A high-efficient conversion of dimethyl ether (DME) to diesel fuel additive
s at ambient condition via dielectric-barrier discharges has been performed
. The conversion of DME reaches a high value of 66.56% at a gas flow rate o
f 30 mL.min(-1). The liquid obtained is a cetane number promoter of diesel
fuels. The selectivity of liquid product is more than 40%.
