Olefina arinen ekoizpena hondakin plastikoetatik

Abstract

In this paper two strategies focused on the production of light olefins from polyolefins are compared. In both cases, the first stage consists in the plastics pyrolysis in a conical spouted bed reactor. With respect to the second stage, two different alternatives have been studied to perform the in-line cracking of the volatiles formed in pyrolysis. In the first alternative, a HZSM-5 catalyst is placed in a fixed bed reactor to perform the catalytic cracking, while in the second one a multitubular reactor is used for the high temperature thermal cracking.
