Product description

Hydrogen production and its utilization, as fuel or for energy production, seems to be a promising way to minimize the actual dependence on fossil fuels. Thus, the energetic transition should be based on green energy production in order to solve the greater concerns; environmental pollution and guaranteed availability. In this sense, the use of bio-renewable organic sources such as polyalcohols, in an intensified process through the use of a micro reactor seems to be a promising and sustainable alternative.
We developed a fuel processor system for the hydrogen production from Ethylene glycol for a fuel cell system designed for the power supply of aircrafts.
Ethylene glycol (EG) can be produced directly and efficiently via catalytic hydrogenation of cellulose or cellulosic biomass derived oxygenated compounds. Cellulose, as the most abundant component of biomass (accounting for 35-50%), is being considered as a promising alternative to fossil resources. Another EG production route is based on the bio-oil obtaining through the pyrolysis of the biomass. Departing from this bio-oil and after the water addition, a water soluble fraction of biomass pyrolysis liquid can be obtained (around 20% of organics and 80% water), mostly composed by acetone, ethylene glycol and acetic acid.
