Abstract
A improved hydrocarbon conversion process, comprising applying a plating, cladding, paint or other coating to at least a portion of a hydrocarbon conversion reactor system which is used to convert hydrocarbons to products in the presence of steam, said coating being effective to reduce the amount of undesirable by-products in said process; and operating the hydrocarbon conversion process at a steam to hydrocarbon ratio that is lower than the steam to hydrocarbon ratio at which said process was operated prior to applying said coating. Preferred hydrocarbon conversion process includes steam cracking of hydrocarbons to produce ethylene and dehydrogenation of ethylbenzene to styrene.
Claims29
A method for hydrocarbon conversion, comprising converting a hydrocarbon in a hydrocarbon conversion reactor comprising a surface that comprises a metal-containing coating exposed to said hydrocarbon, wherein said converting is conducted at a steam to hydrocarbon ratio at least 5% less than a steam to hydrocarbon ratio required for said converting using a hydrocarbon reactor without said metal-containing coating.
A method for hydrocarbon conversion, comprising converting a hydrocarbon in a hydrocarbon conversion reactor comprising a surface that comprises a metal-containing coating exposed to said hydrocarbon, wherein said converting is conducted at a steam to hydrocarbon ratio at least 5% less than a steam to hydrocarbon ratio required for said converting using a hydrocarbon reactor without said metal-containing coating, and wherein said metal-containing coating comprises a metal in effective proportion selected from the group consisting of aluminum, antimony, arsenic, bismuth, gallium, germanium, indium, lead, tin and intermetallic compounds and alloys thereof.
A method for hydrocarbon conversion, comprising converting a hydrocarbon under conditions of low sulfur in a hydrocarbon conversion reactor comprising a surface that comprises a metal-containing coating exposed to said hydrocarbon, wherein said converting is conducted at a steam to hydrocarbon ratio at least 5% less than a steam to hydrocarbon ratio required for said converting using a hydrocarbon reactor without said metal-containing coating.
