WebHigh-temperature shift conversion; Purification by pressure swing adsorption; An HTCR reactor absorbs about 80% of the heat released by the burner into the process. This compares to about 50% in a traditional fired tubular reformer featuring radiant heat transfer. The main fuel used for the HTCR burner is PSA off-gas. WebThe rest of the gas passes down through a top layer of catalyst in an axial direction, eliminating the need for a top cover on the catalyst bed. Casale’s axial-radial catalyst bed technology is used in both high-temperature and low-temperature shift converters, as well as in the synthesis converter. Other technologies
