||PCT/EP2014/002794||BIOCHEMTEX S.P.A.||BERNARDI, Marco|
It is disclosed a process for producing a low boiling mixture comprising ethylene glycol and propylene glycol from a liquid sugar stream derived from a ligno-cellulosic biomass feedstock. The liquid sugar stream is catalytically converted in the presence of hydrogen to a mixture, which is separated into at least a high boiling mixture, comprising glycerol, and the low boiling mixture. The high boiling mixture is converted to hydrogen
and the reforming hydrogen
is used in the catalytical steps. Preferably, all the hydrogen used in the conversion process is generated by aqueous phase reforming of the high boiling polyols mixture.

A system for hydrogen gas enhancement of hydrocarbon fuel combustion employs a closed electrolyzer vessel into which water is circulated, and an electrode plate assembly immersed in the vessel to dissociate water into hydrogen and oxygen gases. Only water is used as the electrolyte fluid without any additives. An air injector in the water return line injects air bubbling for enhanced dissociation of water in the electrode plate assembly. The electrode plate assembly is formed by one or more unit stacks of 7-plates each, including two outer cathode plates, a middle anode plate, and two spaced inner plates between each cathode plate and the anode plate. The generated hydrogen and oxygen gases are maintained in a stable condition in the output gas flow by an electromagnetic coil assembly that separates the hydrogen gas from oxygen gas. The system can obtain 180% reduction in hydrocarbon fuel usage in a vehicle engine, and 20 times reduction in carbon emission from vehicle exhaust. It can obtain a 500% increase in fuel usage efficiency in an electrical power generator operable on LPG fuel.
