Description
Technical field
The invention belongs to and from resinous shale, extract the shale oil technical field, relate to a kind of oil shale distillation system.
Background technology
Resinous shale is a kind of important potential energy source, and reserves are huge, and its reserves are converted to that thermal value is only second to coal and second of row in fossil oil.If it is converted to shale oil, oil shale reserves in the world is about 4,750 hundred million tons, is equivalent to the several times that present world natural crude oil is verified workable reserve.The Application and Development of resinous shale has more than 200 year history, and the development and use of the resinous shale energy mainly are to produce shale oil.
During the World War II, because the petroleum demand amount increases severely, oil price soars, and resinous shale exploitation upsurge had once been risen in many countries.And in peacetime after World War II, because cheap natural oil is found and a large amount of exploitation, oil price descends significantly, makes the oil shale industry of firm rise be in stagnant condition.
In recent years, owing to oil, be becoming tight natural gas source day, imbalance between supply and demand is more and more outstanding, and price is surging, not only to the Economic development build-up of pressure, and the political economy situation of influence country.So countries in the world are paid attention to again the correlation technique of producing shale oil from resinous shale.
Resinous shale institute oily total amount is also more than tellurian oil and gas summation, if extractive technique can the commercialization extensive application, can solve the crisis of resource of oil and gas in considerable time.
In the patent document of the disclosed US4058905 of United States Patent Office (USPO) and US3302936 and the CN87102476 of China national Patent Office, disclosed a kind of dry distillation method of oil shale.This method comprises the steps such as collection of shove charge to resinous shale, heating, cooling, shale retorting gas; The selected processing unit of this method for destructive distillation is a kind of annular carbonization furnace with horizontal rotation bed, utilizes the realization of gas thermophore to the heating of raw shale oil and realizes the oil shale distillation process.
