Method for preparing synthetic gas by three-phase type biomass pyrolysis-gasification-catalytic reforming
ActiveCN102424359AImprove conversion utilizationHigh yieldHydrogenWaste based fuelCatalytic reformingChemical industry
The invention belongs to the technical field of energy chemical industry. The process for preparing synthetic gas by biomass pyrolysis and gasification is divided into three steps of biomass low-temperature pyrolysis, coke or semi-coke high-temperature gasification and crude synthetic gas / tar catalytic reforming. The three reaction steps are successively and continuously carried out in three relatively independent spaces of an upper pyrolysis hearth, a lower gasification hearth and a catalyst bed inside the same gasification reaction device so as to finally obtain the high-quality synthetic gas. The method provided by the invention has high carbon conversion rate, produces no secondary pollution and is simple to realize. In addition, required biomass is rich in reserves and can be regenerated, thus realizing integrated sustainable utilization of resource, energy and environment.
