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 developments. They allow lower volumes of catalyst to be installed and increase the options for plant optimization. WebCarbon monoxide was removed in the low-temperature shift converter. At a temperature of 220°C (474 K) and with an approach to equilibrium given as 0°C, KP was calculated as 141.5. Using the equation for KP in terms of partial pressures, a value for the fractional conversion of carbon monoxide was calculated as 0.933.

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 WebThe low temperature shift converter contains one bed of catalyst with a volume of 108.8 m3. As the catalyst is self-guarding, the whole of the bed provides shift activity throughout the life of the charge, with the top portion of the bed retaining trace amounts of sulphur and chloride poisons that pass through the high temperature shift converter. iosco county parenting time policy
