specific Embodiment
[0012] Its specific example is as follows: take 100 grams of Buton rock asphalt ore, the proportion of asphalt in the Buton rock asphalt ore is about 30%, and then, the Buton rock asphalt ore is pulverized by a pulverizer until it is 40 mesh particles, that is It can be used as the raw material for the following rock bitumen purification. During purification, the above-mentioned rock powder and 100 grams of 30% soda ash are put into a 2L large reaction tank, and the temperature in the reaction tank reaches 110°C through electric heating; The device is constantly stirred to make the rock powder in the reaction tank fully react with soda ash to produce methane gas. After 2 hours of reaction, the bitumen in the rock powder is produced (or replaced). After the above reaction is separated by emulsification, 41 grams of reaction thing. Then, these reactants are put into another reaction tank again, through the above process, heated to 120°C, and at the same time, stirred by 0.8 kw ...

The invention discloses a technological method for purifying rock asphalts, belonging to the technical fields of purification techniques of rock asphalts and technological methods for purifying two kinds of rock asphalts. According to technical background, rock asphalts belong to one of natural asphalts, and because the rock asphalts are tightly combined with rocks, the purification of the rock asphalts is relatively inconvenient, and the rock asphalts are mainly used as a matrix asphalt modifier. The invention is designed for solving the technical problem that existing similar rock asphalt purification techniques are poor in environmental friendliness and energy saving effect, and the purification effect and process of rock asphalts are required to be further improved. According to the contents of the invention, the invention provides a technological method for purifying rock asphalts, wherein equipment for implementing the technological process for purifying rock asphalts comprises a crusher, a reaction tank, a stirrer, a methane recovery facility and a slag innocuous disposal facility. The technical scheme for solving the technical problem of the invention is as follows: the purification method is implemented by taking rock asphalts as a raw material, the ratio of rock powder to sodium carbonate in the reaction tank is 1:2, and through multiple deepening, stirring, dissolving and emulsification separation, a high-viscosity asphalt with a purity of 98% can be prepared. The technological method disclosed by the invention has the beneficial effects that the method is simple and feasible, good in purification effect, high in purity, energy-saving and environmental-friendly in reaction process, and good in recycling effect.
Description
technical field [0001] The invention relates to the purification technology of rock asphalt, which is a process method for the purification of rock asphalt. Background technique [0002] Rock asphalt is a kind of natural asphalt, which is the natural asphalt formed by the long-term evaporation and solidification of petroleum continuously emerging from the earth's crust and existing in mountains and rock fissures. That is, rock asphalt is an asphalt-like substance produced by oil after hundreds of millions of years of deposition and change under the combined effects of heat, pressure, oxidation, catalysts, bacteria, etc. According to its origin, Buton rock asphalt, Qingchuan rock asphalt, etc. . This kind of rock asphalt is inconvenient to purify because it is closely combined with the rock, and it is mainly used as a matrix asphalt modifier. However, the existing patents and prior art also involve some rock asphalt purification processes or equipment, such as the applicati...
