WebThe high temperature shift (HTS) converter is the first stage of the water-shift conversion reactions to convert the CO in the raw syngas from the secondary reformer. The water-shift reaction converts CO in the presence of steam into H 2 and CO 2. Steam injection flow … WebThe LTS shift converter unit, over a commercial Cu/ZnO/ Al 2 O 3 catalyst (methanol synthesis catalyst), then converts majority of remaining CO, to a concentration of ~1000ppm (or, 0.1%). The inlet temperature of the gas stream entering the LTS converter unit is typically in the range of 190-230 oC and is operated in the adiabatic mode [7-9].
