CATALYTIC REFORMING PROCESSES

摘要

Processes for catalytic reforming in which a cracking inhibitor, such as an olefin, or a light olefin, is used to inhibit thermal cracking of larger hydrocarbons in non-reactive zones. The cracking inhibitor may be added at various positions through the processes, such as in the recycle gas stream, before a heater, before a stream is passed into a reforming zone, after an effluent stream is recovered from a reforming zone. A molar ratio of cracking inhibitor to hydrocarbons in stream may be between 0.01 and 0.2.

1. A process for reducing the thermal cracking in a catalytic reforming unit, the process comprising:
heating a feed stream comprising a hydrocarbons to provide a heated feed stream; reforming the hydrocarbons in the heated feed stream in a reforming zone, the reforming zone having catalyst and being configured to provide a reformate effluent stream; and, reducing thermal cracking of the hydrocarbons by mixing a cracking inhibitor with at least one of the feed stream, the heated feed stream, and the reformate effluent stream.
