WebHigh temperature (HT) CO shift conversion at about 300 to 450 °C down to approx. 2.5 % CO on dry basis at the reactor outlet. Medium temperature (MT) CO shift conversion or so … WebAbstract. A rate equation for water-gas shift reaction over a high-temperature shift catalyst (Fe/sub 2/O/sub 3/-Cr/sub 2/O/sub 3/) has been developed. This rate equation accounts …
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 ... 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 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%. Webrates would be useful in the design of high temperature, hydrogen-permeable membrane reactors. The reverse water-gas shift reaction, rWGSR, is the focus of this investigation. …
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.
WebThe operation of HTS catalysts occurs within the temperature range of 310 °C to 450 °C.
