Syngas to olefins (SGTO) is the reaction of syngas (H2+CO) to C2~C4 olefins and byproduct gas oil, diesel, which the product composition is very complex, including C1~C20+ hydrocarbons, oxygenerates and other inorganic components.The method is the important way that make coal, natural gas into fuels, and also the efficient and cleanly way of using coal. Analysis and characterization of SGTO products are the eyes of evaluating the catalytic performance and optimizing the process conditions. The mature and re...
