Abstract
The objective of this work tends to promote methane content in biogas and evaluate sulfur dioxide emission from direct biogas combustion without desulfurization. Analytical results of biogas combustion showed that combustion of un-desulfurized biogas exhausted more than 92?% of SO2 (P < 0.01). In the meantime, more than 90?% of hydrogen sulfide was removed during the combustion process using un-desulfurized biogas (P < 0.01). Those disappeared hydrogen sulfide may deposit on the surfaces of power generator’s engines or burner heads of boilers. Some of them (4.6–9.1?% of H2S) were converted to SO2 in exhaust gas. Considering the impacts to human health and living environment, it is better to desulfurize biogas before any applications. ? 2014, Springer International Publishing Switzerland.
