Description
微細ダストを含む廃材Aと製紙スラッジBとが混在しており、該製紙スラッジBによって該廃材Aの微細ダストが吸着されてフロック化し、フロック化したダストが廃材Aに付着した主原料Cを、非酸化性雰囲気下で熱分解し、発生した熱分解ガスをスチームと反応させることを特徴とする、ガス化方法
に関する。
本発明のガス化方法では、原料として、微細ダストを含む廃材Aと製紙スラッジBとを混在させた主原料Cを用い、該主原料Cを非酸化性雰囲気下で熱分解し、発生した熱分解ガスをスチームと反応させる。
以下に示す微細ダストを含む廃材A及び製紙スラッジBを、以下の表1に示す組み合わせで混在させ、混合原料(主原料C)を準備した。該主原料Cを、ガス化装置内のアップドラフトガス化炉(炉下部層から上部層に向けて、灰化層、チャー層、揮発・熱分解層及び未反応原料層からなる4層の反応層を備えたガス化炉)に供給し、水蒸気と空気との混合気体雰囲気下で熱分解し、熱分解ガスを発生させた。なお、かかる熱分解の際、点火時にはプロパンガスを使用し、その後は廃材Aが自燃して熱分解が進行した。
A−1:板状・棒状廃木材混合材
(以下のA−2・A−3を略同量で混合した混合材、含水率:約22質量%、
粉体状微細ダスト(粒子径:約4mm)含有量:約7質量%)
A−2:板状廃木材(面積:約10cm2、厚さ:約5mm、含水率:約20質量%、
粉体状微細ダスト(粒子径:約2mm)含有量:約7質量%)
A−3:棒状廃木材(底面積:約1cm2、長さ:約50mm、含水率:約25質量%、
粉体状微細ダスト(粒子径:約6mm)含有量:約7質量%)
B−1:脱墨・排水スラッジ混合材
(以下のB−2・B−3を略同量で混合した混合材、含水率:約65質量%)
B−2:脱墨スラッジ
(古紙から脱墨古紙パルプを製造する脱墨処理工程のフローテーション工程で
発生したもの、含水率:約60質量%)
B−3:排水スラッジ
(製紙工程からの各種排水スラッジを集合処理したもの、
含水率:約70質量%)
Claims (5)
- 微細ダストを含む廃材Aと製紙スラッジBとが混在しており、該製紙スラッジBによって該廃材Aの微細ダストが吸着されてフロック化し、フロック化したダストが廃材Aに付着した主原料Cを、非酸化性雰囲気下で熱分解し、発生した熱分解ガスをスチームと反応させることを特徴とする、ガス化方法。
