Background technology
In recent years, petroleum heavy in poor quality problem is all suffered from China or even world wide, but with the hair of economy
Exhibition, light-end products requirement but increasingly increase, and this requires us that mink cell focus is more processed into light-end products, to meet to pass through
Needs of the Ji development to the high-quality oil product of lightweight.At present, the main technological means of upgrading have it is conventional thermal cracking, face hydrogen and subtract
Glue cracking, hydrogen supply visbreaking and face hydrogen hydrogen supply visbreaking.Modification oil stability that wherein conventional visbreaking obtains, 0API
Etc. poor, and other modification technologies are subjected to the limit that hydrogen source, Hydrogen activation and hydrogen supply agent develop the problems such as preferred difficulty is big
System.
Polycyclic aromatic hydrocarbon is rich in viscous crude, some of which can be hydrogenated with the conditions of relatively relaxing, and some are under the conditions of relatively relaxing
But it is difficult to be hydrogenated with.CO hydro-thermals become the newborn hydrogen caused by transducing with high activity, if newborn hydrogen original position can be acted on into viscous crude
In under the conditions of relatively relaxing the polycyclic aromatic hydrocarbon that can be hydrogenated with, obtained hydrogenation products on the one hand can carry out hydrogen turn inside viscous crude
Move, internal potential hydrogen supply agent effect is played, so as to play a part of hydrogenation to the viscous crude molecule for being difficult to be hydrogenated with the conditions of mitigation;
On the other hand, its own is changed into the polycyclic aromatic hydrocarbon being easily hydrogenated with again, so as to realize effect that newborn hydrogen efficiently transmits into viscous crude.
Raw material CO in CO hydro-thermal conversion processes can be obtained by petroleum coke vaporization caused by delayed coking, can not only not had to H2
Further activation and it is significantly cost-effective, can also more efficiently lift upgrading effect.Therefore, polycyclic aromatic hydrocarbon hydrogen migration
It is a problem with huge practical value to upgrading with the conversion of CO hydro-thermals.
The content of the invention
The purpose of the present invention is aiming at drawbacks described above existing for prior art, there is provided a kind of analogue experiment installation, this hair
It is bright to replace the polycyclic aromatic hydrocarbon in viscous crude in the case where CO hydro-thermals convert environment in experimental simulation device using polycyclic aromatic hydrocarbon model compound
Middle carry out hydrogenation reaction, and then polycyclic aromatic hydrocarbon is changed into the compound with virtue and cycloalkanes ring structure, so as to change as viscous crude
Potential hydrogen supply agent during matter, reduce and generate oily viscosity, improve and generate oily stability, be finally reached the mesh that viscous crude efficiently modifies
