Abstract
Biomass gasification systems including a biofilter assembly adapted to be disposed within a filter unit of a biomass gasification system are provided. The biofilter assemblies may be adapted to filter particulate matter from a producer gas flowing through the filter unit while allowing a remainder of the producer gas to pass through the biofilter assembly. The biofilter assembly may include a support structure and a biofilter disposed on the support structure and including a biomaterial adapted to be gasified in a biomass gasification reactor of the biomass gasification system.
Claims20
A biomass gasification system, comprising:
- a biofilter assembly configured to be disposed within a filter unit of the biomass gasification system and configured to filter particulate matter from a producer gas flowing through the filter unit while allowing a remainder of the producer gas to pass through the biofilter assembly, wherein the biofilter assembly comprises:
- a support structure;
- and
- a biofilter disposed on the support structure and comprising a biomaterial configured to be gasified in a biomass gasification reactor of the biomass gasification system;
- and
- a biofilter recycling system configured to direct the biofilter from the filter unit to the biomass gasification reactor when a usage of the biofilter is greater than a predefined usage limit.
A biomass gasification system, comprising:
- a feedstock preparation unit configured to process biomass to generate a biomass feedstock;
- a biomass gasification reactor configured to gasify the biomass feedstock in the presence of air to generate a producer gas;
- a filter unit comprising a biofilter configured to filter particulate matter from the producer gas to generate a reduced particulate producer gas, wherein at least a portion of the biofilter comprises a biomaterial configured to be gasified in the biomass gasification reactor;
- and
- a filter control system configured to identify when a usage of the biofilter is greater than a predefined usage limit based at least in part on a predefined amount of particulate matter adhered to the biofilter, a predefined time period, or a predefined flow of reduced particulate producer gas, or any combination thereof, wherein the biofilter is configured to be directed from the filter unit to the feedstock preparation unit or to the biomass gasification reactor when the filter control system identifies the usage of the biofilter to be greater than the predefined usage limit.
A method, comprising:
- directing a producer gas through a biofilter to remove particulates from the producer gas, wherein the biofilter comprises a biomaterial;
- and
- feeding the biofilter to a biomass gasification reactor to gasify the particulates.
