High temperature shift
WebHigh temperature shift. Based on an iron-chrome formulation, our latest high activity catalysts for high temperature shift operations are the result of extensive catalyst … The LTS shift reactor operates at a range of 200–250 °C. The upper temperature limit is due to the susceptibility of copper to thermal sintering. These lower temperatures also reduce the occurrence of side reactions that are observed in the case of the HTS. Noble metals such as platinum, supported on ceria, have also … See more The water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen: CO + H2O ⇌ CO2 + H2 The water gas shift … See more The equilibrium of this reaction shows a significant temperature dependence and the equilibrium constant decreases with an increase in … See more The WGSR has been extensively studied for over a hundred years. The kinetically relevant mechanism depends on the catalyst … See more Since the water–gas shift reaction is an equilibrium reaction, there isn't a ‘reverse’ water–gas shift reaction. Water gas is defined as a fuel gas consisting mainly of carbon monoxide (CO) and hydrogen (H2). The term ‘shift’ in water–gas shift means changing the water … See more The WGSR is a highly valuable industrial reaction that is used in the manufacture of ammonia, hydrocarbons, methanol, and hydrogen. Its most important application is in conjunction … See more In order to take advantage of both the thermodynamics and kinetics of the reaction, the industrial scale water gas shift reaction is conducted in multiple adiabatic stages consisting of a high temperature shift (HTS) followed by a low temperature shift … See more • In situ resource utilization • Lane hydrogen producer • PROX See more
