Method for Producing Relating to Industrial Mass Production of High-Purity Artificial Zeolite
20220363555 · 2022-11-17 ·

A high-purity artificial zeolite is industrially mass produced by carrying out osmosis treatment of fly ash in an alkaline aqueous solution, subsequently carrying out the osmosis treatment again with an acidic aqueous solution of pH 1.0 or less obtained by adding acid to the osmotic aqueous solution of fly ash, then performing solid-liquid separation while water wash and dewatering in a centrifuge, thereby synthesizing a starting composition, and performing hydrothermal reaction treatment to this starting composition.

PARTICULATE INORGANIC MATERIAL FOR HYDROLYSIS OF BIOMASS MATERIALS AND METHODS
20180044596 · 2018-02-15 ·

A composition comprising an inorganic particulate material adapted to convert a biomass material into hydrolysis products is provided. The inorganic particulate material comprises at least 0.1 wt. % of at least one impurity in its crystal structure based on the total weight of the inorganic particulate material. Methods of convert a biomass material into hydrolysis products using the compositions comprising an inorganic particulate material are also provided.
