Title:
CATALYST FOR ACRYLONITRILE SYNTHESIS, METHOD FOR PRODUCING CATALYST FOR ACRYLONITRILE SYNTHESIS, AND METHOD FOR PRODUCING ACRYLONITRILE
Document Type and Number:
WIPO Patent Application WO/2020/184330
Kind Code:
A1
Abstract:
A catalyst for acrylonitrile synthesis, which contains a composite body of a metal oxide and a silica that supports the metal oxide, and which is configured such that the ratio of the specific surface area B of the catalyst for acrylonitrile synthesis after the acceleration test described below to the specific surface area A of the catalyst for acrylonitrile synthesis is from 0% to 60% (inclusive), said ratio being expressed by 100 × (A – B)/A. (Acceleration test): The catalyst for acrylonitrile synthesis is heated in the air at 650°C for 10 hours.
