Description

A kind of High-octane mogas and preparation method thereof

Technical field

It is the invention belongs to chemical field, in particular to a kind of to utilize isopentane reconciliation High-octane mogas and its preparation Method.

Background technique

Motor petrol is important traffic fuel, and yield accounts for about the 20% of crude runs, mainly there is the chain of C5~C11 Alkane, cycloalkane, alkene, aromatic hydrocarbons and a small amount of sulfur-bearing, nitrogen, oxygen heteroatom compound composition.

Aromatic hydrocarbons can aggravate the carbon distribution of automobile cylinder, increase tail gas discharge capacity, improve CO, HC, NO concentration in tail gas, break annular space Ozone in gas；Aromatic hydrocarbons incomplete combustion can also generate carcinogen.Alkene is a kind of unstable material, easily in engine oil inlet Colloid and precipitating are generated in system, nozzle and cylinder, are declined engine efficiency, are influenced its service life, while increasing in tail gas PM content.

It is influenced by naphtha surplus, naphtha preparation amount of plan is lower, results in naphtha component quilt well below production capacity It is forced into diesel component or calls in gasoline.If calling in gasoline, because naphtha octane number is low, need to consume the toluene of a large amount of high prices With BTX aromatics component, reconcile at high cost.In addition, there is sulfur content and the exceeded feelings of olefin(e) centent in gasoline harmonic process sometimes Condition, it is also necessary to be reconciled with part naphtha, which increases the consumption of high-octane rating blend component, increase and are produced into This.

Isopentane has RON (93.2) and MON (90.8) relatively high, and anti-knock index is high, can provide enough burnings Calorific value reduces the discharge of pernicious gas in tail gas, and the advantages of non-aromatics/olefin compound, therefore, isolates in naphtha Isopentane component is a kind of extraordinary gasoline accord method for the scheme of blended gasoline.

Summary of the invention

It is an object of the invention to produce and reach the one of relevant national standard using isopentane as gasoline blend component Kind High-octane mogas and preparation method.

To achieve the above object, following technical scheme of the present invention are as follows: a kind of High-octane mogas, including The component of following weight percentage:

5%~15% isopentane, 40%~45% S_ZORB treated gasoline, 8%~9% high pressure heavy naphtha, 4%~5% methyl tertiary butyl ether(MTBE), 2%~3% light raffinate of hexane, 10%~11% DA401B tower bottom liquid, 7%~8% Reforming raffinate oil and 14%~16% C9 aromatic hydrocarbons.

The purity of the isopentane is 99%.

Isopentane, S_ZORB are refined vapour under normal temperature and pressure conditions by a kind of preparation method of High-octane mogas Oil, high pressure heavy naphtha, methyl tertiary butyl ether(MTBE), the light raffinate of hexane, DA401B tower bottom liquid, reforming raffinate oil and C9 aromatic hydrocarbons are added to It is stirred, then is stood to get purpose product in Mixer pot.

The mixing time is more than or equal to 10min.

The time of repose is more than or equal to 4h.

S_ZORB treated gasoline, methyl tertiary butyl ether(MTBE), the light raffinate of hexane, DA401B tower bottom liquid, is reformed high pressure heavy naphtha It raffinates oil, C9 aromatic hydrocarbons is Yangtze petroleum chemicals.

The invention has the advantages that (1) simple process, condition are easily achieved, resource consumption is few；(2) naphtha mistake is solved It is surplus, it is difficult to utilize, it is difficult to which that the problem of selling isolates isopentane for blended gasoline, greatly increase its utility value； (3) it is detected, reconciles out No. 92 gasoline for meeting national standard；(4) product is as clear as crystal, high-quality, and stability is high；(5) it produces The good environmental protection of product can reduce the discharge of pernicious gas in tail gas.
