WebTOPSOE™’s low methanol LTS catalyst LK-823 is developed in response to the increasing concern for methanol by-product formation over LTS catalysts. Similar to LK-821-2 catalysts, it is based on oxides of copper, zinc, and aluminum. LK-823 differs in being promoted with a small amount of cesium leading to obtaining improved selectivity. Application WebTo facilitate H2 plant operation, a Visual Basic program should calculate steam reforming equilibrium composition, steam reforming catalyst activity in terms of approach to equilibrium (ATE), high temperature shift (HTS) and low temperature shift (LTS) reaction equilibrium composition, HTS and LTS catalyst activities in terms of rate constants, …

WebThe high activity of the LTS catalyst results in the production of relatively large amounts of CH3OH in the process condensate and at times levels of up to 2000 ppm can be expected. The residual CH3OH content of the treated process condensate is expected to vary depending upon the amount in the stripper feed. WebTOPSOE™’s standard LTS catalyst LK-821-2 is a high-copper catalyst based on oxides of copper, zinc and aluminum. Global recognition of the superiority of the LK-821-2 has been demonstrated by industrial data through the years, making it the most widely used LTS catalyst in the world.

WebA comparison between the microkinetic model predictions for an isothermal PFR and the experimental results [13], is presented in Fig. 2 for the following conditions commercial low temperature shift Cu catalyst loading of 0.14 g/cm total feed flow rate of 236 cm (STP) min residence time r = 1.8 s feed composition of H20(10%), CO(10%), C02(0% ... WebThe lower limit of the operating temperature in the LTS reactor is the dew point of water at the operating pressure (190-200 °C at 30 bars). Condensed steam affects, adversely, the catalytic activity of the Cu-based LTS catalysts. The catalyst for the first stage reactor is Fe-Cr and for the second-stage reactor is Cu-based catalyst. WebThe water–gas shift (WGS) activity of Pt/TiO2-based powdered and structured catalysts was investigated using realistic feed compositions that are relevant to the high-temperature shift (HTS) and... graham directions
