Method for preparing refractory material with catalytic function for Catofin propane dehydrogenation reactor
The invention discloses a method for preparing a refractory material with a catalytic function for a Catofin propane dehydrogenation reactor. The method comprises the following steps: by taking a Catofin process waste aluminum-chromium catalyst as a treatment object and the waste aluminum-chromium catalyst as an additive, directly adding the waste catalyst into a Catofin propane dehydrogenation refractory material to prepare a refractory material with a catalytic function; through high-temperature firing, the catalyst which is coked and inactivated is partially activated, so that the catalyst becomes one part of the brick for the reactor, and the catalyst not only serves as a refractory lining and plays a role in heat insulation and heat preservation, but also can play a part of catalytic action; the refractory material with the catalytic function is prepared by introducing the waste catalyst, so that the waste aluminum-chromium catalyst is reactivated and utilized, and the overall catalytic treatment capacity of the reactor can be improved.
本发明公开了一种制备Catofin丙烷脱氢反应器催化功能耐火材料的方法。以Catofin工艺废弃铝铬催化剂作为处理对象，废弃铝铬催化剂作为添加物，将废弃催化剂直接加入Catofin丙烷脱氢耐火材料中，制备具有催化功能的耐火材料；通过高温烧成，将结焦失活的催化剂部分激活，使其成为反应器用砖的一部分，其不仅仅作为耐火衬里，起到隔热保温作用，还能够起到一部分催化作用；通过引入废弃催化剂制备具有催化功能的耐火材料，不仅将废弃的铝铬催化剂重新激活利用，还能提高反应器的整体催化处理能力。
