Title:
レニウムおよびアルミニウムを含む担持触媒、その調製方法およびオレフィンのメタセシスへの適用
Document Type and Number:
Japanese Patent JP4189698
Kind Code:
B2
Abstract:
A catalyst contains at least a porous inorganic support, 0.01-20 wt.% of rhenium in oxide form and 0.01-10 wt.% of aluminium derived from an aluminium compound of formula (RO)qAIR'r, in which R is an alkyl group containing 1-40 C, R' is also an alkyl group containing 1-20 C, q and r = 1 or 2 and q+s = 3. The preparation of the catalyst involves: (a) preparation of a calcined catalyst precursor containing at least an inorganic porous support and rhenium. (b) contacting the precursor with a compound of formula (RO)qAIR'r obtained from reaction between ROH and AIR'3 ; and (c) drying the resulting product. Also claimed is the metathesis of olefins using the above catalyst carried out in gas phase at 0-100 degrees C.
