Increasing production in hydrocarbon conversion processes

摘要

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.
