Macroporous alumina carrier and preparation method thereof
The invention discloses a macroporous alumina carrier and a preparation method thereof, and the catalyst carrier is prepared by the following steps: adding alumina as a matrix into an oil-in-water type oil-water emulsion prepared from deionized water, a pore-forming agent and a pore-forming auxiliary agent for pulping; the micro-emulsion drops in the oil-water emulsion are uniformly dispersed in the aluminum oxide slurry by stirring, and then macropores are formed in the aluminum oxide by quick drying and roasting. The use amount of the pore-forming agent is 1wt%-2wt% of the weight of aluminum oxide, the use amount of the pore-forming auxiliary agent is 0.15 wt%-0.25 wt% of the weight of aluminum oxide, and the macroporous aluminum oxide carrier is suitable for preparing a diesel distillate oil hydrogenation catalyst.
本发明公开了一种大孔氧化铝载体及其制备方法，该催化剂载体在制备过程中以氧化铝为基质，将其加计入到由去离子水、造孔剂和造孔助剂制备的水包油型油水乳液中进行打浆，通过搅拌使油水乳液中的微乳液滴在氧化铝浆液中均匀分散，然后经过快速干燥和焙烧在氧化铝中形成大孔。造孔剂的用量为氧化铝重量的1wt％～2wt％，造孔助剂的用量为氧化铝重量的0.15wt％～0.25wt％，本发明的大孔氧化铝载体适合于制备柴油馏分油加氢催化剂。
