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.
Claims18
A improved steam reforming process, comprising
- a) operating a steam reforming process in a steam reforming reactor system at a first steam to carbon ratio;
- b) providing a protective layer to at least a portion of said steam reforming reactor system, wherein said layer was prepared by applying a plating, cladding, paint or other coating to at least a portion of a steam reforming reactor system, said protective layer being effective to reduce the amount of undesirable by-products in said process;
- and
- c) operating the steam reforming process at a second steam to hydrocarbon ratio that is at least 5% lower than said first steam to carbon ratio.
An improved commercial scale steam reforming process, comprising providing a metallic protective layer to a steel portion of a steam reforming reactor system, wherein said layer was prepared by applying a metal plating, cladding, paint or other coating to at least a portion of a steam reforming reactor system, said coating being effective to reduce the amount of undesirable by-products in said process;
- and using said protected reactor system for steam reforming at low steam to carbon ratios.
