Abstract

Abstract: The nature and the origin of organic residues, present in spent catalysts afterisobutane/1-butene alkylation, have been studied by combined TG-DSC, UV-VIS, FT-IR techniques. Two kinds of organic compounds are present: high molecular weight unsaturated byproducts, responsible of pore blockage, and light hydrocarbons, such as alkylates and small oligomers, entrapped in the catalysts. The latter desorb in inert gas flow at medium-low temperature, whereas the former must burned off in order to regenerate the catalyst.
