One of key of the invention and innovative point are directly to be produced coal using solvent and catalyst degradation and reconfiguration technique
Aromatic hydrocarbons.
It is of the invention crucial and innovative point second is that having broken the unrenewable final conclusion of oil.
Existing theory can be opened《Encyclopadia Sinica chemissues one》P306 pages is discussed in this way：If " producing high-molecular
The atom connection in object is closed when reticulating, then is net high-polymer, this macromolecule due to not generally being planar structure but
Stereochemical structure, so it is also three-dimensional polymeric molecule.Three-dimensional polymeric molecule cannot melt when heating, and can only become soft elasticity increase；No
It can dissolve, can only be swollen in certain appropriate solvents in any solvent ".It opens again《Encyclopadia Sinica chemissues one
Volume》P, page 315 also discuss road in this way：" ... after highly cross-linked, entire netted chain becomes a macromolecular, is not melted with insoluble
Property ".
The appearance of special chemicals breaches the final conclusion of this cross-linked structure substance " insoluble not melt ".This important breakthrough
Value be that it not only has resource value, and has economic value.Due to it, will can theoretically be identified as " cannot
Dissolving, it is impossible to melt " cross-linked structure high molecular material in a short period of time, be degraded under mild conditions and
Reconstruct, returns to oil ontology, even the polymerizable aromatic ring macromolecule component in belonging to the coal of cross-linked structure is also by mild degradation,
Make it possible that coal directly produces oil, broken the unrenewable final conclusion of oil.
The technology path of the present invention, is totally different from using oil aromatic hydrocarbons technology path, is totally different from coal-based methanol
Aromatic hydrocarbons technology path processed, be also differ completely from coal coking oil aromatic hydrocarbons technology path etc. exist " high investment, high energy consumption, high water consume,
The drawbacks of high pollution " four is high.
The technology path of the present invention is the coal chemical industry that coal dust is set up by " mild degradation Reconstruction Method ", there is Shi great Te
Point：When not water consumption, second is that without discharge, third, it is pollution-free, fourth, low energy consumption, fifth, flow is short, sixth, equipment is few, seventh, taking up an area
It is small, eigth, build soon, ninth, it is with good investment, tenth, it is low to coal quality requirements, it is the advanced production capacity of coal chemical industry.
The technology path of the present invention can make full use of China's rich reserves, cheap lignite, jet coal, dross coal
With weakly caking coal etc., the new technology of direct preparing aromatic hydrocarbon, new process are reconstructed by coal dust degradation using this special chemicals.
