     At 190 under atmospheric pressure, mixtures of C2H4 and H2 with small amounts of CO gave with 3 different catalysts the following yields (vol. % C2H4, H2, CO in the initial gas, space velocity, length of run in hours, yield (ml. per m.3) of heavy oil, light oil, gas oil, and H2O): 52.6, 37.5, 5.7, 104.1, per l. catalyst per hr., 12.2 hr., 86.3, 199.1, 285.4, 7.0; 48.9, 36.9, 7.6, 78, 47.0, 77.4, 224.8, 96.3, 21.3; 47.9, 38.5, 6.5, 85, 69.5, 38.7, 162.3, 100.4, 36.7.  The composition of the outgoing gas (vol. %) in these 3 experiments was C2H4, H2, CO, and C2H6, respectively:  2.4, 35.7, 0.8, 42.9; 19.1, 20.0, 9.7, 38.8; 12.8, 18.3, 8.6, 53.0 (balance N2).  The yield of liquid condensate (gas oil included) attains 30-45 ml. per l. per hr.  C2H4 reacts to the extent of 77.7-98.5%, H2 to 62.3-96.9%; CO is consumed mainly (up to 94.9%) in the beginning of the run, less at later stages.  The fraction of the reacted C2H4 converted to C2H6 varies 27.6-56.6%.  At constant space velocity, 100 l. per l. catalyst per hr., with a gas mixture containing about 7% CO, the optimum temperature, in the 100-250 range, is 190-210.  By fractionation of the products from an equimolecular mixture of C2H4 and H2, containing 4-7% CO, the gas oil constitutes about 36% of all organic products in the condensate, and consists, in wt. % (not including CH4) of C2H4, 1.1, C2H6, 18.2; C2H6, 19.0; C3H8, 3.3; C4H8, 54; C4H10, 4.1; or in % of the organic matter in the condensate, respectively, 0.35, 6.1, 6.3, 1.1, 18.1, 1.4.  More than half of the gas oil, 54 wt. %, is the nonhydrogenated dimer of C2H4, namely C4H8; the hydrogenated dimer, C4H10, is 4.1% (with respect to the weight of the condensate, C4H8 is 18.1, C4H10, 1.4%).  The presence of a C3H8+C3H6 fraction (22.3% of the gas oil, 7.4% of the condensate), with a C3H8 : C3H6 ratio of 0.2 : 0.3, indicates condensation of CH2 radicals with C2H4.  Fractions C6 and C8 (trimers and tetramers of C2H4) constitute, respectively, 18.8% and 12.6% of the condensate (with the gas oil separated); the presence of the fractions C5, C7, and C9 constituting, respectively, 12%, 16.5%, and 8.5% of the gas oil-free condensate, indicates reaction with CH2 radicals.  Unsaturated compounds attain up to 70% of the condensate.  By Raman spectra of the hydrogenated catalyzate, the fractions b. 69-126.5 contain only the corresponding normal hydrocarbons, the fraction b. 66-68.5, beside C6H14, also contains about 15% 2-methylpentane and about 25% 3-methylpentane; the fraction b. 27-36 contains, beside C5H12, about 15% 2-methylbutane.
