Abstract
This article proposes structural and technological approaches for a hybrid heliothermal pyrolysis unit designed for the efficient utilization of biomass and hydrocarbon-containing wastes. The study demonstrates the effectiveness of intensifying biomass pyrolysis by transferring high-temperature heat obtained from a parabolic trough solar concentrator to the steam jacket of a tubular pyrolysis reactor. A heliothermal approach to the production of alternative fuels from agricultural residues is presented, including pyrolysis gas, pyrolysis liquid, and biochar. In addition, a method for obtaining gaseous products (ethylene, propylene, and butylenes) from pyrolysis liquid is proposed. Experimental results show that within the temperature range of 250–450 °C, heliopyrolysis of plant biomass enables the production of gaseous, liquid, and solid fuels with high yields. The proposed method and technology are effective in terms of energy savings, environmental safety, and reduction of CO2 emissions, and they represent a promising direction in the production of alternative fuels.
