Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, a composite coal hydrogenation refinery reactor of the present invention includes a gasifier 1, a reactor 2, a high-temperature cyclone separator 3, an oil-gas separation tower 4 and a carbon monoxide conversion system 5, and in the gasifier 1 There is an integrated start-up burner 6 in the middle, and four coal burners 7 are arranged in the middle and lower part of the gasifier 1. The four coal burners 7 are on the same horizontal plane and are evenly distributed along the circumference of the gasifier 1. 1 is provided with four semi-coke inlets 8, the four semi-coke inlets 8 are on the same horizontal plane and evenly distributed along the circumference of the gasifier 1, and a slag collector 9 is provided at the bottom of the gasifier 1, and the slag collector 9 The slag outlet 10 extends to the outside of the gasifier 1, a pressure sensor 11 is provided at the middle and upper part of the gasifier 1...

Embodiment 2

[0021] A method of oil refining comprises the steps of:

[0022] (1) Oxygen and diesel oil enter from the integrated start-up burner 6, the flow rate of diesel oil is 0.3-1.0Kg / s, the flow rate of oxygen is 0.2-0.5kg / s, and the ignition is carried out through the igniter on the integrated start-up burner 6 , when the temperature in the gasifier 1 reaches 800-1000°C and the pressure reaches 0.6-1.0 MPa, start to add coal powder and oxygen;

[0023] (2) When adding pulverized coal and oxygen, first add through the coal burner 7 next to the integrated start-up burner, and then add through the coal burner 7 facing the already added coal burner. The integrated start-up burner for the combustion of pulverized coal exits. After the integrated start-up burner exits, the other coal burners 7 continue to be added one after another. 1.00kg / s;

[0024] (3) When the temperature in the gasifier rises to 1450-1650°C and the pressure rises to 3.2-3.6Mpa, the pulverized coal gasification react...

Abstract

The invention belongs to the technical field of pulverized coal pyrolysis oil refining device, and particularly relates to a composite coal hydrogenation oil refining reactor and an oil refining method, mainly aiming at solving the problems of high resource consumption, serious environmental pollution, high cost and the like of existing coal hydrogenation pyrolysis reaction. The composite coal hydrogenation oil refining reactor disclosed by the invention comprises a gasifier, a reactor, a high-temperature cyclone separator, an oil-gas separation tower and a carbon monoxide conversion system, wherein the top of the gasifier is communicated with a reactor; the top of the reactor is communicated with the high-temperature cyclone separator; a bottom outlet of the a high-temperature cyclone separator is communicated with a semicoke inlet of the gasifier through a semicoke pipeline; a top outlet of the high-temperature cyclone separator is connected with an oil-gas inlet of the oil-gas separation tower through a gas pipe; a gas outlet in the top of the oil-gas separation tower is connected with an inlet of the carbon monoxide conversion system; an outlet of the carbon monoxide conversion system is connected with a hydrogen compressor; and an outlet of the hydrogen compressor is connected with one section of hydrogen inlet and two sections of hydrogen outlets.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal pyrolysis oil refining equipment, and in particular relates to a composite coal hydrogenation oil refining reactor and an oil refining method. Background technique [0002] Flash Hydropyrolysis of Coal (FHP for short) is a new coal conversion technology recently developed abroad. Under the pressure of 3-10MPa, coal is pyrolyzed in a hydrogen atmosphere, and the reaction is completed in a short residence time of only a few seconds, thereby maximizing the extraction of benzene, toluene, xylene (BTX), phenol, cresol and xylene from coal Phenol (PCX) and other liquid light aromatics (HCL) and light oil, etc., at the same time to obtain methane-rich high-calorific value coal gas, the total carbon conversion rate of the gas and liquid products can reach about 50%, which is known internationally as A third coal conversion technology between gasification and liquefaction. But the current coal-to...
