Abstract: Processes and apparatus for reforming hydrocarbons to reduce the impact of contaminants created by non-catalyst coking. The reaction zone receives sulfur to inhibit the impact, and a control index is used to control the determine conditions with generally lower pressures. Additionally, a compression zone, pressure control zone and combustion zone operation are provided for the operation of the reaction zone at the generally lower pressures.

Abstract: A naphtha cracking feed stream is taken, heated and passed to a cracking reactor. Hydrogen is added to the cracking reactor to mitigate catalyst deactivation. The aliphatic compounds are selectively cracked and at least a portion of the alkyl groups on the aromatic compounds are selectively dealkylated in the presence of a cracking catalyst to produce a cracked effluent stream comprising aromatic compounds and cracked olefins.
