Influence of pyrolysis oil from plastics on product structure in fluid catalytic cracking

Original language description

The chemical recycling is currently a very hot topic. In this respect, the possibility of using oils from the pyrolysis of waste plastics for petrochemical production is often discussed and studied. The most problematic from this point of view is the processing of the distillation fraction above 280 °C. One option is to use this fraction as a component for co-processing on fluid catalytic cracking (FCC) technology. However, some specific properties of this alternative component could be very problematic. In particular the content of nitrogen, oxygen and polyaromatics compounds. This can have a negative effect on the yields as well as life cycle of the FCC catalyst. Therefore, the aim of this work was to determine the effect of adding pyrolysis oil to the standard feedstock in the level of 10 and 20 wt%. The comparison of the obtained yield structures was performed in the laboratory scale using the ACE® R+MM unit. The possibility of eliminating the negative properties of pyrolysis oil was also tested. The addition of hydrocracked vacuum distillate (HCVD) was studied for this purpose. The negative effect of the addition of pyrolysis fraction on the yields of the required product was confirmed. On the other hand, a very positive role of HCVD addition was found. This fact can help process of problematic materials, especially from the economic point of view.
