Description
(1)式に示すように、この改質反応により、1モルのジメチルエーテルと1モルの二酸化炭素とから、3モルの水素と3モルの一酸化炭素とが生成し、分子数が3倍に増大して体積膨張が発生することが分かる。また、ジメチルエーテル1モルの発熱量は1328kJであり、転化して生成される一酸化炭素及び水素の発熱量の合計値が1575kJであるので、この改質反応により、発熱量は約18%増加することになる。
2 脱硫塔
3 改質反応器
Claims (3)
- 製鉄所の高炉から排出される高炉ガスを触媒の存在下でジメチルエーテルと反応させて、ジメチルエーテル及び高炉ガス中の二酸化炭素を一酸化炭素と水素とに改質し、これにより、改質後の高炉ガス中の二酸化炭素を削減すると同時に、改質後の高炉ガス中の一酸化炭素及び水素の含有量を増加させることを特徴とする、高炉ガスの改質方法。
- 改質後の高炉ガス中の二酸化炭素の濃度が、高炉から排出された時点での高炉ガス中の二酸化炭素濃度の10%以下となるように、高炉ガスとジメチルエーテルとを反応させることを特徴とする、請求項1に記載の高炉ガスの改質方法。
- 請求項1または請求項2に記載の高炉ガスの改質方法によって得られた改質後の高炉ガスを、燃料ガスとして利用することを特徴とする、高炉ガスの利用方法。
