A system and method for synthesizing gaseous aromatic hydrocarbons, the system comprising a synthesis gas purification unit (1), a synthesis gas conversion unit (2), a synthesis gas aromatic hydrocarbon unit (3), a gas-liquid separation unit (4), and a liquefied gas separation Unit (5), dry gas separation unit (6), dry gas conversion unit (7), oil-water separation unit (8). The method returns the synthesis gas aromatization reaction system by separating the liquefied gas, the separation of the dry gas and the steam reforming of the dry gas to form carbon monoxide and hydrogen, which not only solves the problem of utilization of by-products but also reduces the product of the toluene. The unit gas consumption. The system and method from the perspective of circular economy, at the same time solve the problem of utilization of by-product dry gas, reduce the water consumption in the process, in line with the concept of green chemistry. |
