  6. 제1항에 있어서, 흡착대역에서 탈착대역까지의 온도변화는 약 250°F(121.1℃)인 것을 특징으로 하는 방법.
  7. 제1항에 있어서, 흡착대역에서 탈착대역까지의 압력변화는 약 10psia인 것을 특징으로 하는 방법.
  8. 제1항에 있어서, 흡착대역은 약 60psia인 것을 특징으로 하는 방법.
  9. 제1항에 있어서, 흡착온도는 약 950°F(510.0℃)인 것을 특징으로 하는 방법.
  10. 제1항에 있어서, 탈압력은 약 70psia인 것을 특징으로 하는 방법.
  11. 제1항에 있어서, 탈착온도는 약 1200°F(648.9℃)인 것을 특징으로 하는 방법.
