Abstract

A moving bed granular filter (MBGF) was tested for the removal of particulates from a high temperature producer gas of a biomass gasifier. As a result of problems in high temperature isokinetic sampling, the efficiency of the MBGF was not accurately determined. However, it appears that the inlet concentration to the MBGF was in the range of 2 to 30 g/m3, with the most likely level being around 5 g/m3. There are several indications clues that indicate that the MBGF was working at relatively high efficiency, although this could not be quantified. Particulate analysis under the scanning electron microscope (SEM) showed no traces of silicon, a major component of the filter media, which disproved a concern that the MBGF was adding dust from the granular media to the producer gas stream. The SEM results also showed that the MBGF effectively removed most of the largest particulate from the entering gas stream, which suggests filtration to some degree. Additionally, an analysis of the waste MBGF filter media showed that up to 5 g/m3 of dust was being removed from the entering stream. All of these results point toward a reasonable level of filtration.
