HIGHER ALCOHOL SYNTHESIS OVER A Cs-Cu/ZnO/Cr_2O_3 CATALYST: EFFECT OF THE REACTION TEMPERATURE ON PRODUCT DISTRIBUTION AND CATALYST STABILITY

摘要

The influence of reaction temperature on methanol and higher alcohol syntesis has been investigated in the range of 310-340℃. Optimal conditions for selective production of 2-methyl primary alcohols was identified with T = 340℃ and synthesis gas H_2/CO = 0.75. Deactivation features were observed after 300 hr on stream, but no significant growth of Cu crystals or reduction in surface area was observed for the catalyst after testing.
