Hydrous Ethanol

Hydrous-ethanol is reformed to hydrogen-rich mixture gas which is an excellent fuel for engines. The advantages of this approach are that fossil fuel consumption and CO2 emissions are reduced, and the waste heat from engine exhaust can be used as energy source for hydrous-ethanol evaporating and reforming. The experiment is carried out on a gasoline engine as primary engine with only modest changes. The results indicate that the hydrogen-rich mixture gas allows operation at much higher compression ratio due to its intrinsic octane number which could contribute to the power performance, and the NOx, CO, THC emissions are reduced remarkably because of lean combustion realized in the cylinder.

Abstract This study synthesizes biogas with low methane contents (<50%) to hydrocarbons that form a combustible synthesis gas (syngas) mixture. Conventional methods used for reforming biogas has limitations in terms of fabrication, maintenance, and cost. This is especially true when the biogas’ composition fluctuates. Non-thermal plasma (NTP) is an alternative method to produce combustible syngas for power generation. Thus, the exhaust emissions from a 2 kWe spark ignition (SI) engine fuelled with gasoline and NTP-synthesized biogas is investigated with respect to the type of NTP reactor, plasma power consumption and biogas composition. Two types of NTP reactors are used: a cylindrical reactor where the gas flow path is linear, and a cyclonic reactor where the gas flow path is a curvature, similar to that of a gas-solid cyclone separator. The results show that the NTP reactors produced additional hydrocarbons, decreasing flue gas temperatures by 4°C and reducing NOx emissions by 35%.
