Abstract
A novel steam reforming catalyst comprising hibonite and potassium beta-alumina with improved resilience, improved activity, reduced potassium leaching and reduced coking problems. It also regards a method for producing the novel catalyst and uses of the novel catalyst in reforming reactors, in a plant for producing hydrogen gas, or in a plant for producing synthesis gas.
Claims21
A catalyst support for use in steam reforming, the support comprising at least 35 wt % hibonite and 10-35 wt % potassium beta-alumina upon sintering, wherein the composition is essentially free of alumina spinel.
A catalyst support for use in steam reforming, the support comprising at least 35 wt % hibonite and 10-35 wt % potassium beta-alumina upon sintering, wherein the molar ratio of Ca:Al:Ti:K is in the range of 1:(8-20):(0.01-0.5):(0.05-1.0).
A catalyst support for use in steam reforming, the support comprising at least 35 wt % hibonite and 10-35 wt % potassium beta-alumina upon sintering, wherein the support comprises titanium in the range of from 0.1 to 2.7 mol %.
A catalyst support for use in steam reforming, the support comprising at least 60 wt % hibonite, 10-35 wt % potassium beta-alumina, and grossite, upon sintering.
