Study of the NIAP-06-06 Zinc–Copper Catalyst for the Steam Reforming of Carbon Monoxide in the Synthesis of Methanol

Abstract

A study is performed by using a zinc–copper catalyst for the steam reforming of CO NIAP-06-06 in the synthesis of methanol. The catalyst is characterized via the TPV of N₂, XRF, and SEM. It is tested in the synthesis of methanol in flow and circulation modes at a pressure of 5.0 MPa, GHSV of 3000 h⁻¹, and the 220–260°C range of temperatures. It is shown that the catalyst has high activity and selectivity in synthesizing methanol from gas obtained in the ratio H₂ : CO = 3.9 via the steam reforming of methane. Using a series of tubular catalytic reactors in the technological mode of a flow circle allows more than 70% of the CO to be processed and raw methanol to be obtained with a concentration of 95%. The performance of the catalyst for methanol is 427.7 kg/(\({\text{m}}_{{{\text{cat}}}}^{3}\) h) in the circulation mode.
