Abstract
Official abstract text for this publication.
An object of the present invention is to provide titanium oxide granules that have a novel structure and have a characteristic of highly efficient decomposing capability, and a method of decomposing plastic and organic waste by using the granules. The present invention has been completed based on the finding that a method of decomposing plastic waste by using titanium oxide granules having a transition metal and/or a transition metal oxide, in particular copper, supported thereon enables decomposition of plastic waste at extremely high efficiency in a low-temperature region for a long period of time as compared to methods of decomposing plastic waste by using the related-art titanium oxide granules.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst for decomposing plastic and organic waste, comprising titanium oxide granules having a transition metal and/or a transition metal oxide supported thereon and containing titanium oxide as an active component, wherein the catalyst has the following characteristics: (1) the granules each have a substantially spherical shape; (2) granules each having a particle diameter of from 0.2 mm to 1.6 mm account for 70% or more of all the granules; (3…
