摘要： We disclose a single stage, multilayered catalyst system capable of hydrodewaxing and hydrofinishing a solvent-dewaxed lube oil base stock. In the first layer we catalytically dewax the solvent-dewaxed stock. In the second layer we hydrofinish the catalytically dewaxed stock. Our invention also relates to a process for hydrodewaxing and hydrofinishing a solvent-dewaxed lube oil base stock.

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.
摘要翻译： 一种改进的烃转化方法，包括将电镀，包覆，涂料或其它涂层施加到用于在蒸汽存在下将烃转化成产物的烃转化反应器系统的至少一部分，所述涂层有效地减少量 在所述方法中不期望的副产物; 并且在施加所述涂层之前，以低于所述方法操作的蒸汽/烃比例的蒸汽/烃比率操作烃转化过程。 优选的烃转化方法包括烃的蒸汽裂解以产生乙烯和乙苯脱氢成苯乙烯。
