Description

technical field [0001] The invention relates to a novel spouting circulating fluidized bed wood rapid pyrolysis device and a process method, belonging to the technical field of biomass regeneration and utilization and its energy conversion. Background technique [0002] Seeking and developing renewable and clean energy including wood resources is one of the most important issues facing the world in the 21st century. As one of the main forms of biomass, wood is an important part of renewable resources in nature and occupies a very important position in biomass resources. Reasonable conversion of wood into energy or chemical raw materials has important practical significance and broad prospects for reducing the consumption of conventional fossil resources, making up for the shortage of chemical raw materials, reducing environmental pollution, and realizing sustainable development of resources, environment and society. [0003] Fast pyrolysis technology, which can convert low-...
