A substance dual fluidized-bed gasification apparatus and process raw natural gas

The present invention provides one kind of double-gasifying biomass and natural gas process apparatus, comprising: a combustion unit heating a carrier, pyrolysis unit, biochar / carrier separating and conveying means, and tar Methane loopback means the illustrates pyrolysis unit connected to the combustion heating unit vector biochar / carrier separating and conveying means, and tar methane loopback means biochar invention obtained while achieving the remaining ingredients as converted into methane gas, methane content in the pyrolysis product about 10%, reducing the subsequent synthesis pressure, the tar in the pyrolysis gas as fuel in a fluidized bed using a double, double bed to avoid other low temperature combustion can not occur when the bio-char combustion at a high temperature stable base metal cause slagging problems, so that the furnace temperature control is very flexible, the present invention makes full use of products of different pyrolysis of biomass, biomass can achieve a variety of processing, such as adaptive wide.
