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. WebSince the low temperature shift catalyst is relatively expensive, the optimum CO conversion is to take about 90% conversion over the high temperature shift catalyst followed then by a low temperature shift conversion for the remainder (B-3).
