摘要
笔者以经盐酸预处理后的煤矸石为主要原料,活性炭为造孔剂,采用挤压成形法制备煤矸石基催化剂载体,确定合理的原料配比和烧结制度,研究造孔剂添加量对催化剂载体气孔率、吸水率的影响。研究结果表明:煤矸石与苏州土配比为8∶2,烧成温度为1040℃,造孔剂活性炭添加量为35%的条件下,制备出的催化剂载体气孔率达到49.2%,催化剂载体的主要矿物相为莫来石和方石英;SEM结果显示:催化剂载体内部形成了骨架结构和贯通气孔。
Coal gangue based catalyst carrier was prepared by extrusion molding method,using coal gangue as the main material and active carbon as the pore former.The effects of the pore former on catalyst carrier porosity and water absorption were studied at a certain ratio of the raw materials and sintering conditions.The results showed that the highest porosity of the catalyst carrier was 49.2%,with the ratio of coal gangue and Suzhou soil of 8∶2,the sintering temperature of 1040℃,and the active carbon addition percentage of 35%.The main mineral phase was confirmed mullite and cristobalite.According to the results of SEM characterization,a skeleton structure and penetrating pores were formed inside the catalyst carrier.
