Research output: Chapter in Book/Report/Conference proceedingConference contribution


The cracking of the waxes obtained in the flash pyrolysis of polypropylene has been studied under standard conditions in FCC (Fluid Catalytic Cracking) units. The reaction equipment is provided with a Riser Simulator Reactor and the experiments have been carried out using a commercial catalyst equilibrated in a refinery, with a catalyst/fed ratio of C/O= 5.5, in the 500-550°C range and for contact times between 3 and 12 s. The effect of these operating conditions on the yields of products and on the composition of gas and gasoline lumps has been studied. The results have been compared with those of VGO (Vacuum Gas Oil) cracking, which is the standard FCC feed in refineries.
