Claim:
1. A process for reducing the thermal cracking in a catalytic reforming unit, the process comprising: heating a feed stream comprising hydrocarbons in a first heating zone and passing the feed stream from the first heating zone to a first reforming zone; reforming the hydrocarbons in the feed stream in the first reforming zone, the first reforming zone having catalyst and being configured to provide a reformate effluent stream; recovering the reformate effluent stream from the first reforming zone; mixing the reformate effluent stream with a light olefin stream as a cracking inhibitor to reduce thermal cracking of hydrocarbons before the reformate effluent stream is passed to a second reforming zone, wherein a molar ratio of light olefins to hydrocarbons in the reformate effluent stream is between 0.01 and 0.2; passing the reformate effluent stream to the second heating zone and heating the reformate effluent stream in the second heating zone; passing the reformate effluent stream from the second heating zone to a second reforming zone; and, reforming the hydrocarbons in the reformate effluent stream in the second reforming zone, the second reforming zone having catalyst and being configured to provide a second reformate effluent stream.
