【Ten Years of Great Progress in Chemical Technology】097–2023: Pre-conversion + single-stage conversion process for hydrogen production from 100,000 cubic meters per hour of natural gas
Thread Content
Ten years of rapid development in chemical technology; praise for the prosperous and strong China. This is just a starting point to encourage more participation from everyone. HaiChuan becomes even better with your involvement; we welcome all to join in the forum discussions. Everyone should focus on safety and know how to handle emergencies. ********************************************* Recently, China’s largest single-unit natural gas hydrogen production facility, with a capacity of 100,000 cubic meters per hour, operated by Zhejiang Petrochemical – and which relies on core catalysts provided by Sichuan Southwest Chemical Research and Design Institute Co., Ltd. (hereinafter referred to as “Southwest Institute”) under Sinopec – was successfully put into operation. It is reported that the device employs a pre-conversion + single-stage conversion process technology. The pre-conversion reactor is filled with a new generation of CN-14R pre-conversion catalyst provided by the Southwest Research Institute; this catalyst features a stable structure, strong resistance to carbon deposition, and is of the pre-reduction type. With the use of this catalyst, the cold-start time for the plant is less than 10 hours; within half an hour after feeding the materials, the reaction meets the requirements specified in the process design. The methane content in the outlet process gas drops to around 73%, while the concentration of hydrocarbons with a molecular weight greater than C2 is less than 0.1%. This significantly reduces the plant’s startup time and saves the owner a considerable amount of costs associated with startup.
