Combination hydrotreating and reforming process for converting low boiling normally liquid hydrocarbon materials to a variety of normally liquid and normally gaseous fuel products

摘要

Catalytic hydrotreating procedure for hydrocarbon distillates, characterized in that a hydrocarbon distillate feed charge, previously without hydro-refining, having a boiling temperature between 82º and 315.5ºC, containing a hydrocarbon distillate, is contacted. at least 40% by volume of materials with a boiling temperature on the order of 82º to 160ºC, 10 to 1000 parts per million sulfur and less than 300 parts per million nitrogen, with hydrogen and a hydrotreating catalyst comprising one component cracking silica and a hydrogenation-dehydrogenation component chosen from the group consisting of Group VIII metals, Group VIII metal oxides and Group VIII metal sulfides, said contact being made at a temperature of the order of 260º to 454.4ºC, a pressure of the order of 21.09 to 210.92 kgs/cm2 and a space velocity per hour of liquid of the order of 0.2 to 10, for which reason The charge is converted, in part, to hydrocarbons with boiling temperatures below 82ºC, including normally gaseous hydrocarbons and whereby, at least, a substantial part of the sulfur existing in said charge in a form other than H2S is converted to H2S, separating of the effluent from said hydrotreating zone at least one normally gaseous hydrocarbon fraction, a C5 hydrocarbon fraction with boiling temperatures on the order of 93.3ºC and a hydrocarbon fraction with boiling temperatures on the order of 82º to 232.2ºC, containing at least 40% by volume of materials with boiling temperatures of the order of 82º to 160ºC and less than 10 parts per million sulfur, said fraction having boiling temperatures between 82º and 232.2ºC being reformed to produce a high reforming octane number.
