Title: Innovative Feeding System (IFS) for Biomass, SBIR Phase I Final Report

Abstract

Altex has identified the Innovative Feed System (IFS) to feed a range of biomass (eg. agricultural and forest residues) into pressurized reactors of up to 100 psig operating pressure with minimal gas leakage and pumping costs and at low power requirements versus conventional methods. IFS accomplishes these objectives by using a train of preformed biomass logs of 11-inches in diameter pushed into a similar size feeder tube to seal the pressurized reactor gases from the ambient. A hydraulic ram is used to periodically push the logs beyond the end of the feeder tube. The ram is then retracted and an additional log is loaded and then pushed forward to repeat this cycle. The friction between the train of logs and the tube wall keeps the logs in place as the piston is retracted. As the individual logs exit from the feeder tube to the pressurized zone ahead of the reactor, the logs are reduced to the needed particle size by either a two-step conventional or a single-step advanced sizer. Using steam at the higher pressure, size reduction power needs are substantially reduced and the reactivity of the sized biomass increased as a result of the steam explosion process when themore » pressure is reduced.« less
