Description
Technical field
The present invention relates to a kind of separation methods of oil-sand, belong to oil-sand separation processing technology field, refer in particular to oil-sand as original
The method that material uses high temperature pyrolysis separating treatment.
Background technique
The rapid growth of global economy, energy demand is increasing, and conventional gas and oil is no longer satisfied the national economic development
Demand, the unconventional resource of development and utilization oil-sand etc. has national energy security, enhancement of environment and economic stable development etc.
Important strategic importance.Oil-sand is widely distributed, resourceful, and the 32% of total amount can be adopted by accounting for about World's Oil and Gas Resources, as routine
The strategic supplement of the energy, plays important role in global energy structure.The whole world pours in a large amount of in the market in oil-sand
Fund is also that the breakthrough of oil-sand technology and innovation create condition, and have stimulated the development of oil-sand industry technology.Oil-sand can be one
Determine processing under process conditions and obtain oil product, suitable oil-sand processing and treating method is provided, realizes the " green of oil-sand resource
Color " exploitation and optimum use, can be relieved dependence of the China for imported crude oil, have good economic value and society's effect
Benefit.
Coal tar chemical composition in oil-sand is extremely complex, and based on condensed-nuclei aromatics and macromolecule hydrocarbon, viscosity is high, relatively
Molecular mass is big, and asphalitine, gum level are high, easily deposit, are adsorbed on sandstone interface, different according to adsorption form,
Oil-sand is divided into moistening, neutrality and glossy property.The method of oil-sand separation mainly has hot water wash method, solvent extraction, pyrogenation and carbonization
Method.
WATER-WASHING METHOD (such as patent CN104342185A, CN104342186A) by addition release agent process water, it can be achieved that
The efficiently separating of oil and sand in oil-sand, sand and water efficiently separate.Patent CN201610986447.X is soaked by using thin oil
Out and the technique of washing further increases oil-sand treatment effect in conjunction with the means of gravity settling separation.Solvent extraction is (as specially
Sharp CN104178202A) be also a kind of oil-sand separation effective ways, can overcome the problems, such as that resource utilization is low and environmental pollution.
Pyrogenation and carbonization method cracks oil-sand using high-temperature heating, the oil-sand separation suitable for oil content 6% or more.
Patent CN103289715A, CN103289716A provides a kind of oil-sand pyrogenation and carbonization method, uses oil-sand and coal as raw material,
Increase the production quantity of fuel gas by dosing coal, it is the oil-sand less than or equal to 30mm that this method, which is primarily adapted for use in particle size range,.Specially
Sharp CN104861999A discloses a kind of refining plant of compound thermal cracking of Atmospheric vacuum destructive distillation, subtracts destructive distillation again using first normal pressure destructive distillation
The technique of final high temperature destructive distillation realizes the separation of oil sands bitumen.CN106010613A discloses one kind and is pyrolyzed by little particle oil-sand
The method and apparatus for directly acquiring light oil obtains light-end products by being directly pyrolyzed little particle oil-sand, light before 350 DEG C
Matter oil yield is up to 90wt%.
In the experimental study stage, adaptability to raw material is poor for existing oil sand separation technology many places, and there are still many deficiencies, washes body
System's there are water consumptions big, wastewater treatment and environmental issue, solvent extraction solvent usage is big, at high cost, recycling is difficult, pyrolysis
Retorting technique energy consumption is high, equipment requirement is high, investment is big, and distance industrialization still needs to a lot of research work.
The purpose of the present invention is taking suitable process conditions to carry out thermal cracking oil-sand, cracked after separating treatment
Gas, cracked oil and solid product, provide that a kind of adaptability to raw material is wide, the reasonable technique side using oil-sand of equipment simple possible
Method.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the invention to develop a kind of side for oil-sand thermal cracking separating treatment
Method, it is characterised in that：
Oil-sand of the present invention can be moistening, neutrality and glossy property oil-sand, and particle diameter is 0.5m~5mm,
Oil content is 10w%~25w%.
Above-mentioned oil-sand thermal cracking separating treatment can carry out in general simple reaction kettle device, cracking temperature 400
~450 DEG C, 5 DEG C/min~8 DEG C of heating rate/min, the reaction time is 1.0~2.0 hours.
After the method separating treatment of high temperature pyrolysis, the separation of oil-sand component can be made more thorough, separating effect obtains
It is the effective ways that oil-sand separation utilizes to significantly improving.It can be obtained product after separating treatment, cracking gas 10w%~
15w%, cracked oil 5w%~15w%, solid product (sandstone, coke) 75w%~80w%.
