Abstract
A process for preparing gasoline, kerosene, diesel oil and high-grade asphalt from natural asphalt ore includes such steps as depolymerizing at 200-400 deg.C, fragmentizing with the fragmenting agent prepared from sulfuric acid and hydrochloric acid in weight ratio of (4-5):1, and extracting with extractant which is the washing oil of cokery.
Description
The place of storing the rock asphalt ore in the world is for counting seldom.Only find at present the Qingchuan County in area, Russian Wu Er river bend and China Sichuan.Therefore the development technique to the rock asphalt ore almost is a blank.The rock asphalt ore contains valuable useful composition, and its crude content is about 20%, and asphalt content has considerable exploitation and is worth about 55%.Rock asphalt ore medium pitch content height belongs to polymerization substantially again, so the research of technique difficulty is quite big, and the crude oil composition complexity of in addition producing again, colloid is very high, and it can not adopt the petroleum crude oil smelting process at all.Up to now, also do not utilize the rock asphalt ore to come the suitability for industrialized production energy and senior bituminous method and technology at home and abroad.For development and utilization rock asphalt ore effectively, people press for a kind of sophisticated novel method and new technology.
The objective of the invention is in order to solve effective development and utilization of rock asphalt ore.Provide a kind of rock asphalt ore that utilizes to come suitability for industrialized production gasoline, kerosene, diesel oil and senior bituminous method as raw material.
The objective of the invention is to reach by following technical measures: the rock asphalt ore is broken earlier, and pulverize the back.Rock asphalt breeze after will pulverizing again carries out depolymerization.Crude oil that obtains after the depolymerization and inflammable gas make crude oil separate with inflammable gas after compound cooling.Isolated crude oil is handled through adsorption bleaching after fracture is handled again, and the crude oil that will decolour and handle is again handled through heat refining and smart gold-plating traditional technology afterwards, just can obtain gasoline, kerosene and diesel oil respectively.And the pitch that the rock asphalt ore powder obtains after depolymerization is earlier got processing through quenching, and quenches and handles through dedust after getting again, and the heavy oil that adds fusing point afterwards again and be 25 ℃ dissolves again, just can obtain high-grade road bitumen and building asphalt.In whole technological process, required depolymerization temperature should be controlled between 200 ℃-400 ℃ during its depolymerization; Used clastogen was to be that 1.82 sulfuric acid and proportion are 1.1 hydrochloric acid with proportion when its fracture was handled, by weight 4-5: 1 is formulated.And the adding of this clastogen heavily adds by the 4%-6% of former weight of oil; It is quenched, and used extractant is a washing oil of selecting the coal coking plant for use when getting pitch, needs during use it is added to 220 ℃-260 ℃.
Accompanying drawing is a process flow sheet of the present invention.
The present invention is described in further detail below in conjunction with embodiment: at first after the rock asphalt ore reduction, be ground into fine powder again.Then the rock asphalt breeze is sent in the depolymerization still, under 320 ℃ temperature, sealed depolymerization.Can obtain the mixture of combustion gas and crude oil after the depolymerization, and through the pitch of depolymerization.Wherein gas, the compound cooling tower of oil mixt suction are cooled off.Send in the mixing kettle again after the cooling and separate, so inflammable gas and crude oil here are separated.Part in the inflammable gas of separating can be returned the workshop and use, and the overwhelming majority is sold as the packing of product combustion gas finished product by solvent absorbing; The crude oil of separating is admitted in the fracture still, is that 1.82 sulfuric acid and proportion are 1.1 hydrochloric acid with proportion, by weight the fracture of blowing of the clastogen of preparation in 5: 1, add of 5% adding of the weight of clastogen by former weight of oil.Blow and to leave standstill one hour after fracture is finished, earlier fracture material (mainly being colloid and pitch) is emitted.And then post-rift crude oil sent into carry out adsorption bleaching in the white clay jar that atlapulgite is housed and handle.Crude oil after adsorption bleaching is handled need leave standstill again one hour, after the white clay that sinks to the bottom is removed, just crude oil can be sent into and carry out heat refining in the heat refining still, and the crude oil behind the heat refining is earlier by rectifying tower A intercepting gasoline, again by rectifying tower B intercepting kerosene and diesel oil.Remaining is heavy oil, it is entered do the asphalt flux use in the heavy oil storage tank.
The pitch that obtains after the depolymerization was quenched with the first oil that is heated to 240 ℃ coal coking plant before this and was got processing.Quench and get the back and adopt the method for press filtration to carry out ash to handle, leach leave standstill three hours behind the ash after, send into the solvent recuperation still and regain solvent, and to add fusing point be that 25 ℃ heavy oil dissolves again, be asphaltic products. after the dissolving.According to the bituminous specification, add the pitch that different quantity of solvent just can be produced the high-grade various trades mark.
The present invention not only is effective development and utilization of rock asphalt ore, provide a kind of can suitability for industrialized production, produce gasoline, kerosene, diesel oil and senior bituminous method reliably, sophisticated with the rock asphalt ore, and this production method conversion value is high, environment is not polluted the real initiative that belongs to again.
