Problems solved by technology

However, due to the different types and indicators of the ultrasonic instruments used, the thickness of the extraction bottle, and random placement, the ultrasonic extraction effect of a certain component cannot be uniformly measured.
At present, there is no report on the use of ultrasonic extraction or auxiliary extraction of heavy oil after hydrothermal liquefaction reaction at home and abroad.

Embodiment 1

[0038] Take a certain amount of raw material dry matter and mix it with deionized water, so that in the obtained mixed solution, the mass percentage of raw material dry matter is 25%. The above mixed solution is charged into a hydrothermal liquefaction reactor.

[0039] In this embodiment, the hydrothermal liquefaction reactor adopts a batch reactor.

[0040] In this example, spirulina powder was used as raw material dry matter. The preparation method is as follows: Weigh 4°C frozen spirulina powder (screened to 200 mesh, ash content 5.7%), and thaw at 45°C.

[0041]Adjust the sealed reactor, fill it with nitrogen (volume concentration of 99.98%) to remove the air in the reactor, and make the pressure inside the reactor reach the initial pressure of 0.6MPA, start the agitator, and control the speed at 380rpm. After checking the air tightness , start the heating reaction. The temperature is controlled at 300° C., and the reaction time is 60 minutes.

Abstract

The invention relates to recycle of a heavy oil product in a biological crude oil preparation process, namely a method for preparing a heavy oil product from biological crude oil and increasing the yield by means of ultrasonic-assisted extraction. The method comprises the following steps: a, mixing a certain amount of dry raw material with deionized water so as to ensure that the mass percentage of the dry raw material in the obtained mixture is 15%-25%, and putting the mixture into a hydrothermal liquidation reaction kettle; b, regulating the sealed reaction kettle, introducing nitrogen so as to exhaust the air from the reaction kettle and simultaneously enable the pressure in the reaction kettle to be the initial pressure, starting a stirrer, and starting a temperature rise reaction after checking the air tightness; c, filtering and separating the mixture after the reaction is ended; d, mixing the separated residue oil with acetone of which the volume concentration is 98% at a ratio of 1:(10-12) (g:ml), and performing extraction by using an ultrasonic generator; e, filtering a mixed product after the extraction is ended, separating out the acetone phase, and recycling the acetone, thereby obtaining the heavy oil.

Description

technical field [0001] The invention relates to the recovery of heavy oil products in the bio-crude oil preparation process, and is a method for ultrasonically assisted extraction of bio-crude heavy oil products and improving yield. Background technique [0002] The world's oil resources are becoming increasingly depleted, and our living environment is deteriorating due to a large amount of vehicle exhaust and greenhouse gas emissions. Over the past few years, countries have been actively exploring energy sources and production technologies that can replace oil, with a view to solving the inevitable oil shortage problem as early as possible. Biomass is the only renewable energy source that can be converted into liquid fuels. The liquefaction of biomass into liquid fuels can not only alleviate the shortage of energy, but also reduce air pollution, protect the environment and comprehensively utilize resources. The development of biomass energy can help reduce the greenhouse e...
