Description
先ず、本発明において、バイオマスとは、以下のFAO(国連食糧農業機関)の定義に準じて定義される。
〜30%)に乾燥する場合を例に説明したが、木質系バイオマス原料の含有水分量が少ない木質系バイオマス原料を用いる場合には、乾燥機1で乾燥せずに、直接、加熱処理機2で加熱してもよい。
図1に示すコークス製造プロセスを用いて、杉の廃材を木質系バイオマス原料とし、乾燥機1により、原料中の水分量が30%になるまで乾燥した後に、加熱処理機2により、表1に示す加熱温度、水蒸気添加有無条件で加熱処理をした後、破砕機3により、粒度が10mm以下になるように破砕処理を行った。
粉砕した木質系バイオマス原料を、石炭に対して質量比で2%混合した後、コークス炉5に装入して、1200℃で18時間乾留を行った。
2…加熱処理機
3…破砕機
4…石炭混合機
5…コークス炉
6…ガス冷却器
7…油分回収装置
8…コークス燃料混合装置
9…コークス燃料供給装置
Claims (2)
- 木質系バイオマス原料を300超〜400℃で加熱処理し、かつ該加熱処理において水蒸気を添加し、該木質系バイオマス原料から熱分解により生成した油分を分離、回収し、残部の木質系バイオマス原料を、所定粒度に粉砕した後、石炭と該木質系バイオマスとを混合してコークス炉に装入して乾留し、コークスを製造することを特徴とする木質系バイオマスを用いたコークスの製造方法。
- 前記熱分解により生成した油分が、アセトール、プロピオン酸メチル、フェノール類及びクレゾール類のうちの1種又は2種以上からなることを特徴とする請求項1記載の木質系バイオマスを用いた高炉用コークスの製造方法。
