Abstract: The present application provides a treatment method and device for a waste plastic. A first aspect of the present application provides a treatment method for a waste plastic, including: firstly subjecting the waste plastic to a first pre-treatment to remove impurity and grease on a surface of the waste plastic, then subjecting the waste plastics to a second pre-treatment to convert a solid waste plastic into one in flow state; and finally, subjecting the waste plastic in flow state to a first cracking treatment and a second cracking treatment in sequence. Through the method provided in the present application, while cracking the waste plastic, chlorine element in the waste plastic may be removed by a multi-stage adsorption, which reduces chlorine content in the cracked oil, reduces pressure and burden in subsequent refining, and meets the limitation of the chlorine content in cracked products in downstream processes.

Abstract: The present invention relates to a method for the selective hydrogenation of an unsaturated compound, particularly a method in an unsaturated compound or a mixture containing unsaturated compounds for increase of the light sulphides weight, hydrogenation of a polyunsaturated compound and isomerization of a monounsaturated compound. The method uses a supported catalyst. The supported catalyst contains at least one Group VIB non-noble metal oxide and at least one Group VIII non-noble metal oxide deposited on a carrier; and the catalyst has an optimized acid distribution on the surface of the catalyst, and more preferably has an optimized Group VIII/VIB metal ratio and a Group VIII non-noble metal density per unit of catalyst surface area.
