Method and device for regulating waste organic polymer material pyrolysis products

A method for regulating a waste organic polymer material pyrolysis product, comprising the following steps:

• (1) uniformly mixing a waste organic polymer material with a composite auxiliary agent for removing a harmful element in a waste organic polymer material to composite auxiliary agent mass ratio of 90:10 to obtain a mixture;
• (2) conducting a layered arrangement with a catalyst in an upper layer of a pyrolysis reactor and the mixture of the waste organic polymer material and the composite auxiliary agent in a lower layer of the pyrolysis reactor, ensuring that materials in the upper layer and the lower layer move in opposite directions to maintain a countercurrent flow;
• and
• (3) conducting a pyrolysis process in the pyrolysis reactor by placing the mixture of the waste organic polymer material and the composite auxiliary agent in the lower layer of the pyrolysis reactor under a waste organic polymer material pyrolysis temperature of 400-450° C. allowing the waste organic polymer material to decompose into a primary pyrolysis product, thereafter allowing the primary pyrolysis product, after reacting with the composite auxiliary agent for removing the harmful element, being transported to the upper layer of the pyrolysis reactor to fully contact the catalyst, and placing under a product regulation temperature of 550-800° C. in the upper layer of the pyrolysis reactor, resulting in a final pyrolysis product comprising aromatics;
• wherein the catalyst is one or a mixture selected from a refinery waste catalyst, a fly ash, and a red mud, and the composite auxiliary agent for removing the harmful element is an alkaline component comprising the red mud.
