REGENERABLE HYDROCARBON CONVERSION PROCESS USING A FLUORIDE-SENSITIVE CATALYST AND A FLUORIDE-FREE FEED

摘要

"REGENERABLE HYDROCARBON CONVERSION PROCESS USING A FLUORIDE-SENSITIVE CATALYST AND A FLUORIDE-FREE FEED" A regenerable hydrocarbon conversion process operating on a fluoride-containing feed stream is disclosed which extends the useful life of a regenerable zeolitecontaining hydrocarbon conversion catalyst used therein by passing the hydrocarbon feed containing fluorides through a fluoride removal system which reduces the fluoride concentration of the feed to below 100 ppb. The zeolitecontaining hydrocarbon conversion catalyst is periodically regenerated with an oxygen-containing gas stream as necessary to burn off carbonaceous deposits on the catalyst so as to return the zeolite catalyst to a high level of activity without interference by detrimental fluoride compounds that otherwise would be contained in the carbonaceous deposits.
