High temperature shift converter

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. WebTo efficiently convert and utilize intermittent solar energy, a novel solar-driven ethanol steam reforming (ESR) system integrated with a membrane reactor is proposed. It has the potential to convert low-grade solar thermal energy into high energy level chemical energy. Driven by chemical potential, hydrogen permeation membranes (HPM) can separate the generated …

Webtemperature shift (HTS) reactor at 350-370°C. Conversion in the HTS reactor is limited by the equilibrium composition at the high temperature. To achieve higher conversions of CO to H2, the gas leaving the HTS reactor is cooled to 200-220°C and passed through a low-temperature shift (LTS) reactor (Kirk-Othmer, 1995; Ulllman’s, 1989). 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-called isothermal shift conversion at about 220 to 270 °C down to approx. 0.5 % CO on … 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.
