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
