摘要: 以氢氧化铝直接快速脱水为原料制备蒽醌降解物再生新型催化剂。运用表面原位生长技术,采用固体碱与催化剂掺杂复配技术,制备出了孔容≥0.55 mL/g、比表面积≥180 m2/g、再生活性≥5 g/L、使用寿命≥90 d的条状蒽醌降解物再生新型催化剂。表面原位生长技术有利于氧化铝一次粒子长大,增大间隙孔,从而制备出大孔容、高比表面积的活性氧化铝;固体碱与催化剂掺杂可以强化碱性活性组分与载体的相互作用,避免碱液活性组分的快速流失,从而大大提高新型催化剂的活性和使用寿命。

Abstract: New regeneration catalyst for anthraquinone degradation products was prepared by direct rapid dehydration method and with aluminum hydroxide as raw material.Using the surface in situ growth technology and adopting solid alkali-and-catalyst doping-and-compounding technology,new extruded regenerating catalyst for anthraquinone degradation products with pore volume≥0.55 mL/g,surface areas≥180 m2/g,regeneration activity≥5 g/L,and service life≥90 d was prepared.The surface in situ growth technology was favorable for the growth of primary particles of alumina and for increasing mesopore of it,so as to prepare active alumina with larger pore volume and higher surface area;solid alkali and catalyst doping could strengthen the interaction between the active component and the carrier,to avoid the rapid loss of the active component,thus greatly improve the activity and service life of new catalyst.
