Problems solved by technology

Although in view of the seriousness of the "greenhouse effect", European and American countries have begun to study coal-based near-zero-emission polygeneration systems in recent years, but due to the stable chemical properties of carbon dioxide, such coal-based near-zero-emission polygeneration systems cannot be realized in the production process Carbon dioxide emission reduction can only be solved by capturing and sequestering, but this method is costly and cannot really reduce carbon dioxide in volume. In the long run, it is only an expedient measure

Embodiment 1

[0132] Take dry coal powder with a particle size of less than 75 μm, configure it into a 10-30 wt% slurry, then add a potassium carbonate catalyst with a dry coal mass fraction of 10%, and stir evenly;

[0133] Turn on the high-pressure pump 2 to pressurize the whole device with water until the pressure in the reactor rises to 25MPa or 30MPa, then pump the slurry into it. After the system pressure is stabilized, turn on the heating power of the reactor and set the central temperature of the reactor to 650°C or 550°C, set the preheating temperature of the coal-water slurry to a maximum of 300°C. The preheated slurry reacts quickly in the reactor, and the residence time is 30 seconds to 1 minute. The reaction product is cooled to 80°C by the cooler 5 and enters one of the buffer tanks 8. After the buffer tank is full, switch to another buffer tank, and then depressurize the full buffer tank. The reaction product after depressurization Enter the first separator 6 for gas / liquid-...

Embodiment 2

[0137] Grind the sunflower stalks and microalgae residues to below 80 meshes, make a slurry with a concentration of 20wt% with water, add it to the slurry storage tank 1, and then add a K-Ni composite catalyst loaded on a carrier with a dry powder mass fraction of 5%, Stir well.

[0138] Turn on the high-pressure pump 2 to pressurize the system with water until the system pressure rises to 25MPa, then pump the slurry in. After the system pressure is stable, turn on the heating power of the reactor 4 and set the central temperature of the reactor to 350°C or 400°C , set the pulp preheating temperature up to 200°C. The preheated slurry reacts rapidly in the reactor, and the residence time is 1-10 minutes. The reaction product is cooled to 80°C by the cooler 5 and then enters the first separator 6 for gas / liquid-solid separation, and the gas product obtained is discharged from the top opening of the separator, and a safety valve can be set on the gas pipeline according to the ne...

Embodiment 3

[0142] The residual oil obtained by crude oil distillation under reduced pressure, together with water and surfactants, is formulated into a slurry with a concentration of 30-40wt%, which is added to the slurry storage tank 1, and then 15% of the weight of the residual oil is added to be loaded on the carrier K-Ni composite catalyst, stir evenly.

[0143] Turn on the high-pressure pump 2 to pressurize the system with water until the system pressure rises to 28MPa, then pump the slurry in. After the system pressure is stabilized, turn on the heating power of the reactor 4, set the central temperature of the reactor to 600°C, and set The maximum pulp preheating temperature is 200°C. The preheated slurry reacts rapidly in the reactor, and the residence time is 2 minutes. The reaction product is cooled to 80°C by the cooler 5 and then enters the first separator 6 for gas / liquid-solid separation, and the gas product obtained is discharged from the top opening of the separator, and...

Abstract

The invention relates to a comprehensive method for utilizing a carbon-contained organic matter, comprising a high-pressure hot water / supercritical water gasifying sub-method and a poly-generation sub-method, wherein the high-pressure hot water / supercritical water gasifying sub-method is continuously carried out by the decompression continuous discharge of a reaction product. The decompression continuous discharge is realized by adopting at least two buffer tanks which are operated in parallel connection or at least one decompressing valve. The invention converts the carbon-contained organic matter into a clean energy chemical product, such as methane, and the like and / or clean electricity by coupling the high-pressure hot water / supercritical water gasifying sub-method, the poly-generation sub-method, an alga carbon absorbing sub-method and / or a composite energy source hydrogen preparation sub-method to form an ecological cycle mode for the development and utilization of carbon-contained organic matter resources. The invention also provides a comprehensive system for implementing the comprehensive method.

Description

Field of Invention [0001] The present invention relates to coal chemical industry, and more particularly, the present invention relates to an integrated method of utilizing carbon-containing organic matter coupled with other methods and a system for implementing the integrated method. Background technique [0002] The bottleneck problems of resource shortage and environmental pollution are two hot issues in the world today. With economic development and industrial progress, the continuous acceleration of urbanization and the improvement of people's material life, on the one hand, the demand for disposable energy continues to grow, and on the other hand, the amount of organic wastes such as industrial waste and urban domestic waste also increases rapidly. , resulting in a huge waste of resources. The new energy technology should not only be able to meet the growing needs of human economic development in terms of technology and reserves, but also meet the environmental requir...
