Abstract
The invention relates to a novel diesel oil anticoagulant, belonging to the technical field of fuel oil additive. The novel diesel oil anticoagulant is a dustless and non-corrosive macromolecular polymer which can prevent paraffin crystals in diesel oil from forming a three-dimensional network structure as a result of temperature reduction. After the diesel oil anticoagulant is added to a high-inductance oil solution according to a certain ratio, the condensation point can be reduced by 15-35 DEG C.
Description
Technical field
The present invention relates to a kind of novel diesel oil anticoagulant, belong to the fuel oil additive technical field.Novel diesel oil anticoagulant involved in the present invention is a kind of ash-free, non-corrosive high polymer, can prevent because the paraffin crystal that temperature reduces in the diesel oil that causes forms tridimensional network.Under the good situation of finish irritability, add diesel pour inhibitor involved in the present invention in proportion after, condensation point can reduce 15-35 ℃.
Background technology
Condensation point and cold filter clogging temperature are the important indicators that characterizes the diesel oil at low-temperature use properties.Condensation point (SP) is the top temperature that shows that diesel oil loses flowability in low temperature environment; Cold filter clogging temperature (CFPP) can cause filter screen to stop up in the time of then can showing diesel oil by diesel engine oil supply system top temperature.For solar oil, cold filter clogging temperature seems more important in actual use than condensation point index.This is because cold filter clogging temperature is directly related with the low temperature use properties of diesel oil, and condensation point mainly is relevant with storage, the transportation of diesel oil.
Why diesel oil solidifies at a lower temperature, is that when temperature reduced, these waxes can be separated out gradually owing to contain a certain amount of wax (being normal paraffin) in the diesel oil, and forms the wax crystalline substance.Along with the further reduction of temperature, the wax crystalline substance can be grown up rapidly, at first forms plane crystallization, and these crystallizations interconnect, so that form tridimensional network, oil is wrapped in wherein, it is lost flowability and presents curdled appearance.
Usually the normal paraffin content in the diesel oil is about 15%-30%, when diesel oil is cooled, as long as the normal paraffin about 2% is arranged separates out, diesel oil is solidified, and the diesel oil wax amount of analysing at a certain temperature depends on the processing scheme and the harmonic proportion of each distillate of crude oil type, boiling range and the blended diesel of producing this diesel oil.
Diesel engine is when work, and diesel oil is sprayed into cylinder through high-pressure pump, oil nozzle again through thick, fine cleaner.When diesel fuel temperature was reduced to the cold filter clogging temperature temperature, formed wax crystalline substance will block purifier and influence the normal fuel injection of oil circuit, and then influenced the works better of engine.
