Title:
METHOD FOR PRODUCING AMMOXIDATION CATALYST, AND METHOD FOR PRODUCING ACRYLONITRILE
Document Type and Number:
WIPO Patent Application WO/2020/039985
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for producing an ammoxidation catalyst which enables synthesizing acrylonitrile with high yield. This method for producing an ammoxidation catalyst involves a preparation step for preparing a precursor slurry that will become the catalyst precursor, a drying step for drying the precursor slurry to obtain dry particles, and a firing step for firing the dry particles to obtain an ammoxidation catalyst, wherein the calorific value of the dried particles prior to firing, calculated from the area value of the exothermic peaks that have a maximum value in the range from 200°C to 300°C observed with TG-DTA measurement, is 45-200 J/g.
