    Abstract: The present invention relates to synthetic hydrocarbons produced by skeletal isomerization, and the isomerization process. The products are especially useful as the continuous phase of a drilling fluid, for example when prepared from C14 to C18 linear alpha-olefins via isomerization or hydroisomerization, and as lube oils. The present invention also relates to a process for producing synthetic hydrocarbons by skeletally isomerizing C12+ olefins over a catalyst comprising an intermediate pore size molecular sieve, with or without Group VIII metals under skeletal isomerization conditions which result in little, preferably in subtantially no, olefin cracking or oligomerization.

    Abstract: A full boiling hydrocarbon feed is reformed to enhance para-xylene and benzene yields. First, the hydrocarbon feed is separated into a C5- cut, a C6-C7 cut, and a C8+ cut. The C6-C7 cut has less than 5 lv. % of C8+ hydrocarbon, and the C8+ cut has less than 10 lv. % of C7- hydrocarbon. The C6-C7 cut is subjected to catalytic aromatization at elevated temperatures in a first reformer in the presence of hydrogen and using a non-acidic catalyst comprising at least one Group VIII metal and a non-acidic zeolite support to produce a first reformate stream; and the C8+ cut is subjected to catalytic aromatization at elevated temperatures in a second reformer in the presence of hydrogen and using an acidic catalyst comprising at least one Group VIII metal and a metallic oxide support to produce a second reformate stream. Less than 20 wt.% of the total amount of C8 aromatics produced in the first and second reformer is ethylbenzene, and more than 20 wt.% of the total amount of xylenes produced in the first and second reformer are para-xylenes.

The method comprises applying a metal cladding, plating, paint or other coating to a stressed portion of austenitic stainless steel hydrocarbon conversion process equipment, optionally curing the coated steel to form intermetallic compounds to protect the steel portions; converting hydrocarbons utilizing a halided catalyst or under conditions where a halogen-containing compound is added or evolved or both; and subjecting the protected steel portion to halide stress-corrosion cracking conditions. A preferred coating material comprises tin, and preferably one or more intermetallic layers are provided to at least a portion of an austenitic stainless steel substrate to improve its stress-corrosion cracking resistance.
