    摘要： The present invention relates to a method of improving a heavy hydrocarbon, such as bitumen, to a lighter more fluid product and, more specifically, to a final hydrocarbon product that is refinery-ready and meets pipeline transport criteria without the addition of diluent. A solid asphaltene by-product is created for easy handling and further processing. The invention is targeted to enhance Canadian bitumen, but has general application in improving any heavy hydrocarbon. The process comprises: (a) pre-heating a process fluid in a heater to a designed temperature; (b) moving the pre-heated process fluid to a reactor, and optimally converting asphaltenes in the process fluid within the reactor to produce a stream of thermally affected asphaltene-nch fraction( s), and a stream of non-condensible vapour and lighter liquid hydrocarbon(s); (c) deasphalting the thermally affected asphaltene-nch stream with a solvent extraction process into a stream of heavy deasphalted oil (DAO) and a second stream containing concentrated asphaltene; (d) separating dry thermally affected asphaltene solids from the second stream in a separation unit, recovering the process solvent; (e) a produced refinery feedstock comprising at least one of the produced streams.

    摘要： The present invention discloses a hot recycling heating method for old asphalt mixture, comprising: mixing old asphalt mixture with hot asphalt, with the temperature of the hot asphalt being higher than the temperature of the old asphalt mixture, but not higher than the standard temperature of heating asphalt; and heating the old asphalt mixture by heat exchange between the hot asphalt and the old asphalt mixture. The method is essentially featured by mixing the old asphalt mixture with the hot asphalt to result in gapless contact between the old asphalt mixture and the hot asphalt, thus the purpose of heating the old asphalt mixture by a gapless heat exchange environment between the hot asphalt and the old asphalt is reached; in addition, the method revolutionizes the traditional recycling heating modes for old asphalt, significantly reduces the degree of degradation in the performance of the old asphalt mixture during a heating process, improves the pavement performance of the old asphalt mixture, greatly reduces generation and emission of asphalt fume during a heating process, and avoids or reduces pollution and damage to natural environment.
