- Abstract
Traditional liquid fuel, such as kerosene, is still the primary fuel in air transport for longer distances. Other types of propulsion, like electric batteries, fuel cells, or their combination with solar panels, are only practical for smaller aeroplanes designed for transportation purposes. In order to replace at least some fossil kerosene with waste raw materials, kerosene production from waste polyalkenes has become more important. This work investigates the possibility of using a laboratory continuous conical spouted bed reactor for the study of the production of jet fuel fraction from waste polypropylene. Optimal reaction conditions of cracking for producing high yields of hydrocarbon liquids were determined. Tested pyrolysis temperatures changed from 420 to 460°C, and CO2 flow from 0.05 to 0.2 L.min-1 at various polypropylene dosing speeds. Yields and composition of liquid and gaseous products were measured. Monomer propene dominated with almost 60 wt% in pyrolysis gases. The highest yield of jet fuel fraction, 34 wt%, was obtained at 420°C and 0.1 L.min-1 of inert gas flow.
