Problems solved by technology

However, since the binder itself has no catalytic activity, the original catalytic activity will be greatly reduced due to the binder covering the surface of the solid acid
In addition, the material of the adhesive has insufficient chemical resistance, and it is assumed that the durability in industrial continuous use is insufficient.
[0008] Therefore, when using a binder to obtain a molded solid acid, a new preparation method is required to solve the problems of low catalyst activity when using a binder and deterioration of the binder itself.

preparation example Construction

[0060] The molded solid acid produced by the production methods illustrated and described in detail so far has a relatively high degree of freedom in the blending ratio of the wood raw material powder or in the design of the shape. Therefore, they can be prepared separately according to the desired use and purpose. In particular, since the solid acid is formed into a molded product of a predetermined shape, separation and recovery after use in a catalytic reaction become easy, and the usability at the time of use is greatly improved.

[0061] The present invention is characterized in that the binder contained in the molded solid acid is a synthetic resin, and finally the binder and the wood raw material powder are heat-treated simultaneously. The bonding of various raw materials to each other is promoted by heat treatment. Needless to say, the binder used in the molded solid acid of the present invention does not have the property of finally binding and integrating powdered s...

Abstract

To provide a molded solid acid production method in which costs can be reduced by using a woody raw material, and in which by heat treating the woody raw material together with a synthetic resin binder, a deterioration in catalyst performance caused by being coated with a binder is prevented, the degree of freedom in terms of shape design is high and the molded solid acid has an appropriate hardness. A synthetic resin binder-molded solid acid production method has the following: a raw material kneading step (S10) in which a kneaded woody raw material product is obtained by kneading a woody raw material powder (M) with a synthetic resin binder (B); a molding step (S20) in which a raw material molded body is obtained by molding the kneaded woody raw material product into a prescribed shape; a heat treatment step (S30) in which a heat treated molded body is obtained by subjecting the raw material molded body to heat treatment in an inert atmosphere; and a sulfonation step (S40) in which a molded solid acid is obtained by introducing sulfo groups into the heat treated molded body.

Description

technical field [0001] The present invention relates to a synthetic resin binder molded solid acid and a preparation method thereof, in particular to a solid acid in which a sulfo group (sulfonic acid group) is introduced into a molded body molded into a predetermined shape by a synthetic resin binder and the solid acid Preparation. Background technique [0002] Sulfuric acid is also widely used as a catalyst for reacting hydrocarbon compounds because of its high activity. For example, it is used for the following purposes: to promote the esterification reaction of free higher fatty acids and alcohols to obtain higher fatty acid esters, to promote the hydrolysis reaction from sugar chains such as cellulose to monosaccharides, and to promote the alkylation reaction of synthetic hydrocarbon fuels, etc. . [0003] Sulfuric acid is consumed every time after being neutralized, washed, and used as a catalyst to help promote various reactions. Since sulfuric acid is liquid, it i...
