Annotation. Introduction. The article presents the results of a thermal-technological regime study of the pyrolysis process of sunflower plant waste in a parabolic solar concentrator heliopyrolysis device. An experimental parabolic solar concentrator heliopyrolysis device was created to investigate the heliopyrolysis process. In the process of thermally processing sunflower plant waste, the dependency of the resulting products on temperature and the material balance were studied in experiments. In experiments conducted with the device, the pyrolysis of 1 kg of sunflower plant waste loaded into the heliopyrolysis reactor resulted in the production of 63% biochar, 10% liquid, and 27% gaseous fuels.
Methods and Materials. The material balance of biofuels separated from the biomass loaded into the parabolic solar concentrator heliopyrolysis reactor was carried out in laboratory conditions with an initial moisture content of 10% and a size of 6-8 mm. The studies were conducted on sunflower plant waste.
Results. According to the experiments conducted, it was found that the total yield of pyrolysis products varies little within the temperature range of 350-400°C. Thus, the pyrolysis of 1 kg of sunflower plant waste loaded into the experiment resulted in the production of 63% biochar, 10% liquid, and 27% gaseous fuels.
Conclusion. The developed parabolic solar concentrator heliopyrolysis device allows the use of solar heat to cover the energy needed for conducting cycles during daylight hours. Experimental studies carried out with the parabolic solar concentrator heliopyrolysis device revealed that it is possible to obtain solid, liquid, and gaseous fuel samples from the pyrolysis of sunflower plant waste.
