High temperature shift reactor design
WebA high-temperature gas-cooled reactor (HTGR), is a nuclear reactor that uses a graphite moderator with a once-through uranium fuel cycle. The HTGR is a type of high-temperature reactor (HTR) that can conceptually have an outlet temperature of 750 °C (1,380 °F). The reactor core can be either a "prismatic block" (reminiscent of a conventional ... WebThe first, at high temperature, is called “HTS” for “high temperature shift” with a catalyst in general Fe2O3-Cr2O3. The gas cools, enters at 350°C and leaves at 400-450°C. For a “typical flow”, between 8 and 10% carbon monoxide (CO), the operation reduces the latter to 4%.

WebOct 6, 2004 · A new high-temperature reactor concept is being developed for hydrogen (H{sub 2}) and electricity production: the Advanced High-Temperature Reactor (AHTR). The goal is to develop a large economic reactor with passive safety systems that delivers high-temperature heat with the coolant exit temperature as high as 1000 deg. C. WebDec 4, 2024 · The water–gas shift reaction plays a major ro le in ammonia and hydrogen plant design and operation. Good performance of the shift catalysts, and att Water effect …
WebThe water-gas shift (WGS) reaction is an equilibrium-limited reaction at higher temperatures, usually kinetically limited below 250 °C. This requires development of more active low-temperature catalysts and advanced reactor concepts to overcome limitations related to low CO conversions in the range 250–350 °C.
