摘要:
A system for gasification of a carbonaceous material and recycling char or solids from a gasifier is disclosed. The recycling system may include a standpipe that receives a solids stream from a separator, the standpipe generating a pressure differential across a bed of accumulated char, thereby producing a bottoms stream having a greater pressure than the inlet solids stream. The recycling system may also include a holding vessel that receives the bottoms stream and a fluidized-bed distribution vessel that receives char from the holding vessel and is configured to provide a continuous and precise flow of recycled char to the gasification reactor.
