METHOD OF PREPARING CATALYST SUPPORT FROM A WASTE CATALYST |
摘要 |
<p>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.</p> |
