Beschreibung
Zusammenfassung:	An 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. Procédé perfectionné de conversion des hydrocarbures, consistant à appliquer un plaquage, un gainage, une peinture ou tout autre type de revêtement sur au moins une partie d'un système de réacteur destiné à la conversion des hydrocarbures, lequel est utilisé pour transformer ces derniers en d'autres produits en présence de la vapeur, ledit revêtement permettant de réduire efficacement la quantité de sous-produits indésirables formés au cours de la mise en oeuvre de ce procédé; et à appliquer ce procédé de conversion des hydrocarbures avec un rapport vapeur/hydrocarbure inférieur au rapport vapeur/hydrocarbure utilisé dans de tels procédés de conversion avant que l'on n'applique un tel revêtement. On utilise de préférence, comme procédé de conversion des hydrocarbures, le craquage à la vapeur des hydrocarbures pour produire de l'éthylène et la déshydrogénation d'éthylbenzène en styrène.
