Abstract

The invention provides a method for preparing diesel oil for alpine regions with gas condensate and coal tar. The method comprises the following steps of: transferring the gas condensate under normal temperature to heating equipment to be heated, wherein the heating temperature is 60-180 DEG C; transferring the heated gas condensate to evaporation separation equipment to undergo evaporation separation to obtain light components and heavy components of the gas condensate; and blending the heavy components of the gas condensate, light oil fractions of the coal tar and a special additive and standing to obtain the diesel oil, wherein the specific steps are as follows: pumping the heavy components of the gas condensate, the light oil fractions of the coal tar and the special additive into a reaction kettle with a stirring device according to the predetermined weight percent, stirring the materials for 30-60min, discharging the product and storing the product in a storage tank statically for 24h to obtain the diesel oil; and the weight percents of the heavy components of the gas condensate, the light oil fractions of the coal tar and the special additive are respectively 20-70%, 20-60% and 10-20%.

Description

Technical field: [0001] The invention relates to the technical field of diesel production, in particular to a method for preparing diesel used in alpine regions from condensate oil and coal tar. Background technique: [0002] Under the conditions of shortage of oil resources in the world, rising crude oil prices, and increasing environmental pressure, various alternative resources have formed a new round of rapid development. The per capita possession of oil resources in my country is less than 1 / 16 of the world average. Constrained by resources, the contradiction between supply and demand of crude oil in my country is becoming more and more prominent, and the dependence on foreign oil is getting higher and higher. The development of new energy is particularly important and urgent. Especially in recent years, with the rapid development of my country's national economy, the number of various diesel vehicles and construction machinery is increasing rapidly, increasing the dem...
