A PROCESS FOR PRODUCING DIMETHYL CARBONATE FROM CARBON DIOXIDE GENERATED IN THE INDUSTRY PROCESS AND SYSTEM

摘要

In one aspect, disclosed is a mixture comprising dimethyl carbonate, in which, at least 2/3 carbon atom of said dimethyl carbonate is coming from the carbon dioxide generated as a byproduct in at least one industry process. In another aspect, disclosed is a process for producing dimethyl carbonate, in which, a coal is converted into liquid product in the hydrogen atmosphere, and ammonia and carbon dioxide are obtained as byproduct,  at least a portion of said carbon dioxide and ammonia are reacted to product urea, and a portion of carbon dioxide is fed into at least an area cultivating biomass, syngas is obtained from the biomass cultivating, and at least a portion of said syngas is converted to methanol in the presence of catalyst, then said methanol and urea are reacted to produce dimethyl carbonate.
