A carbonization apparatus for coal with wide particle size distribution, a carbonization apparatus unit, and a carbonization method using the apparatus. The apparatus includes a char discharge outlet, a combustion heating chamber, a coal feeding inlet, a pyrolysis gas exhausting pipe, and two partition plates between which a pyrolysis gas channel is formed. Orifices are provided on the partition plates to form a gas flow path from the fuel bed to the pyrolysis gas channel. The pyrolysis gas channel in the carbonization apparatus permits the gaseous products generated from coal pyrolysis to flow out in a timely manner.

An integrated apparatus and method for co-production of carbon and hydrogen by biomass cascade pyrolysis-microwave gasification are provided. The apparatus includes an integrated reaction system, an internal and external radial energy supply system, and a product separation and collection system. The method includes firstly performing low-temperature pyrolysis on feedstock to greatly improve its absorbing property, and then preparing co-production of a hydrogen-rich gas and a porous carbon product by microwave gasification and online reforming, where the combustion of the pyrolysis gas provides heat for feedstock drying and its low-temperature pyrolysis reaction; performing separation and purification on the hydrogen-rich gas to prepare a high-purity hydrogen product, where the separated gas serving as a gasification agent returns for gasification reaction. By using multi-system collaborative integrated designing, the low-temperature pre-pyrolysis improves microwave product quality and reaction efficiency while greatly reducing high-quality electric energy consumption, and supplying heat by self-made low-quality thermal energy recycling.
