Patent Abstracts

Hydrocarbons with 3 or more C atoms are produced from CO and H₂, the ratio of CO : H₂ being at least 3 H₂ : 1 CO, preferably 4-6 H₂ : 1 CO. The synthesis gas therefore is made from a mixture of CH₄, H₂O, and CO₂ which contains 20-60% CO₂ and 20-60% H₂O. According to an example, the synthesis gas is made from a mixture of 40% CH₄, 40% H₂O, and 20% CO₂ and in the presence of Ni at 700º-870º. A synthesis gas, which contains 64% H₂, 16% CO, and 16% CO₂, yields at 343º and 28 atm. C₃ and C₄ hydrocarbons beside higher molecular hydrocarbons and water-soluble alcohols.
