Pseudo-boehmite

Pseudo-boehmite bụ ihe kacha mma n'oge mmepụta gamma alumina, n'ihi na naanị iwepụ mmiri site na calcination na ihe dị ka 447 C ka achọrọ. Njikwa nke mgbanwe ọrụ n'oge mmepụta nke pseudo-boehmite: supersaturation nke ngwọta bụ ihe dị mkpa pụrụ iche, yana pH, okpomọkụ, adịghị ọcha na ọdịdị nke reagents [3,4]. Hụ na ịdị ọcha nke ihe a na mgbanwe ndị a na-ekpebi ọdịdị, udidi na nhazi ya nke precipitate. Ya mere, ọ dị mkpa ịgbaso ihe ndị na-eme n'oge mmepụta, iji buru amụma mmepụta na ịdị mma nke ngwaahịa ikpeazụ. N'ọrụ a, e mepụtara njikọ nke pseudo-boehmite site na usoro mmiri ozuzo, site na iji ngwọta aluminom sulfate supersaturated na ammonium hydroxide concentrated (28%) dị ka reactants; e mere ka usoro a mara mma ka ọ na-ebelata okpomọkụ mmeghachi omume n'okpuru ebe esi nke amonia. E ruru njikwa okpomọkụ nke reactant media site na inweta data na njikwa akpaka nke reactant media. Egosiri na ịrụ ọrụ na ọnọdụ atisothermal reactor na-eme ka mma ikpeazụ nke pseudo-boehmite emepụtara.
