Study of the slow batch pyrolysis of mixtures of plastics, tyres and forestry biomass wastes. Effect of experimental conditions in the liguid compounds
In this work was studied the effect of experimental conditions in the production of liquid
compounds from slow batch pyrolysis of mixtures of plastics, tires and pines wastes. The major
compounds formed were toluene, ethylbenzene, and linear alkanes from C5 to C10 (each reaching
yields around 5% w/w of the initial waste mixture). The pyrolysis reaction time and temperature
improved the production of those species, while decreasing heavier alkanes formation. An increase
of plastics content in waste mixture seemed to favour the production of lighter alkanes, although
this effect was not as notorious as the ones just mentioned. The styrene production decreased
regularly with the decrease of tyres content in the mixture. Autoclave initial pressure variation did
not seem to affect significantly the formation of the major compounds
