Abstract

The invention discloses a heterogeneous catalytic gasification reactor for coal. The heterogeneous catalytic gasification reactor comprises a feeding system, a gas system, a heating system, a solid-gas reactor and a gas-gas reactor. The feeding system feeds solid reactants or catalysts into corresponding compartments of the solid-gas reactor in real time according to an airflow blowing and carrying principle, a feeding flow can be controlled by adjusting a gas flow and the propelling speed of a blower, and different types of blowing gas are selected according to experimental purposes and soliddensity. The gas system comprises a main gas path, secondary gas paths and blowing gas paths, and gas can be fed from different gas paths according to gas types determined by the experimental purposes. The solid-gas reactor and the gas-gas reactor can respectively conducting heating at different temperatures as required; and the heating system adopts a two-section vertical pipe type electric heating furnace, enough heating space and a constant temperature zone are provided for respectively heating the solid-gas reactor and the gas-gas reactor, and the solid-gas reactor and the gas-gas reactorcan be heated to test temperature and controlled at constant temperature. The heterogeneous catalytic gasification reactor can be used for generating solid and gas products on line.

Description

technical field [0001] The invention relates to the technical field of scientific research on coal catalysis, pyrolysis, gasification and combustion engineering, in particular to coal pyrolysis gasification polygeneration process. Background technique [0002] Coal is the foundation of China's energy supply, but it cannot be used efficiently and cleanly because it is prone to produce harmful gases, solid waste residues and wastewater that affect the environment during the energy utilization process. Therefore, studying its efficient and clean conversion technology is the fundamental research direction of my country's energy. The pyrolysis, gasification and combustion of coal are the basic forms of its utilization, and the catalytic process makes these processes more clean and efficient. In order to quickly, accurately and comprehensively study and master the comprehensive utilization of coal, it is necessary to combine these reaction processes organically. A reactor, through...
