    摘要: A method for directly producing an aromatic hydrocarbon from synthesis gas. The method comprises: a) enabling a feed stream comprising synthesis gas to contact a catalyst in a reaction zone under a reaction condition sufficient to convert at least a portion of the raw materials to obtain a reaction effluent; b) separating the reaction effluent to obtain at least a recycle stream comprising gas hydrocarbons having 1-4 carbon atoms and unconverted synthesis gas as well as a liquid stream comprising hydrocarbons having 5 or more carbon atoms; c) returning the recycle stream to the reaction zone; and d) separating the aromatic hydrocarbon product from the liquid stream, wherein the catalyst comprises an inert carrier-confinement high-dispersion metal oxide material, acidic molecular sieve, and at least one of graphite powder and dispersing agent optionally.

    摘要: A method for directly producing methyl acetate and/or acetic acid from syngas, whose reaction process is carried out in at least two reaction zones, the method comprises: feeding a raw material containing syngas into a first reaction zone to contact and react with a metal catalyst; allowing an obtained effluent to enter a second reaction zone directly or after the addition of carbon monoxide so as to contact and react with a solid acid catalyst; separating the obtained effluent to obtain product of acetate and/or acetic acid, and optionally returning a residual part to enter the first reaction zone and/or the second reaction zone to recycle the reaction. The present application provides a novel method for directly converting syngas into methyl acetate and/or acetic acid, the method having a simple processing procedure and high product selectivity. According to the method, the product selectivity of the product of methyl acetate or acetic acid is greater than 93%, and the quantity of methyl acetate and acetic acid may be adjusted according to processing, thus the method has great industrial application prospects.

    摘要: Disclosed is a method for directly preparing p-xylene from synthetic gas and an aromatic hydrocarbon. The method comprises: enabling a raw material containing synthetic gas and an aromatic hydrocarbon other than p-xylene to be contacted with a catalyst in a reaction zone under a reaction condition sufficient to convert at least part of the raw material, so as to obtain a reaction effluent containing p-xylene; and separating p-xylene from the reaction effluent. The catalyst contains at least one of an inert carrier limited-range high-dispersion metal oxide material, an acidic molecular sieve, and optional graphite powder, and a dispersing agent; in the inert carrier limited-range high-dispersion metal oxide material, the inert carrier is at least one of silicon oxide and aluminum oxide, and the metal oxide has a metal content of being less than or equal to 10 mass%; the inert carrier limited-range high-dispersion metal oxide material is measured by weight; the acidic molecular sieve is selected from a modified acidic ZSM-5 molecular sieve, a modified acidic ZSM-11 molecular sieve, and a mixture thereof.

    摘要: Disclosed herein is a method for directly producing ethanol from syngas, whose the reaction process is carried out in three reaction zones, and the method comprises: feeding a raw material containing syngas and dimethyl ether into a first reaction zone to contact with a solid acid catalyst, reacting; allowing the effluent from the first reaction zone to enter a second reaction zone to contact with a metal catalyst and react; separating the effluent from the second reaction zone to obtain product ethanol and by-product methanol; allowing by-product methanol to enter a third reaction zone to perform a dehydration reaction to obtain dimethyl ether, and allowing the obtained dimethyl ether to enter the first reaction zone to recycle the reaction. The present invention provides a novel method for directly converting syngas to ethanol. According to the method of the present invention, an ethanol product can be directly produced by using syngas as a raw material. Meanwhile, the method of the present invention has a simple processing procedure, low energy consumption, low production costs, and high product selectivity, and has great industrial application prospects.
