Proximate analysis• Place biomass sample on a scale in an oven filled with inert gas• Heat up to 110˚C → moisture evaporates• Measure weight loss → moisture content• Wet basis:• w = (wet weight-dry weight)/wet weight• Dry basis:• u = (wet weight-dry weight)/dry weight• Conversion:• w = u/(1+u) u = w/(1-w) u > w/ <strong>Mechanical</strong> <strong>Engineering</strong> 18-11-2011 PAGE 18
