摘要:
The present invention provides a method (1) and system for the removal of tar from a synthesis gas (10) using a chemical loop (23). A first reactor (20, 55) is fed with mineral particles and the synthesis gas. The mineral particles catalyse the tar in the synthesis gas to produce a mixture comprising hydrogen and a mineral carbonate. A second reactor (15, 70) is fed with oxygen and the mineral carbonate. The oxygen reacts with the mineral carbonate to produce a flue gas (25) comprising carbon dioxide and mineral particles, which are then separated and the mineral particles are recycled to the first reactor.
