a value chain is a series of events that takes a raw material and with each step adds value to it. global interest in the application of natural gas (ng) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. many technological solutions are currently considered on the market or in development, whic...

using surface analysis, simultaneous effects of temperature (260-380ºc) and ethanol concentration (0-1%) on dimethyl ether (dme) selectivity, yields of hydrocarbon and dme, and methanol conversion were investigated in methanol dehydration reaction over γ-al2o3 catalyst. methanol conversion and yield of hydrocarbon/dme were found to be significantly affected by temperature and the temperature-et...

The impacts of different fuel injection timings (base (15BTDC) and retarded (12BTDC)) on a single cylinder common rail direct (CRDI) compression ignition (CI) engine under dual mode (DME-diesel) was examined at the maximum torque with speed 2200 rpm. diesel (liquid) directly injected into engine’s end stroke Dimethyl ether (gas) intake system during suction stroke. DME energy share (DME ES) b...

The depletion of fossil energy sources and the legislation regarding emission control demand use alternative fuels rapid progression aftertreatment technologies. study dimethyl ether (DME) catalytic oxidation is important in this respect, as DME a promising clean fuel at same time VOC pollutant present tail gases industrial processes. In work, copper ferrite catalysts synthesized via citrate co...

The direct synthesis of dimethyl ether (DME) on bifunctional catalysts is highly attractive for valorizing CO2 and syngas derived from biomass gasification a key process to reduce greenhouse gas emissions. DME economy (conventionally based its use as fuel) arouses growing interest, in parallel with the development different routes conversion into hydrocarbons (fuels chemicals) H2 production. Th...

In the present work, renewable oxygenates 2,5-dimethylfuran (DMF) and dimethyl ether (DME) are considered as alternatives to fossil fuels for gasoline engines. The effects of blending DMF DME on combustion surrogate numerically studied. is toluene primary reference fuel (TPRF) mixtures containing iso-octane, n-heptane, toluene. Two skeletal mechanisms proposed analysis: mechanism A with 504 spe...
