Direct Homogeneous Synthesis of Compounds with Two O Atoms and Long-Chain Hydrocarbons from CO and H: Co-Ru/N-methylpyrrolidone Catalyst.

The homogeneous acetic acid synthesis-type Ru-Co-Li/N-methylpyrrolidone catalyst for CO and H transformations has been studied at moderately high pressures. For 1CO:2H, low acetic acid selectivity has been observed, along with remarkable methyl acetate selectivity, the absence of aldehydes and ethyl acetate and sharp deviations from the Anderson-Schultz-Flory distribution for both alcaohols and long-chain hydrocarbons. For 1CO:1H and slightly elevated pressure, acetic acid selectivity slightly increased, notable ethyl acetate formation was detected, and both long-chain hydrocarbons and alcohols disappeared.

Cobalt-Containing Dispersion Catalysts for Three-Phase Fischer-Tropsch Synthesis.

Nanosized catalyst dispersions have significant potential for improving hydrocarbon production from carbon monoxide and hydrogen via Fischer-Tropsch synthesis, an essential alternative to the use of petroleum as a raw material. New dispersed cobalt catalysts and dispersed-phase cobalt-based catalysts with Pd, AlO, or ZrO additives for the Fischer-Tropsch synthesis were synthesized in the present work. A dispersed cobalt phase was prepared in a heavy paraffin medium using and approaches through thermal decomposition of a nitrate precursor at various temperatures.
