Abstract
Official abstract text for this publication.
A method of preparing a catalyst using an alkali metal or an alkaline earth metal in natural cellulose fibers as a co-catalyst and a dispersant. The catalyst is prepared using an alkali metal or an alkaline earth metal as a co-catalyst and a dispersant, thus increasing the dispersibility of catalytic components and enhancing the interactions between the catalyst and the support to thereby retard agglomeration and increase the durability of the catalyst.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of preparing a catalyst using an alkali metal or an alkaline earth metal inherently contained within natural cellulose fibers, and without the artificial addition of the alkali metal or the alkaline earth metal, such that the alkali metal or alkaline earth metal inherently contained within the natural cellulose fibers is a co-catalyst and a dispersant, the method of preparing the catalyst comprising: thermally treating natural cellulose fibers to re…
