content decreased (Agblevor et al. 1994). The equivalents of chlorine per equivalent of alkali or alkaline earth metals increased from 3.4 to 8.5 during this filtration. This suggests that the residual inorganics may be present as chlorides and that much of the chlorine may be in solution. Chloride ions in solution will have an adverse effect on corrosion of many metals, including stainless steels such as SS304. Compared to coal and many crude oils, biomass has a low sulfur content. Table 2 reveals that the small amount of sulfur in the biomass feed becomes concentrated in the char, rather than in the bio-oil. 3.0 PROBABLE CHEMICAL MECHANISMS OF...
