Gasification of sawdust and wood chips in a fixed bed under autothermal and stable conditions

The high potential in Colombian agroforestry residues can be exploited through gasification; however, biomass pretreatment must be minimized to increase process efficiency. In this article, the gasification of woodchips and sawdust mixtures (0, 30, 70, and 100% of sawdust, wt%) with three air veloci...
