Abstract
The present invention relates to a system and process for preparing aromatics from syngases, which has advantages of shortened flow process and reduced investment. The process comprises reforming the liquefied gas, separated dry gas with a water steam to produce carbon monoxide and hydrogen, which return, as raw materials, to the aromatization system, so that the problem of by-product utilization is solved, and the syngas unit consumption per ton of aromatic products is reduced. The problem of utilization of a dry gas as a by-product is also solved in the present invention from the perspective of recycling economy, which reduces the water consumption in the process, and conforms to the concept of green chemistry.
