Abstract
A hydrocarbon conversion process is disclosed having a very high selectivity for dehydrocyclization. In one aspect of this process, a hydrocarbon feed is subjected to hydrotreating, then the hydrocarbon feed is passed through a sulfur removal system which reduces the sulfur concentration of the hydrocarbon feed to below 500 ppb, and then the hydrocarbon feed is reformed over a dehydrocyclization catalyst comprising a large pore zeolite containing at least one Group VIII metal to produce aromatics and hydrogen.
Claims14
A hydrocarbon conversion process comprising reforming a hydrocarbon feed having a sulfur concentration of below 100 ppb over a catalyst comprising a large-pore zeolite containing at least one Group VIII metal to produce aromatics and hydrogen.
A hydrocarbon conversion process comprising:
- (a) subjecting a hydrocarbon feed to hydrotreating;
- (b) passing said hydrotreated hydrocarbon feed through a sulfur removal system to reduce the sulfur concentration of said hydrotreated hydrocarbon feed to below 100 ppb;
- and
- (c) reforming said hydrotreated hydrocarbon feed having a sulfur concentration of below 100 ppb over a dehydrocyclization catalyst comprising a type L zeolite containing at least one Group VIII metal to produce aromatics and hydrogen.
A hydrocarbon conversion process comprising reforming a hydrocarbon feed over a catalyst comprising a type L zeolite containing at least one Group VIII metal to produce aromatics and hydrogen, wherein said hydrocarbon feed has a sulfur concentration of below x ppb, wherein x is determined from the formula ##EQU3## where WHSV is the weight of feed per hour per weight of catalyst, hour.sup.-1, and
- .theta. is the desired run length in days.
