Abstract
The invention discloses a low-viscosity white oil which comprises the following alkanes components in percentage by weight: 5-15% of C13 and C16, 70-90% of C14 and 5-15% of C15. The mass content of normal paraffin hydrocarbons in the alkane components is greater than or equal to 80%. After the low-viscosity white oil is intensely oscillated and stopped, the foam can disappear within two seconds, and no carbon deposit is generated after the white oil is continuously combusted for 48 hours.
Description
Technical field
The present invention relates to a kind of low viscosity white oil, particularly relate to a kind of low viscosity non-foam, without carbon deposit white oil.
Background technology
At present, the low viscosity white oil existence of state, inside and outside production is very easily bubbled, and produces the drawbacks such as carbon deposit during burning.White oil quality Standard General can not propose independent requirement to foam, carbon deposit two indexs, but along with the fast development of some special industry, currently available products can not be satisfied the demand, has higher requirement to this white oil quality.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of can meet industry requirement still, without the low viscosity white oil of carbon deposit.
A kind of low viscosity white oil of the present invention, it comprises following alkane component, and normal paraffin mass content>=80% in described alkane component, described alkane component is counted with weight percent: C
13and C
165-15%, C
1470-90%, C
155-15%.
The invention has the beneficial effects as follows:
1. mainly character is uneven or viscosity is excessive causes for low viscosity white oil foaming reason, isometry component in low viscosity white oil too much can cause character greatly uneven, thus cause foaming, when ensureing that spatial isomerism is consistent, isomerization should be reduced as far as possible, the present invention adopts 5A molecular sieve to carry out the positive isomery of molecule to low viscosity white oil and splits, and make positive structure rate >=80% of white oil of the present invention, white oil of the present invention is not easy to foaming.
2. carbon distribution is wide, not only can bring the change of flash-point and pour point, and composition and property more can be caused uneven, so the present invention passes through rectifying constriction carbon number distribution, makes carbon number distribution at C
13-C
16, peak value is at C
14, so white oil oxidation stability of the present invention significantly improves.
3. the present invention has carried out hydrogenation to low viscosity white oil, has eliminated double bond compound, greatly reduces the carbon deposit because burning can produce.
4. low viscosity white oil involved in the present invention, after concuss stops, foam disappears less than in two seconds, and continuous burning 48 hours is also without carbon deposit.
Accompanying drawing explanation
Accompanying drawing is the schematic flow sheet of the preparation process of a kind of low viscosity white oil of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
A kind of low viscosity white oil of the present invention, it comprises following alkane component, and normal paraffin mass content>=80% in described alkane component, described alkane component is counted with weight percent: C
