Title:
流動触媒のためにアルミナを解膠するプロセス
Document Type and Number:
Japanese Patent JP7064484
Kind Code:
B2
Abstract:
A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprising mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt %. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.
