24Heavy hydrocarbon prepare the brewing equipment and the technology thereof of light paraffins.
Background technology
Present oil shortage, energy shortage has become the major issue that influences Economic development, industry, agricultural, life, there is not one can leave the energy, but tellurian resource is not nexhaustible, and resources such as oil, coal have all been sent warning to people, at present, human recover petroleum resource has reached the limit.7,000 ten thousand tons of China's petroleum resource gaps in 2003, agricultural traffic material fuel oil, the consumption of ocean exploitation boats and ships heavy gas oil go up day by day.Investigate in by the end of October, 2003 according to: 2300 yuan/ton of fuel oil market valencys, 3100 yuan/ton of solar oil prices, existing market diesel oil retail price has broken through 4100 yuan/ton.Be the Energy resources approach exhaustions on one side, the other side is that Energy resources can not be regenerated, and seeks the new energy, produces cheap fuel, becomes urgent task of world energy sources science.For traffic in the world in future, industrial energy fuel, radical solving method is to seek the fuel that can substitute oil.Some countries of Europe, the U.S., Japan all give great attention to biofuel, and the respective standard of biofuel has been formulated in Europe, and this biofuel derives from soybean, rapeseed oil.Calendar year 2001, the yield of biodiesel of European Union broke through 1,000,000 tons, wherein France and Germany are maximum factory states, biofuel can be used on existing diesel engine, need not repacking, benz, BMW, the Volkswagen of Germany, various types of diesel engine of production all allow to use biofuel, and the U.S. begins the production biofuel in early 1990s, in addition, Canada, Brazil, Japan, new southwest and some other country are also in development biodiesel technology and industry.But because this biofuel is that soybean, vegetable seed are raw material, its cost is very high, brings certain difficulty for the popularization of biofuel.
The physicist thinks: plant that carbohydrate dry powder and photosynthesis are grown up down and crop, withered grass, academicly be called biomass resource, if be processed into particle, with oil, the mixed fermentation of hydro carbons microorganism, they are sublimate into to a certain degree, as long as alkylation a little, add strong oxidizer, just can synthesize primary explosive.Blast is the embodiment that material releases energy.At present, carbohydrate such as plant leaf, stalk, withered grass, except that a small part was used as agricultural byproducts or handicraft materials consumption, the overwhelming majority abandoned the field and burns in vain.Through measuring: routine is lighted or the mode of nature consumes stalk, only utilized the 12-13% of their energy, China abounds with 4600 kinds of gramineae plants, and wherein crop materials such as farm crop paddy rice, wheat, corn, jowar are produced 3.7 hundred million tons per year, 1.2 hundred million tons of wild withered grass, production and utilization that can be year after year, nexhaustible, inexhaustible, at present, countries in the world all are not used as industrial important source material to it, abandon or burn, had a strong impact on natural ecological environment.
Our oil Refining Technologies also can't be eaten the crude oil of exploiting out fully to do and be pressed only at present, the part oil field, industrial waste remains quite a few deposition heavy hydrocarbon resource, as, 1,700 ten thousand tons of the high viscous crudes that refining of petroleum can't achieve the goal, high 9,000,000 tons of the oil that coagulate, refine 3,000 ten thousand tons in residual oil etc., also have some depleted doughnuts, depleted engineering macromolecular material, discarded pitch, the coal tar of coking etc. can be found everywhere, not only cause the waste of resource, and cause environmental pollution, if these materials are all used raw material as the energy and twice-laid stuff, problem of environmental pollution not only can be solved, and problems such as the energy and regeneration novel material can be solved.
Our oil refining process still is a high energy consumption at present, expensive, the production technique of high-risk, with regard to the atmospheric and vacuum distillation unit of lifting refinery is example, when crude oil is heated to 360 ℃ in process furnace, part crude oil is vaporized, gasoline wherein, kerosene, the component that boiling points such as diesel oil are lower is preferentially vaporized, become gas, and heavy oil, the higher component of boiling points such as residual oil still is a liquid, enter atmospheric fractional tower, gas-liquid two-phase is able to initial gross separation, contains gasoline, kerosene, the mixed gas of diesel oil, through multiple condensation, heat exchange, mass exchange, at the lower boiling gasoline that arrives of cat head, obtain kerosene at last at the middle part, diesel oil, the bottom obtains heavy oil, because of the heavy oil boiling point very high, vaporization need be heated to 500 ℃, and under this temperature, oil product can decompose, therefore to carry out vacuum fractionation to heavy oil, at the vacuum fractionation tower, part heavy oil is vaporized at 400 ℃, improves the yield of oil product with this.167 of the total sized devices of atmospheric and vacuum distillation unit, be divided into five big classes, separation column is with regard to five, and the highest reaches 35 meters, 40 layers of column plates, three in process furnace, the highest reaches 17 meters, interchanger, water cooler, pump, container etc., do not comprise pipeline, the equipment rolled steel dosage reaches 5400 tons, so many equipment and pipeline is heated to 360 ℃ of temperature and maintain between 360-400 ℃ throughout the year, and energy consumption is well imagined.
Summary of the invention
The objective of the invention is to utilize the little engineering transition intersection of biological peptide transfer factor technology, design a kind of brewing equipment, with each kind of plant, crop material, withered grass, after attrition process and the mixed fermentation of biological peptide heavy hydrocarbon resolvase, mix with the part heavy hydrocarbons, the middle two hydrogen transfer factor prozymes of biology that switch are brewageed lightweight alkyl hydrocarbon C
