Fischer-Tropsch synthesis

The highly active Co/SiO2 catalysts for FT synthesis were successively prepared by microwave irradiation. The main two advantages were the rapid preparation and the uniform distribution of Co particles which resulted in the high catalytic activity on FT synthesis as ashown in Figure

Methanol synthesis

Methanol is being produced by 30-40 million ton per year from CO/CO2/H2. It is commercially produced by ICI process at high temperature and pressure (523-573 K, 50-100 bar), using Cu/ZnO. However, at high temperature, the exothermic reactions thermodynamically limit theoretic CO conversion to about 10% at 573 K and 50 bar. Therefore, developing a low-temperature process will greatly reduce the production cost. A new low-temperature methanol synthesis from CO/H2 containing CO2 was proposed via reactions (1) - (3) where ROH acts as a catalytic solvent. This new process showed the high activity and selectivity of MeOH synthesis (CO conversion of 50% and MeOH selectivity of 98%) as shown in Figure.
