| titleOfInvention | A kind of HFA 134a catalytic pyrolysis generates the catalyst and in situ regeneration method of trifluoro-ethylene |
| abstract | The present invention provides one kind 1,1,1,2- tetrafluoroethane catalytic pyrolysis generates the catalyst and in situ regeneration method of trifluoro-ethylene, it contains any one or a few mixture in the aluminum fluoride of OH groups, the P doping aluminum fluorides containing OH groups or zinc doping aluminum fluoride containing OH groups, and the molar ratio of P/Zn and Al is 0 ~ 1 in catalyst:1, the demand of industrialized production can be reached after catalyst life and in-situ regeneration.The catalyst that the present invention uses is with the aluminum fluoride containing OH groups, fluorination phosphorus aluminium and fluorination zinc-aluminium, it is desirable that catalyst has higher specific surface, the wherein at least one such as auxiliary agent Ni, Pd, Ru, Pt, La, Sm, K, Fe, Zn, Zr, Ce.Preparation method can be sol-gal process and template, fluoride post treatment method.Catalyst of the present invention has a longer life expectancy, and can be activated by being passed through vapor, makes the activation recovering of catalyst to 90% or more, the catalyst life of primary recycling is 90% or more fresh catalyst. |
