A process for producing a para-xylene product from a hydrocarbon feed includes: hydrocracking the hydrocarbon feed in the presence of a catalyst to obtain a hydrocracking product; separating the hydrocracking product to obtain a gas stream and a liquid stream, the liquid stream comprising benzene, toluene, xylene, C9+ hydrocarbon, or a combination comprising at least one of the foregoing; separating the liquid stream to obtain a toluene stream, wherein toluene is present in the toluene stream in an amount equal to or greater than 70 wt %, preferably equal to or greater than 80 wt %, more preferably equal to or greater than 95 wt %, based on the total weight of the toluene stream; and reacting the toluene stream with methanol to obtain the para-xylene product.
一种利用碳氢化合物原料生产对二甲苯产品的工艺包括在催化剂存在下对碳氢化合物进料进行加氢裂化,得到加氢裂化产物; 分离加氢裂化产物,得到气流和液流,液流包括苯、甲苯、二甲苯、C9+碳氢化合物或至少包括上述一种的组合;分离液流以获得甲苯流,其中甲苯在甲苯流中的含量等于或大于 70 wt %,优选等于或大于 80 wt %,更优选等于或大于 95 wt %(基于甲苯流的总重量);以及 将甲苯流与甲醇反应以获得对二甲苯产品。
