Literature Abstracts

Mixture of approximate equal parts of CO and H₂ with a trace of O₂, when passed at a space velocity of 1,500-2,000 over a Ni-Pd catalyst supported on Al or pumice stone, produced 1-3% of C₂H₄ at temperatures in the neighborhood of 100°; the catalyst lost 0.5% of its efficiency in 30 hr. Other catalysts in order of decreasing activity were Ni-Cu-Pd, Fe-Ni-Pd, Ni-Pt, Cu-Co-Fe, Cu-Pd, Cu-Co-Ni, C-Pd, Ni-Cu, Cu-Co. While saturated hydrocarbons were not specially sought, Ni and Ni-Pd catalysts yielded from 20-25% CH₄ at temperatures in the neighborhood of 250°. The catalysts showed little decrease in activity after several days’ use.
