Abstract
The invention discloses a diesel oil decolorizing agent and a preparation method thereof. The diesel oil decolorizing agent comprises the following components in percentage by weight: 40-60% of sulfuric acid (with concentration of larger than or equal to 98%), 30-40% of absolute ethyl alcohol and 10-20% of furfural. The preparation method comprises the steps of mixing sulfuric acid (with concentration of larger than or equal to 98%), absolute ethyl alcohol, furfural and CuO or ZnO, and stirring for 5-15 minutes. Compared with the prior art, the diesel oil decolorizing agent has the beneficial effects that the loss of an oil product is low, and the chroma of the oil product reaches to the national standard; the diesel oil decolorizing agent is long in stable period, free of reduction, clear, transparent and wide in application range; in addition, the diesel oil decolorizing agent is low in cost and small in dosage; the preparation method is convenient and rapid in operation; and waste residues washed by using the diesel oil decolorizing agent cannot be caked, bonded or solidified and can be recycled, so that the problem of environment pollution is solved.
Description
Technical field
The present invention relates to a kind of diesel decoloring agent, specifically, relate to a kind of diesel decoloring agent and preparation method thereof.
Background technology
The chocolate complex mixture that pitch is made up of hydrocarbon polymer and the nonmetal derivative thereof of different molecular weight, is in a liquid state, and is a kind of waterproof and dampproof and rot-resistant organic gel gel material.For industry and surfacings etc. such as coating, plastics, rubber.
Produce petroleum pitch full-bodied oil is refined by atmospheric and vacuum distillation unit, its byproduct normal pressure oil subtract one, two, third fractional oil has low condensation point, high flash point and full-bodied characteristic, is the good raw material that does diesel oil, lubricating oil.
But because it is high containing a large amount of resin and asphalt and acid number, viscosity index is low, therefore can not directly utilize.Meanwhile, also can supervene the insoluble gluey settling of a large amount of black in oil product, cause the obstruction of oil supply line, affect normal fuel injection, this fuel combustion thing forms carbon distribution on engine nozzle, and aggravation engine scuffing also causes spray nozzle clogging.
Summary of the invention
The present invention has overcome shortcoming of the prior art, and a kind of diesel decoloring agent and preparation method thereof is provided, and its good decolorizing effect can operate at normal temperatures and pressures, and decoloration process is simple, easy to use, and consumption is little, applied widely.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of diesel decoloring agent, each component and weight percent content are as follows:
Sulfuric acid (>=98%): 40～60%,
Dehydrated alcohol: 30～40%,
Furfural: 10～20%.
Further, also comprise CuO or ZnO, the 2-5% that its addition is said components.
Further, each component and weight percent content are as follows:
Sulfuric acid (>=98%): 50%,
Dehydrated alcohol: 30%,
Furfural: 20%,
CuO is 3% of said components.
Further, each component and weight percent content are as follows:
Sulfuric acid (>=98%): 60%,
Dehydrated alcohol: 30%,
Furfural: 10%,
ZnO is 5% of said components.
A kind of preparation method of diesel decoloring agent:
By sulfuric acid (>=98%), dehydrated alcohol, furfural, CuO or ZnO mix and blend 5 to 15 minutes.
Compared with prior art, the invention has the beneficial effects as follows:
A kind of diesel decoloring agent of the present invention and preparation method thereof, oil loss is few, colourity reaches GB, grows stationary phase, does not reduce, as clear as crystal, applied widely, and cost is low, consumption is little, waste residue convenient to operation, to wash out with this agent, do not lump, non-caked, do not solidify, can utilization of waste material, solve environmental issue.
