Description
Technical field
The present invention relates to waste oil comprehensive utilization and fuel oil processing technique field, particularly a kind of liquid-phase catalyst and preparation method of splitting method waste oil regeneration diesel oil that urge.
Background technology
Waste and old oils mainly comprises mineral oil (petroleum-type) and vegetable and animals oils (grease class), and they are very different on composition.The comprehensive utilization of present waste and old oils mainly can be divided into three types, and one type is that waste and old oil product (mineral oils) is carried out being used as low side fuel after the roughing, causes resource utilization to can not get performance, causes the wasting of resources.Another kind of is the oil refining process of continuing to use the big factory of petrochemical industry; Waste oil removal of impurities → the go into still → intensification → waste oil steam that dewaters gets into the thick diamicton of Catalytic Layer → remove → remove thin diamicton → absorption → condensation → acid treatment → alkali diesel oil that neutralizes → be deployed into, complex process, and equipment is many; Investment is big, and general producer is difficult to bear.Also have one type to be that waste cooking oil or acidifying oil (grease class) are produced biodiesel processes, the someone claims that without soda acid with methyl alcohol and simple distillation has just become qualified biodiesel product once, this is to disguise replacement of concept.This method is basic not to change the carbon-chain structure of molecule just not with the molecular weight reduction of grease yet, and refining depth and anti-oxidant degree do not reach requirement, and such oil still is original grease still, can't reach the physical and chemical index of diesel oil.The state-of-the-art technology of the comprehensive utilization of present waste and old oils it is said it is molecular clock or high vacuum distillation; Both solved color problem, and removed soda acid again and washed problem such as cause pH-value to exceed standard, resistance to emulsion is defective, but investment had been big; Specification requirement is high, and practicality is not strong.We can say also there is not a cover diesel regenerated continuous type of production industrialized unit of waste oil cracking truly in the market, therefore the diesel oil viscosity of regeneration, density, colourity, flash-point, non-oxidizability etc. are not up to standard.
Traditional process for treating waste oil is waste oil to be added distillation still directly distill, and the oil content that distills out is made with extra care with bronsted lowry acids and bases bronsted lowry.The oil viscosity that the method is made is big, and density is big, will the oxidation blackening in very short time, and stink and the peculiar smell of oil the inside be difficult to remove, and the processing of acid sludge and waste water and discharge and can cause serious secondary pollution to environment.
Domestic regeneration about waste and old oil product had many reports, and waste and old oil product is diesel regenerated, fuel oil also has some reports or unofficially report or advertisement, but really gets into practical application or large-scale production seldom.Because oil product regeneration or waste and old oil product is diesel regenerated, the control of fuel oil difficult quality, or quality dissatisfaction or environmental protection have problem, and perhaps the performance of product itself is not good, is difficult to compete with regular oil product.
The waste oil regeneration liquid-phase catalyst almost is blank on the domestic market at present, and traditional method adds distillation still with waste oil exactly, under the situation that does not add any catalyst, directly distills; The front was said; The oil viscosity of making like this is big, and density is big, will the oxidation blackening in very short time.Even the somebody adds some conventional chemical industry medicaments when distillation; Do not have the effect of catalyst yet, the big molecule in can not catalytic pyrolysis waste oil, the oil product of making like this turns blue, greening, rubescent; Contain a large amount of machine oil compositions, can not meet the fuel oil requirement at all.
