摘要:
The present invention relates to the use of 1,1-diethoxyethane for increasing the knocking resistance of low-boiling gasoline with an initial boiling point (IBP) of 80°C to 120°C by at least 40 units (research octane number).
摘要:
A gasoline product containing a combustion improver and a manufacturing method therefor. A combustion improver is added to gasoline to reduce an ignition point of the gasoline, so that the gasoline product can be applied to a compression ignition engine. Content of the combustion improver is controlled according to a value of octane in base gasoline, so as to implement homogeneity of a nitrogen oxygen equivalent contained in the gasoline product. The combustion improver is selected from at least one of ammonium nitrate and a derivative thereof, nitric acid ester and a derivative thereof, aniline and a derivative thereof, and nitrobenzene and a derivative thereof.

摘要:
For producing synthetic fuels, an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, is converted to olefins on a catalyst in a first process stage, and this olefin mixture then is divided in a separating means into a stream rich in C1-C4 hydrocarbons and a stream rich in C5+ hydrcarbons. The stream rich in C5+ hydrocarbons is divided into a stream rich in C5 and C6 hydrocarbons and a stream rich in C7+ hydrocarbons, wherein the stream rich in C5 and C6 hydrocarbons is at least partly subjected to an etherification with methanol. The ethers thus obtained are admixed to the gasoline product stream.
摘要:
A fuel additive cartridge for use with a dimethyl-ether fuel system of a vehicle includes a reservoir for storing and dispensing a liquid fuel additive into a flow of fuel in a fill conduit during refueling. The cartridge also includes a dispenser actuated by the fuel flow to selectively dispense the liquid fuel additive from the reservoir. The fuel additive cartridge is intended to attach to a dimethyl-ether fuel system at a location between a fueling inlet connector and a storage tank to facilitate a metered mixing of liquid fuel additive from the cartridge and dimethyl-ether during the re-fueling of the storage tank.
摘要:
The present disclosure provides a diesel fuel composition containing DMC and multifunctional additives to reduce particulate emission, improve efficiency and be used in cold and/or hypoxia conditions.
摘要:
The invention provides (a) a diesel fuel formulation containing a triethoxypropane and a palm oil methyl ester (POME), and (b) a diesel fuel supplement containing a premix of a triethoxypropane and a POME. The triethoxypropane may be 1, 2, 3-triethoxypropane or 1,1,3- triethoxypropane. Also provided is a process for preparing the formulation, and its use in an internal combustion engine. A triethoxypropane may be used, in a POME or in a diesel fuel formulation containing a POME, to stabilise a glyceride, in particular a saturated monoglyceride. It may also be used to reduce the cloud point of a POME or of a POME-containing diesel fuel formulation, by an amount greater than conventional theory would have predicted to be possible.
