Low-iron gas hardening fire clay for propane dehydrogenation reactor lining
The invention belongs to the technical field of refractory materials, and relates to low-iron gas hardening fire clay for a propane dehydrogenation reactor lining. The low-iron gas hardening fire clay for the propane dehydrogenation reactor lining comprises the following components: low-aluminum mullite powder, low-aluminum mullite powder, Guangxi white clay powder, sintered alumina powder, CMC (Carboxymethyl Cellulose), sodium borate and water glass. The CMC and the sodium borate are used as a reinforcing agent and a coagulation accelerator of the fire clay; and the water glass is a binding agent of the fire clay. The raw materials are good in uniformity and stability, the water absorption rate is stable, and the negative influence of the repeated oxidizing atmosphere-reducing atmosphere of the fire clay material on the fire clay cementation structure in the operation process of the reactor is reduced.
本发明属于耐火材料技术领域，涉及一种丙烷脱氢反应器衬里用低铁气硬性火泥。涉及的一种丙烷脱氢反应器衬里用低铁气硬性火泥的组成为：低铝莫来石粉、低铝莫来石粉、广西白泥粉、烧结氧化铝粉、外加CMC、外加硼酸钠、外加水玻璃；所述的CMC和硼酸钠作为火泥的增强剂和促凝剂；所述的水玻璃为火泥的结合剂。本发明原料的均一性和稳定性好，吸水率稳定，减少了火泥材料在反应器运行过程中周而复始的氧化气氛‑还原气氛对火泥胶结结构的负面影响。
