Abstract

The invention provides a device for preparing catalytic slurry of hydrogenated light coal-based heavy raw materials. The device is a preparation device for hydrogenation and light coal-based heavy raw material catalytic slurry with an underground adiabatic coal-based heavy raw material slaking device as the core. The device of the present invention can use coal-based heavy raw materials from a wide range of sources, has simple and safe operation procedures, and is environmentally friendly. The device of the present invention comprises (1) initial coal-based heavy raw material catalytic slurry preparation unit; (2) aging unit; (3) three removal unit; (4) homogeneous aging unit four basic device units.

Description

technical field [0001] The invention provides a device for preparing stable hydrogenated light coal-based heavy raw material catalytic slurry. The device of the present invention may include the following units: initial coal-based heavy raw material catalytic slurry preparation unit; aging unit; dehydration, degassing and sand removal separation unit; homogeneous aging unit. Background technique [0002] In the hydrogenation and lightening method of coal-based heavy raw materials, the preparation of high-concentration coal-based heavy raw material catalytic slurry with excellent fluid transport performance is not only a prerequisite for improving the efficiency of the heavy raw material hydrogenation and lightening method, but also The composition and structure of the hydro-lightening unit will be simplified, thereby improving the operability of the hydro-lightening unit. Therefore, the device for preparing catalytic slurry for hydrogenation and lightening of coal-based hea...
