Title:
PSEUDOBOEHMITE, AND MANUFACTURING METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/135714
Kind Code:
A1
Abstract:
Provided is a pseudoboehmite, which has a dry basis content of 55-85wt%, includes phosphate groups, and has a sodium oxide content not greater than 0.5wt% and a phosphorus content as phosphorus pentoxide of 1.2-5.7wt%, relative to the pseudoboehmite total weight 100wt%. The present pseudoboehmite has advantages such as a very low sodium content. Also provided are a manufacturing method for the pseudoboehmite, and an application of the pseudoboehmite in aluminium oxide manufacturing, hydrogenation catalyst manufacturing and oil hydrogenation.
