Abstract:

Autothermal gasification was carried out to evaluate the performance and the flexibility of a pilot plant based on an updraft gasifier and a gas cleaning section coupled with a section for hydrogen enrichment. The tests were performed by feeding the gasifier with almond shells and using a steam/air mix as gasification medium. The main operating parameters, such as process flow rates, temperature profile along the reactor, temperature and pressure control throughout the downstream piping, were continuously monitored. Producer gases were sampled along the piping for on­line and off­line analysis. The producer gas contained 21.1% H2; 22.8% CO; 13.4% CO2, 1% CH4, corresponding to a heating value (LHV) of 5.7 MJ/Nm3. The gasification proceeded without major problems: it was stable and produced a syngas that was efficiently cleaned by scrubbing it with biodiesel and by filtering it with coalesce filters.
