蒸气比

模拟结果表明，最佳氧沥青比约在0.78～0.80之间，相应的每公斤沥青有效气（CO＋H＿2）产率约为2.5m￣3（标准状态）；而蒸气沥青比则以0.40左右为宜。

The simulation re-sults showed that the optimum oxygen-pitch ratio is about 0.78 ~ 0.80 and the optimum steam-pitch ratio is about 0 40.Related to it , the effective gases ( CO + H_2 ) yield of per-kilo-gram pitch is about 2 . 5m ￣ 3 .
