and 600 DEG C, a pressure between 1 and 30 MPa and at an hourly space velocity between 0.05 and 5 kg/1/hour to produce a primary converted stream; b) passing the primary converted stream to a first gas/liquid separator (4) and removing from the first gas/liquid separator (4) a gaseous stream and a liquid stream; c) passing the gaseous stream to a second conversion reactor (7); and d) passing through the second conversion reactor (7) containing a conversion catalyst in the presence of hydrogen the gaseous stream at a temperature between 325 and 600 DEG C, a pressure between 1 and 30 MPa and at an hourly space velocity between 0.1 and 10 kg/l/hour to produce a further converted stream having a lower boiling range. ;
