摘要:
The invention relates to the use of ether vinyl hydrocarbyl homopolymers for increasing the effect of a cold flow improving agent with respect to combustible compounds and the use of an additive containing the same type polymer and an ordinary agent improving the cold flow in order to reduce the CFPP value( maximum temperature value of a gas oil filterability), thereby eventually reducing the CFPP 2 value and/or a suction value of a combustible compound.
摘要:
Ter-polymers are higher polymers comprising as structural units, units of formula I, units of formula II and units of either formula IIIa or formula IIIb:
and optionally and optionally, structural units of formula VII:
The polymers improve the low-temperature properties of fuel oils from petroleum sources and especially from vegetable or animal sources.
摘要:
The present invention is directed to a composition for use in a combustion engine either as a fuel additive or as an additive for a crankcase lubricant. The composition may include a polyunsaturated aliphatic or alicyclic compound having at least three, but no more than six, double bonds to improve the combustion process by acting as pseudo-catalyst in the combustion reaction. The compo sition may further include a derivative of dihydrobenzo-gamma-pyrane to improve the combustion process by acting as pseudo-catalyst in the combustion reaction. The composition may further include sufactants such as polyethylene glycol and/or one or more polyoxyalkene derivatives of either polypropylene glycol, polyethylene glycol or sorbitol. A media of fatty acid esters is provided to dilute the combustion promoters, surfactants and other ingredients allowing accurate concentrations of these ingredients to be introduced into the fuel chamber.

摘要:
A fuel oil composition comprises a fuel oil blend, at least one ethylene-vinyl ester polymer and at least one polyalkylmethacrylate polymer. The fuel oil blend comprises a middle-distillate fuel oil and a hydrotreated vegetable, animal or fish oil, wherein the amount of hydrotreated vegetable oil in the fuel oil blend is sufficient to provide the blend with an increase in the C 15 to C 20 n-alkane distribution of at least 3% by weight over the C 15 to C 20 n-alkane distribution of the middle-distillate alone.
