Formulation process for synthesis of gasoline with methanol

Abstract

The invention discloses a preparation process for methanol synthetic gasoline which is mixed by the following raw materials, in weight percentage: 40 percent to 95 percent of industrial methanol; national standard gasoline or basic gasoline or a mixture thereof in random proportion, or 0 percent to 70 percent of mixture of two or more basic gasoline in random proportion; 2 percent to 5 percent of fluxing denaturant; and 0.1 percent to 0.5 percent of composite functional agent. The preparation process adopts the steps: firstly the fluxing denaturant is added into the industrial methanol for stirring for 5 minutes to 10 minutes under the conditions of normal temperature, atmospheric pressure, no spark, fire prevention and explosion protection, the composite functional agent is then added thereto for the agitation for 5 minutes to 10 minutes, then the national standard gasoline or the basic gasoline or the mixture thereof in random proportion is added thereto for being continuously stirred for 5 minutes, finally completing the preparation. The methanol synthetic gasoline prepared by the process is to add inexpensive combustible liquid methanol and other liquid combustible substances with relatively large reserves in great proportions into the traditional gasoline, the substitution rate of the petroleum composition is extremely high, the energy can be saved, the national petroleum import pressure can be reduced, massive foreign exchange disbursement can be saved, and the socioeconomic performance is good, meanwhile, the process has technical advantages of environmental protection, good power performance, corrosion resistance, extensive use scope, stable quality and simple and convenient production, and being worth wide promotion.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a process for preparing methanol-synthesized gasoline. technical background [0002] The development of environmentally friendly new energy as an alternative fuel is the need of the national energy strategy and environmental strategy, as well as the need of the sustainable development of my country's industry and even the entire society. Methanol gasoline is such a new energy source, which has certain applications in daily life, but the existing methanol gasoline is simply mixed with a certain proportion of methanol in gasoline, which is in the case of a low proportion of 3-5%. However, with the increase of the proportion of methanol, many problems such as low heating value of methanol, lack of power, high fuel consumption, difficult cold start, high temperature air resistance, poor stability, corrosion and swelling, and miscibility with gasoline will occur. One by one expose...
