Embodiment １

[0012] Methanol gasoline prepared by using coal-based light oil, according to the preparation of 100 parts of methanol gasoline as an example, first put the coal-based light oil on the distillation equipment to take fractions (distilled component oils) at ≤ 120 ° C, and then each component is divided by weight. The numbers are 26 parts of methanol, 1.2 parts of co-solvent, 17.1 parts of national standard 90# gasoline, 40 parts of distilled oil, 14.5 parts of aromatics, and 1.2 parts of additives. Qualified finished methanol gasoline can be obtained by the process recorded in the patent literature of the fully automatic integrated online blending method of diesel oil. Each part of co-solvent is prepared from isobutanol, isopropanol and n-pentanol in a weight ratio of 3:1:2; each part of additive is prepared from tetrahydrofuran, MTBE and toluene in a weight ratio of 1:1:1 .

Embodiment ２

[0014] Methanol gasoline prepared by using coal-based light oil, according to the preparation of 100 parts of methanol gasoline as an example, first put the coal-based light oil on the distillation equipment to take fractions (distilled component oils) at ≤ 120 ° C, and then each component is divided by weight. The numbers are 30 parts of methanol, 1 part of co-solvent, 17 parts of national standard 90# gasoline, 36 parts of distilled oil, 14.3 parts of aromatics, and 1.7 parts of additives. The utilization publication number is CN 103706286 A, and the name of the invention is Qualified finished methanol gasoline can be obtained by the process recorded in the patent document of a fully automatic integrated online blending method of methanol gasoline and diesel. Each part of co-solvent is prepared from isobutanol, isopropanol and n-pentanol in a weight ratio of 3:1:2; each part of additive is prepared from tetrahydrofuran, MTBE and toluene in a weight ratio of 1:1:1 .

Embodiment ３

[0016] Methanol gasoline prepared by using coal-based light oil, according to the preparation of 100 parts of methanol gasoline as an example, first put the coal-based light oil on the distillation equipment to take fractions (distilled component oils) at ≤ 120 ° C, and then each component is separated by weight. The numbers are 24.3 parts of methanol, 1.6 parts of co-solvent, 17.4 parts of national standard 90# gasoline, 40 parts of distilled component oil, 14 parts of aromatics, and 2.7 parts of additives. The utilization publication number is CN 103706286 A, Qualified finished methanol gasoline can be obtained by the process recorded in the patent document named as a fully automatic integrated online blending method of methanol gasoline and diesel. Each part of co-solvent is prepared from isobutanol, isopropanol and n-pentanol in a weight ratio of 3:1:2; each part of additive is prepared from tetrahydrofuran, MTBE and toluene in a weight ratio of 1:1:1 .

Abstract

The invention relates to a methanol gasoline prepared by means of coal-based light oil. The methanol gasoline comprises, by weight, 35.7-40.2% of distillation component oil, 11.96-30.4% of methyl alcohol, 1.04-1.6% of complex solubilizer, 17-17.4% of national standard 90# gasoline, 14.28-14.62% of aromatic hydrocarbon and 1.02-2.78% of additives. Raw materials of the methanol gasoline are rich and easy to obtain, high economic advantages are obtained, and the methanol gasoline has the advantages of being environmentally friendly, saving energy and being high in power performance.

Description

technical field [0001] The invention belongs to fuel for vehicles, in particular to methanol gasoline prepared from coal-based light oil. Background technique [0002] New energy resources have great potential and low environmental pollution, which is an important energy that is conducive to the harmonious development of man and nature. Faced with the increasing imbalance between supply and demand of traditional energy, countries all over the world have increased their efforts in the development and utilization of new energy and energy new technologies. my country is rich in coal resources, but oil resources are relatively scarce, so the use of coal-based naphtha, methanol and other coal chemical raw materials to prepare vehicle fuels is one of the future development directions of alternative energy. [0003] According to the statistics of relevant international organizations, in September 2013, my country imported 6.3 million barrels of crude oil per day, and its oil d...
