     Mixture of CO, H₂, and C₂H₄ passed over a catalyst under atmospheric pressure at 190°-200° undergo hydrocondensation, mainly into aliphatic hydrocarbons.  The following data give the composition of the gaseous mixture, space velocity in l. per l. catalyst per hr., duration in hours, yields (in mil. per m.³ of total gas passed) of heavy oil, light oil, total oil, H₂O; mean yield of total oil in ml. per l. catalyst per hr.: 1 CO : 2H₂ : 3C₂H₄, 93, 90, 130.8, 212.5, 343.3, 29.6, 30.2; 1 CO : 2H₂ : 1.5C₂H₄, 106, 71, 107.5, 88.1, 195.6, 19.4, 85.1.  On a particularly active catalyst, a mixture 1 CO : 2H₂ : 3C₂H₄ gave, at a space velocity of 114-135, in 49 hr., total oil 333-465 ml. per m.³ total gas passed, or 33-49 ml. oil per l. catalyst per hr., with a maximum of 465.2 ml. per m.³ or 49.2 ml. per ll. per hr., at a space velocity of 118.  The yield of H₂O was 55-96 ml. per m.³, and the volume ratio of light to heavy oil decreased during the operation from 1.42 to 0.85.  The balance of the C₂H₆ formed and of the amounts of each component spent in the reaction shows that C₂H₄ reacts to the extent of 80-93% and that only 15-22% of the C₂H₄ that reacts is spent on formation of C₂H₆; H₂ reacts to the extent of 87-99%, with only 20-33% of the reacting H₂ being spent on formation of C₂H₆.  Of the CO, 71.4% enters the reaction at its initial stage; at later stages, about 48-51% of the CO enters the reaction.  Formation of the liquid and solid products consumes, on the average, 2-3 vol. H₂ and 3-4.5 vol. C₂H₄ per vol. CO.  Preliminary study of the oily and aqueous products showed only a small amount of oxygenated compounds, mainly alcohols; among these, iso-PrOH was identified.  The oil is a mixture of saturated and unsaturated aliphatic hydrocarbons.
