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.
采用锌-铜催化剂对CO NIAP-06-06在甲醇合成中的蒸汽重整进行了研究。通过N2的TPV、XRF和SEM对催化剂进行了表征。在压力5.0 MPa、GHSV 3000 h−1、温度220 ～ 260℃范围内，以流动和循环方式合成甲醇。结果表明，该催化剂对H2: CO = 3.9的甲烷蒸汽重整气合成甲醇具有较高的活性和选择性。采用串联管式催化反应器的工艺模式，允许一个流动循环70多个% 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.
