Summary
Fluidized bed gasification of solid recovered fuels (SRFs) is technically feasible. This process yields valuable syngas for energy applications, confirming the technology
Area of Science:
- Chemical Engineering
- Waste Management
- Energy Conversion
Background:
- Solid recovered fuels (SRFs) are co-products of recycling processes.
- Efficient conversion of SRFs into energy is crucial for waste management and resource recovery.
Purpose of the Study:
- To evaluate the technical feasibility of fluidized bed gasification for three different SRFs.
- To characterize the syngas produced and assess the process's viability for energy applications.
Main Methods:
- Pelletized SRFs were gasified in a pilot-scale bubbling fluidized bed reactor.
- Tests were conducted in gasification and co-gasification modes under steady-state conditions.
- Syngas, bed material, and entrained fines were comprehensively analyzed.
Main Results:
- Fluidized bed gasification demonstrated technical feasibility for the tested SRFs.
- The process yielded syngas of valuable quality for energy applications.
- Material and substance flow analysis supported the feasibility assessment.
Conclusions:
- Fluidized bed reactors offer flexibility for gasifying various waste streams, including in co-gasification.
- The tested SRFs can be technically converted into usable syngas via fluidized bed gasification.
- The process is viable for energy recovery with appropriate plant design.
