Description
(1)第1区域において高くとも350℃の初期供給温度を有する供給ガス混合物を、第1の触媒の存在下で反応温度範囲内の温度に加熱し、
(2)加熱された供給ガス混合物をこの反応温度範囲内で第2の区域において第2の触媒と接触させる、
各工程を有してなるプロセスにより達成される。
上部にガスの入口を、下部にガスの出口を有する、長さ450mm、直径12mmの石英製管型反応装置を垂直に配置した。下部に、使用済みのクロミア/アルミナ触媒(SucChemie(独国)からのCatofin(登録商標))を8ml充填した。この第2の区域は高さが約70mmであり、この触媒床の上の残りの50mmは空のままであり、第1の区域と称する。第1の区域は500℃に加熱し、第2の区域は560℃に加熱した。室温の供給ガスを、52ml/分の流量および大気圧で第1の区域に供給した。生成物ガス流の組成をインラインGC測定により1時間に一度モニタし、その後、急冷し、形成された水を除去した。表1に、供給ガスの組成と生成物ガスの組成(32時間後)が与えられている。二酸化炭素の転化率は約36%であった。生成物中のメタンの量は時間が経つにつれ増加し、約1週間後に第1の区域においてコークスの堆積が見られたことに留意されたい。
比較実験Aを繰り返したが、第1の区域に石英粒子を充填し、両方の区域を600℃に加熱した。表1に提示された結果は、同様の転化率を示しており、またメタンの量が時間が経つにつれ増加し、コークスの形成が見られた。約1週間後に実験を停止し、第1の区域は、蓄積したコークス堆積物により実質的に遮断されたようであった。
この実験において、反応装置の区域を石英粒子で完全に充填し、それぞれ、450℃および650℃で加熱した。比較実験AおよびBにおけるように、同じ供給ガスを通過させ、ある程度のメタンの形成が観察され、両方の区域においてコークスが形成された。わずかな二酸化炭素のみが一酸化炭素に転化されたようであった。
ここで、反応装置の両方区域にクロミア/アルミナ触媒を完全に充填し、さらに、比較実験Bと同様に、実験を行った。表1に要約された結果は、著しく高い二酸化炭素の転化率(約52%)を示すのに対し、メタンは検出されなかった。生成物ガスの組成は、3週間の期間に亘り実質的に安定であり、コークス堆積物は観察されなかった。
第2の区域の温度を560℃(600℃の代わりに)にして、実施例1を繰り返した。わずかに低い二酸化炭素の転化率(約48%)が得られ、反応は、メタンもコークスも観察されずに、3週間に亘り安定に行われた。
