The invention discloses a new technique of biological diesel through urban sludge in the energy domain, which comprises the following steps: allocating the component formula with 70.5-56.5% sludge, 20.0-40.0% solvent, 0.5-2.5% adjuvant and 1.0% catalyst; adopting urban sludge or living effluent mud as sludge; selecting the solvent form rape oil, soyabean oil, waste kitchen oil and arachis oil; setting carbinol as adjuvant and aluminium chloride as catalyst; stirring these materials completely for 10-15min; reacting under 400-600 Deg C at 5.5-9.0Mpa for 30-60min; heating to 360 Deg C to obtain the distillate oil (gas oil); transmitting to blending procedure; adding 0.2-1.0% amyl nitrate to generate the diesel.

The invention discloses clean dimethoxymethane diesel oil, which is characterized in that the diesel oil is prepared by the following raw materials: dimethoxymethane, diesel oil and dimethoxymethane solution I, wherein the dimethoxymethane solution I is prepared by dissolving benzotriazole, dilinoleic acid, 2,6-tert-butyl-4-methylphenol, LD-r01 diesel lubricity improver, isooctyl nitrate(amyl nitrate) in the dimethoxymethane. A preparation method of the clean dimethoxymethane diesel oil comprises the following steps: A, mixing the dimethoxymethane, the diesel oil and the dimethoxymethane diesel oil solution I according to a ratio of 14.00:85.00:1.00, preparing D15 dimethoxymethane diesel oil; B, mixing the dimethoxymethane, the diesel oil and the dimethoxymethane diesel oil solution I according to the ratio of 29.00:70.00:1.00, and preparing the D30 dimethoxymethane diesel oil. Compared with the methanol diesel oil, the unique dimethoxymethane diesel oil in the invention has the advantages that the fire point of dimethoxymethane is low, cetane number is high and the like, and the dimethoxymethane diesel oil can be miscible with diesel oil in any proportion and has low cost and strong competitiveness.

The invention discloses a micro-emulsion diesel oil for diesel engine, which is prepared from the following raw materials according to the ratio of mass and volume percentage: 65-85% of diesel oil, 5-35% of H2O, 1-20% of oleic acid, and NaOH (weight ratio) 0.001 ~0.3%, amyl nitrate 0.1%~1%, Na2CO3 (weight ratio) 0.001~0.05%, NaCl 0.1%~1%, n-butanol 1~6%, ethanolamine 0.2~2%, kerosene 1~10%, The sum of the above raw materials is about 100%. Compared with pure diesel, the present invention can save 10-25% of non-renewable and increasingly depleted fossil fuel diesel under the condition of no significant change in power; Apply renewable energy to diesel engines to replace non-renewable and The increasingly depleted petrochemical energy diesel; can reduce the harmful components of diesel engine exhaust CO2, SO2, CO, black smoke, HC, etc.

The invention discloses a low-temperature resistance ethanol diesel oil which is prepared by materials of 75 to 90 percent of ethanol, 0.1 to 1 percent of naphthenic acid or sodium naphthenate or cobalt naphthenate or manganese naphthenate, 2 to 10 percent of isobutyl alcohol or butanol, 0.1 to 2 percent of acetone or cyclohexane, 0.3 to 0.5 percent of cetane number improver or amyl nitrate as well as 5 to 20 percent of triethylaluminium according to a volume percentage. Laboratory hot value detection and running experiment are carried out on the low-temperature resistance ethanol diesel oil prepared by the method and a testing unit is consigned for carrying out a physicochemical analysis experiment and an engine frame experiment. The running experiment result shows that the speed and the rotation speed of the engine when using the low-temperature resistance ethanol diesel oil do not have remarkable differences with that of using the diesel oil of a contrast experiment; the physicochemical analysis experiment shows that each index of the low-temperature resistance ethanol diesel oil is better or approaches to that of commercial diesel oil; the solidifying point is less than 48 DEG C below zero; and the frame experiment result shows that the smoke degree of the demarcated rotation speed of an exhaust emission diesel engine is reduced by 22 percent; and the CO is reduced by 34.6 percent. The low-temperature resistance ethanol diesel oil is used for a diesel oil engine and can remarkably reduce the exhaust contaminations of CO2 and CO.

The invention relates to concentration emulsified diesel fuel, in particular to concentration emulsified diesel fuel long in shelf life and low in cost and a preparation method thereof. The concentration emulsified diesel fuel is prepared through the following raw materials, parts by weight, 20-40 parts of diesel fuel, 16-22 parts of oleic acid, 5-12 parts of methanol, 2-6 parts of sodium nitrate, 26-36 parts of water, 5-14 parts of ethanolamine, 0.3-0.8 part of isooctyl nitrate or amyl nitrate and 0.3-0.8 part of ethylene glycol. Color and transparency of the concentration emulsified diesel fuel are the same as the diesel fuel, shelf life is long, emulation of the emulsified diesel fuel placed for more than 7 years can not be broken, stability is good, and a phenomenon of stratification of oil and water does not occur after the concentration emulsified diesel fuel is placed for 7 years. Through testing data verification, sulphur content is low, water content is high, production cost is greatly reduced, preparation process is simple, and corrosion level is low. The concentration emulsified diesel fuel is low in sulphur content and kinematic viscosity and can enable the diesel fuel to be burned completely when used as a diesel fuel additive, therefore emission quantity of harmful gas is reduced.

The invention provides a preparation method for methanol gasoline with good stability, and belongs to the technical field of synthetic fuels. The preparation method comprises the following steps: steps one, putting heavy benzol, alkyl naphthalene, amyl nitrate, sodium biphosphate, ethylene-vinyl acetate copolymer, light diesel oil, tebutate peroxide, 70# gasoline, a dispersing agent, and a metal deactivator into a reactor and stirring to obtain a mixture; adding methanol into the mixture, cooling down, stirring continuously, and standing to obtain the methanol gasoline. The methanol gasoline provide by the invention has good burning performance, and is not changed in performance and has no sediments after being placed for a long time.
