High temperature cleaning of producer gas from biomass gasification has been investigated with a granular filter. Field tests were performed for several hours on a single filter element at about 550 degrees C. The results show cake filtration on the granular material and indicate good filtration of the biomass gasification producer gas. The relatively low pressure drop over the filter during filtration is comparable to those of bag filters. The granular filter can operate with high filtration velocities compared to bag filters and maintain high efficiency and a low residual pressure. This work is a part of the BioSOFC-up project that has a goal of utilizing the producer gas from the gasification plant in a solid oxide fuel cell (SOFC). The BioSOFC-up project will continue to the end of 2007.
利用颗粒过滤器对生物质气化产生的原料气进行高温净化的研究已经展开。在约550摄氏度的温度下，对单个过滤元件进行了数小时的现场测试。结果表明颗粒材料上形成了滤饼过滤，这表明生物质气化原料气具有良好的过滤效果。过滤过程中过滤器上相对较低的压降与袋式过滤器相当。与袋式过滤器相比，颗粒过滤器能够以较高的过滤速度运行，并保持高效率和低残余压力。这项工作是BioSOFC-up项目的一部分，该项目的目标是在固体氧化物燃料电池（SOFC）中利用气化厂产生的原料气。BioSOFC-up项目将持续到2007年底。
