Description
本発明の一つの目的は、水から水素ガスを製造する新規方法を提案することである。
本発明により、スラグ及び炭素質フラックスに水を加えて、水を熱化学分解することにより水素を生産することを含む、水から水素ガスを製造する新規方法が提供される。
炭素質廃棄物及び触媒フラックスの存在下に水とスラグの反応により水素ガスを生産するための新規方法が開発された。水素ガス生成の全体の反応は下記の式で表される:
式中Aはシステムに加えられる水の量、xはフラックス中の利用しうるCの量、yはスラグ中のFeOであり、zはCOと水の間の反応によるCO2の生成量である。この新規方法において、スラグは吸熱的水分解反応に相当な熱(sensible heat)を供給するのみならず、水素と酸素ガスの間の逆反応も防ぐ。スラグ中のFe及び低酸化度のFeは生成したガス混合物中の酸素ガスと反応して、Fe2O3を形成し、それにより酸素の熱力学的活性を減少させる。脱酸素剤として働くことが出来る種々のタイプの廃棄物は、水素ガスの生産を改善するためのフラックスとして使用することができる。
溶融したスラグの顕熱(sensible heat)は水の熱化学分解に使用することができる。この方法において、スラグは熱源として働き、またスラグ中の脱酸素成分(Fe,FeO)の一部は反応(2)を介して発生し始めた(nascent)酸素と反応することにより分解反応(1)に関与している:
石炭微粉、粉コークスなどのような炭素質及び他の工場廃棄物を、水の熱分解による水素生成を促進する脱酸化剤として使用することができる。水と炭素との間の反応は次の通りである:
試料採取口(5)、コンデンサータンク(7)及び収集タンク(11)から採取したガス試料の典型的な分析結果を以下に示す。
(容量%による濃度)
LD#2製鉄所のスラグピットにおいて試験を実施するために設計され、製作された設備を図4に示す。標準的な(段階的)手順を以下に記述する:
検体採取口(5)から採取したガス試料の典型的な分析結果を以下に示す:
Claims (4)
- 溶融スラグに、炭素質のフラックスと水とを加えて、水素を生産する方法であって、
該スラグ100g及び該フラックスの炭素10gあたり該水を40ml以上加える、方法。 - 前記水を、前記フラックスの炭素10gあたり100ml加える、請求項1に記載の方法。
- 系の酸素分圧を減少させて、水素ガスの形成速度を増大させる、請求項1又は2に記載の方法。
- 前記溶融スラグの表面に前記と炭素質のフラックスを散布し、得られた溶融材料の表面に水を散布する、請求項1から3の何れか1項に記載の方法。
