Biomass self-gasification

摘要

Model Results 1. Methane can be produced via gasification and with high efficiencies (up to 66%) 2. An autothermal gasifier is possible without use of O2/air at 700℃ and pressures of 20-35 bar 3. Improved or new CO2 separation technology is needed with low energy requirements Experimental Results 1. Minerals/ash impregnated in biomass accelerate gasification at the targeted temperature (700℃) enough to establish self-gasification 2. K_2CO_3 in char catalyzes the formation of methane towards equilibrium amounts UNIVERSITY OF TWENTE.
