Embodiment Construction

[0026] The present invention will be further described below using the accompanying drawings and examples.

[0027] Such as figure 1 As shown, the recovery process of the microwave absorption and desorption oil shale dry distillation gas light oil of the present invention comprises: simultaneously setting the first synchronous circulation tank 1 and the second synchronous circulation tank 2 with the same structure, the first synchronous circulation tank 1 and the second synchronous circulation tank The second synchronous circulation tank 2 is equipped with activated carbon or activated carbon fiber fillers for absorbing oil vapor in the gas gas. The first synchronous circulation tank 1 and the second synchronous circulation tank 2 are respectively equipped with microwave heating generators 6, and the microwave heating generators 6 receive The microwaves emitted by the microwave heating controller 5 are sent into the tank. The first synchronous circulation tank 1 and the second...

Abstract

The invention discloses a recovering process of light oil of dry distilled gas of oil shale by virtue of microwave adsorption and desorption. The recovering process is characterized in that a first synchronous circulation tank and a second synchronous circulation tank with a same structure are simultaneously arranged, activated carbon or an activated carbon fibrous filler used for adsorbing oil steam in gas is charged in each tank, each tank is provided with a microwave heating generator used for sending launched microwaves in each tank, and the two tanks share one indirect cooling oil collecting tank, one light oil storage tank, one microwave heating controller, one gas storage tank, one cooling tower and one circulating pump; when the first synchronous circulation tank adsorbs gas oil steam, the second synchronous circulation tank carries out microwave heating desorption and regeneration of the activated carbon or the activated carbon fibrous filler; when adsorption of the filler in the first synchronous circulation tank reaches saturation, feeding of the gas is stopped, the second synchronous circulation tank is started to adsorb the gas oil steam at the moment, while the first synchronous circulation tank starts to carry out microwave heating desorption and regeneration of the activated carbon fibrous filler, the steps are repeatedly and alternatively carried out, and the light oil is continuously recovered from the dry distilled gas.

Description

technical field [0001] The invention relates to the technical field of oil shale dry distillation and oil refining, and relates to a recovery process for microwave absorption and desorption of oil shale dry distillation gas light oil. Background technique [0002] Oil shale carbonization, that is, heating oil shale to the required temperature in an air-isolated environment, so that the kerogen undergoes pyrolysis reaction, and generates carbonization products-shale oil and carbonization gas. Shale oil can not only be used directly for marine use The liquid fuel used by turbines can also be produced through rectification process to produce liquid fuels such as gasoline and diesel. At present, the recovery of shale oil in the industry generally adopts the method of condensing and separating the retorted oil and gas, and cooling the retorted oil and gas to make the shale oil become liquid and precipitate, and the rest is non-condensable gas. Therefore, the lower the temperatur...
