Bio-DME (dimethylether produced from biomass, to be used as biofuel
Bio-DME (dimethylether produced from biomass, to be used as biofuel)
The invention utilizes the fumigant method by combining two gases (DME and propane) which autoignite prior to the injection of the liquid diesel fuel.
The bed preferentially adsorbs propylene and dimethylether from the mixture.
One example of such a system is isopentane and dimethylether.
Alternatively, the methanol (12) can also be converted to dimethylether (18) as diesel fuel.
(e) "biodimethylether": dimethylether produced from biomass, to be used as biofuel;
biodimethylether’: dimethylether produced from biomass, to be used as biofuel;
