Solar-driven pyrolysis and gasification of low-grade carbonaceous materials

Solar-driven experiments showed that H2 and CO evolved as important product gases demonstrating the high quality of syngas production for the three feedstocks. Straw is the more suitable feedstock for solar-driven processes due to the high gas production yields. Comparing the solar-driven experiments, gasification generates higher percentage of syngas (mix of CO and H2) respect to total gas produced (sum of H2, CO, CO2 and CH4) than pyrolysis. Thus, solar-driven gasification generates better quality of syngas production than pyrolysis.
