Thermal Catalytic Syngas Cleanup for High-Efficiency Waste-to-Energy Converters
Abstract
The objective of this project was to develop a robust, efficient, and compact syngas-cleaning system that would complement small-scale countercurrent, or updraft, gasifier technology for waste-to-energy conversion. Results show that the concept of using a countercurrent gasifier coupled with a catalytic tar-reforming stage can be a viable route to meet the performance targets established for a forward operating base waste-to-energy converter. An analysis of data from prototype testing shows that the concept could exceed the conversion efficiency target of 50% with relatively straightforward improvements to sensible heat recovery from the clean syngas leaving the tar reformer. This projects testing has also substantiated the operational benefits associated with countercurrent gasification. The prototype produced a clean syngas that will minimize the frequency and severity of routine maintenance, and after passing through the system, the processed waste was fully converted to inert ash, thereby achieving the volume reduction and sanitized ash goals.
