Opportunities of Pseudoboehmite Processing from Aluminum Content Raw Material at Sintering Method

Abstract

Technology for processing aluminum raw materials derived from the sintering method enables produce the aluminum hydroxide in the form of pseudoboehmite directly in the production cycle from processing aluminate liquors. Pseudoboehmite was prepared by carbonation. Pseudoboehmite dewatering capacity was of 20–200 kg/h m2. Studies on the properties of carbonation pseudoboehmite showed that its properties are similar to the same product obtained in other ways. At the same time, pseudoboehmite from aluminate liquors has lower specific surface area, includes other modifications of aluminum hydroxide, and other features. The dried pseudoboehmite under normal conditions has a high porosity, and can be used in the matrix for the zeolite Y containing hydrocarbon conversion catalyst to produce a catalyst of suitable attrition resistance and catalytic activity for use in fluid cracking systems etc.
