Abstract
A method of manufacturing a solid acid catalyst using industrial waste such as an insulator, optical fiber, and tip material is provided. The raw material contains a template agent, a compound having a formula of RCOR, where Rand Rare alkyl groups, a silicon-containing inorganic compound, an aluminum-containing inorganic compound, and water with a weight ratio of SiO/AlOof at least 1,000. The raw material is heat treated in a closed chamber (a first heat treatment), and heat treated in an atmosphere containing oxygen (a second heat treatment).
