【摘要】 在500℃、空速5000h^-1及催化剂存在的条件下,可将CO₂油田气中2%～3%的烃降至10ppm以下,并采用脱硫、脱烃、脱水、冷冻及分馏等工艺过程可得到食品级CO₂。更多还原

【Abstract】 A CO₂-rich oil field gas can be used to produce a food-grade CO₂, under the conditions at 500℃, space velocity 5000 hr^-1 and by a catalytic process to reduce 2%-3% hydrocarbons contained to less than 10 ppm, through the process step such as desulfurization, hydrocarbon removing, dehydration, refrigeration and distillation.更多还原
