REGENERATION OF NOBLE METAL CATALYSTS USING FLUOROHALOCARBONS OR FLUOROHALOHYDROCARBONS |
摘要 |
This invention provides a process for the regeneration and/or activation of a noble catalyst comprising contacting said catalyst with an atmosphere comprising a fluorohalocarbon and/or a fluorohydrocarbon of the formula, CnHmFpXq, wherein X is chlorine and/or bromine; n is an integer from 1 to 6; m is an integer from 0 to 6, provided that m can be no more than the total n in the compound; p and q are integers from 1-13 when the compound is acrylic and integers from 1-11 when the compound is cyclic, provided that the fluorohalocarbon and/or fluorohalohydrocarbon always contain at least one chlorine or bromine atom and provided that m+p+q=2n+2 when the compound is acrylic and that m+p+q=2n when the compound is cyclic, at a temperature in excess of 200 DEG C. |
