Study on reaction rates for methanol synthesis from carbon monoxide, carbon dioxide, and hydrogen
The reaction rates for methanol synthesis from carbon monoxide, carbon dioxide, and hydrogen over a copper-zinc-based catalyst were measured under the following conditions: temperature, 210-300/sup 0/C; pressure, 4-10 MPa, feed gas composition H/sub 2//CO 2.7-720, H/sub 2//CO/sub 2/, 4.3-120, CO/sub 2//CO, 0.05-180 (in moles). It was concluded that direct methanol production from CO/sub 2/ takes place under the above conditions in addition to the two well-known reactions, methanol synthesis from CO and CO formation from CO/sub 2/. Empirical rate equations for the three reactions were derived. From the viewpoint of reaction rates, the effect of each component, especially that of CO/sub 2/, was discussed.
