Abstract

We investigated technology for converting coal into synthesis-gas under conditions of aerosol nanocatalysis and substantiated its expected benefits. They include a reduction in temperature, an increase in the rate of reactions as a result of mechanochemical activation of the catalyst and coal. The experiments were performed in a rotating reactor. A distinctive feature of a given reactor is that it rotates in the vertical plane (in contrast to reactors with a fluidized layer and a vibro liquefied layer). The increase in temperature increases the yield of hydrogen and carbon monoxide. We showed an increase in the ratio of CO:H2 caused by temperature. If we compare the new process to the steam conversion of methane, which proceeds at 800–900 С and at 2–2.5 bar, then the examined process of coal steam conversion using aerosol nanocatalysis proceeds stably at 600–700 С and at 1 bar. The difference between yields of products at different load of coal and at varying water feed rate is due to the influence of change in the molar ratio of the utilized raw materials on a change in part of certain reactions in the total quantity of reactions that occur during this process. The process of stone coal steam conversion is typically conducted at temperatures 1,000–1,100 С. In a given work, the temperature is much lower, by 350–450 С. This particular pattern is the advantage of carrying out this process using the technology of aerosol nanocatalysis
