Description
Technical Field
The invention belongs to the technical field of producing petroleum products by using heavy oil processing byproducts, and particularly relates to a building asphalt product prepared by using hard deoiled asphalt, in particular to a building asphalt product prepared by blending paraffin-based raw material hard deoiled asphalt.
Background
The production process of petroleum asphalt comprises an atmospheric and vacuum distillation method (obtaining straight-run asphalt), an oxidation method, a solvent deasphalting method, a blending method, a modification method and effective combination of the above processes.
The solvent deasphalting process in petroleum processing aims at removing asphaltene and most colloid in vacuum residue, originally aims at obtaining high-viscosity lubricating oil raw material, is developed later, and is increasingly used for providing raw materials with low carbon residue value and heavy metal content for catalytic cracking or hydrocracking, and solvent deasphalting is used for producing deasphalted oil and also used for producing deoiled asphalt.
The deoiled asphalt mainly comprises asphaltene and colloid, and contains a certain amount of polycyclic aromatic hydrocarbon, and due to the characteristics of the solvent deasphalting process, the deoiled asphalt has high content of hard components (colloid and asphaltene) and low content of soft components (saturated component and aromatic component). The paraffin-based vacuum residue solvent deasphalting which aims at producing catalytic cracking materials generally has harsh operating conditions, low yield of the deasphalted asphalt, high softening point, low penetration degree and almost no ductility, and other components are required to be added for coordinating related properties when the deasphalted asphalt is used for producing building asphalt, so that the penetration degree and the ductility are properly improved on the premise of ensuring the softening point.
Most of the currently disclosed patents for building asphalt products focus on oxidation production technologies, for example, publication No. CN 1093394A discloses the oxidation production of No. 30 building asphalt from deoiled asphalt; there is also a technology for producing building asphalt by adopting a catalytic oxidation method; for example, the application number 97121664 adopts a catalyst such as phosphoric acid to carry out catalytic oxidation on the vacuum residue to produce the building asphalt; also adopts a chemical condensation method to produce the building asphalt, such as the technology of the publication No. CN106317917A which takes deoiled asphalt and furfural extract oil as reaction raw materials and takes one or more of polyphosphoric acid, phosphoric acid or sulfur as a condensing agent to produce the building asphalt; in addition, there are also patents for improving the building asphalt by polymer modification at home and abroad, for example, US 4868233 and CN 101864182A, CN 1111567C, CN 97121664.9 both adopt polymers to modify the building asphalt, so that the high-temperature and low-temperature performances of the building asphalt are improved, and the patent technology of polymer modification does not relate to the raw material production technology; domestic scholars, Jiasheng, and the like report that building asphalt is prepared by introducing superheated steam into vacuum residue as a raw material to perform cracking condensation; all published patent methods have complex processes, harsh conditions, are not environment-friendly and have relatively high cost.
