Title:
OXYGEN CARRIER/CARBON CARRIER-BASED BIOMASS CHEMICAL LOOPING GASIFICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/137056
Kind Code:
A1
Abstract:
An oxygen carrier/carbon carrier-based biomass chemical looping gasification method and device. The device comprises an air reactor (1), a second separator (5-2), a calcination reactor (3), a first separator (5-1), and a gasification reactor (2) connected in sequence. The top of the calcination reactor (3) is communicated with an air inlet of a third cyclone separator (4-3). A solid particle discharge port on the bottom of the third cyclone separator (4-3) is communicated with the calcination reactor (3). An exhaust pipeline of the third cyclone separator (4-3) is communicated with the air inlet on the bottom of the calcination reactor (3) by means of a valve. An air outlet of the gasification reactor (2) is communicated with the air inlet of a first cyclone separator (4-1). The solid particle discharge port of the first cyclone separator (4-1) extends into the bottom in the gasification reactor (2) by means of the pipeline. The air outlet of the gasification reactor (2) is communicated with the air inlet of a second cyclone separator (4-2). By combining respective advantages of the chemical looping gasification and CaO absorber methods, the method optimizes the existing chemical looping gasification process, improves the energy utilization efficiency of a biomass, and effectively separates CO 2 generated by a reaction.
