Virgin polymers via pyrolysis ? A review of heteroatom removal options
Original language description
This review is dedicated to the removal of heteroatoms from plastic pyrolysis liquid products for use in thepetrochemical industry. The chapters are devoted to removing individual groups of heteroatoms and summarizingthe current scientific knowledge on the subject. Attention is given to the possibilities of heteroatomremoval at all stages of the recycling process except sorting. Most of the findings in this area relates to thehalogen removal, where high efficiencies can be achieved already in the pyrolysis process. In contrast, theremoval of other heteroatoms has mainly been studied in the liquid product, usually in a hydrogen atmosphereand in the presence of a catalyst. It seems economically feasible to remove the heteroatoms as early as possible inthe recycling process. This can be achieved in part by washing the waste plastic in water, which can remove alarge proportion of the heteroatoms present as impurities. The work highlights the need for comprehensivemapping of heteroatoms in products and, in many cases, the need for more data regarding their removal. Finally,conclusions are drawn for further research in this area.
