| titleOfInvention | A kind of high-pressure low-temperature sulfur-resistant pre-shift catalyst and preparation method and application |
| abstract | The invention provides a high-pressure and low-temperature sulfur-resistant pre-shift catalyst, a preparation method and an application, comprising an active component, a carrier and an auxiliary, the carrier supports the active component and the auxiliary, and the active component is a cobalt-containing compound and a molybdenum-containing compound, The carrier is gibbsite and nano-titanium dioxide, and the auxiliary includes lanthanum-containing compound, cerium-containing compound and potassium-containing compound, and the potassium element in the potassium-containing compound is provided by mica stone. The present invention adopts mica stone to provide potassium element as alkali metal potassium auxiliary agent, and mica stone can form a special structure in the catalyst body, so that stable interaction between potassium ions and adjacent elements can be formed, thereby effectively preventing the loss of potassium element, and significantly The low-temperature shift activity of the pre-shift catalyst is improved, and at the same time, the loss of alkali metal promoters during the use of the catalyst is effectively avoided. |
