Abstract

The invention discloses a system for producing oil by hydrotorting oil shale under increased pressure. The system comprises a dry distillation furnace (1), an oil shale stock bin (2), an oil storage tank (3), an oil-gas separator (4), a hydrogen separator (5), a hydrogen-rich gas tank (6), a gas heater (7), a vaporized fuel cabin (8), a combustible gas tank (9), a heat exchanger (10), a gasification furnace (11) and a conveying device (12). In a process for producing oil by hydrotorting oil shale under increased pressure by using the system, gas produced by dry distillation is separated through the hydrogen separator, produced hydrogen-rich gas is returned into the dry distillation furnace after being heated by the gas heater, and produced dehydrogenated gas and combustible gas produced by gasification in the gasification furnace are introduced into the gas heater as fuels. Oil shale particles are produced into oil through dry distillation in a hydrogen-rich atmosphere, so that organic matters are prevented from being carbonized due to lack of hydrogen, and the oil yield of the oil shale is increased; the dehydrogenated gas and the combustible gas are introduced into the gas heater as fuels, so that the energy utilization ratio is increased.

Description

technical field [0001] The invention belongs to the technical field of oil shale resource utilization, and relates to an oil shale pressurized hydrogenation dry distillation system and process. Background technique [0002] Oil shale, also known as "solid petroleum", is an unconventional oil and gas resource with huge reserves. Shale oil with properties similar to natural petroleum can be obtained by heating in a retort device at 400-600°C. The S has been used as a very important petroleum supplementary energy source. At present, the world's proven shale oil reserves are more than 400 billion tons (converted according to oil shale in-situ reserves), which is much higher than the world's proven recoverable crude oil reserves, and this figure will increase with the further exploration of oil shale resources. my country is a country with large reserves of oil shale resources. According to the results of national oil shale resource evaluation from 2004 to 2006, my country's oil ...
