This disclosure describes a method for regenerating a semi-regenerated reforming catalyst. The method comprises adjusting the reaction temperature to 250-480 C., introducing a sulfur-containing naphtha into the reforming reactor, or stopping introducing a feedstock into the reforming reactor, and introducing a sulfur-containing hydrogen into a recycle gas, until the sulfur content in the catalyst is 0.32-0.8 mass %, then the catalyst is subject to coke-burning, oxychlorination and reduction. Alternatively, the method first subjects the spent catalyst to coke-burning followed by introducing sulfate ions thereinto; and then performing oxychlorination and reduction. Disclosed is still another method for regenerating a platinum-rhenium reforming catalyst, which comprises coke-burning the spent catalyst; introducing sulfur and chlorine in the catalyst by impregnation; and then drying, calcinating and reducing.

For depolymerization of a cured epoxy resin material, used is a composition including a transition metal salt or a transition metal oxide containing a transition metal element (metal element that belongs to Groups 3-12 in the Periodic Table). In the reaction solvent, an oxidation occurs by the medium of the transition metal element so that the cured epoxy resin material may be depolymerized and decomposed. In this manner, it is possible to carry out depolymerization of a cured epoxy resin material at a temperature of 200 C., specifically 100 C. or lower very simply and rapidly, and to reduce the processing cost and energy requirement.
