Title:
廃棄触媒からの触媒支持体の製造方法
Document Type and Number:
Japanese Patent JP2008525171
Kind Code:
A
Abstract:
A method of preparing, preferably recycling, a catalyst support material is disclosed and is particularly applicable to recycling a titania support. The invention includes crushing the used catalyst support that is obtained by leaching catalytic components from a used supported catalyst and preferably combining it with new catalyst support in order to provide the required average particle size and ratio of crystal phases. The invention has a number of benefits including making use of used catalyst support materials which have been conventionally disposed of and also providing a method to more efficiently recycle the active component. Where the support is recycled for a similar application, less promoter may be required.
