บทคัดย่อ

Enhancing hydrogen yield and tar reduction in product gas from wood pyrolysis is investigated using high temperature steam reforming. The aim of this study is to determine the influence of reforming temperature with and without steam injection and retention time on the reforming performance, such as hydrogen conversion and tar reduction. This study is concentrated on highly temperature range between 900 ฐC to 1200 ฐC. Based on the experimental results, the reforming temperature has remarkable affect to hydrogen production and tar reduction. Increasing in reforming temperature increases the hydrogen content and decreases the tar content. For dry reforming condition, the yields of hydrogen increase more than two times over the reforming temperature tests. The amount of tar is reduced up to 90% at reforming temperature of 1200 ฐC. These affects are heightened when steam is injected during reforming process. The H2/CO ratio is increased from 0.8 to 1.2 at temperature of 1200 ฐC and further increased to 1.7 when steam is introduced. The retention time clearly indicates the influence on H2 yields, increasing of retention time results in higher H2 concentration on the entire temperature range. It could be concluded that the retention time promote the production of H2 and might be come from the reduction of tar quantity. Tar quantity is reduced with higher temperature and longer retention time of reforming process. Copyright ฉ 2012 American Scientific Publishers.
