Study on the modification of Cu-based catalysts with CUPRIC SILICATE (cas 16509-17-4) for methanol synthesis from synthesis gas08/08/2019

Small amount of cupric silicate was incorporated into copper-based catalyst to produce a series of modified ternary Cu–Zn–Al catalysts for methanol synthesis from synthesis gas. The test results showed that the Cu-based catalyst modified with 1% CuSiO3 exhibits the highest activity. The cupric...detailed
