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。A CO_2-rich oil field gas can be used to produce a food-grade CO_2, 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.
