Auger and Reaction Studies of Poisoning by Sulfur and Regeneration of Metal Synthesis Gas Catalysts. Progress Report: April 1, 1975--December 15, 1975

The objective is to determine the rate and mechanism of (1) sulfur poisoning and (2) of regeneration of metal catalysts used in synthesis gas conversion to hydrocarbon products. Auger electron spectroscopy (AES) is used for surface analysis, and in-situ reaction studies of deactivation and regeneration are combined with microreactor studies to quantify sulfur poisoning. An all-glass internal recirculation microreactor has been designed, fabricated, debugged and integrated into a metal-free feed… more

Auger and Reaction Studies of Poisoning by Sulfur and Regeneration of Metal Synthesis Gas Catalysts. Progress Report, December 8, 1975--December 8, 1976

CO methanantion rates have been measured in the all-glass internal recycle reactor developed for this work. The methanation rate over the cylinder Ni film catalyst at 400/sup 0/C is 3.9 sec/sup -1/ initially, and the catalyst undergoes deactivation to a value of 1.8 sec/sup -1/, comparable with a reported value of 2.5 sec/sup -1/. The activation energy for Ni film on alumina is 24 kcal/mole, that for Ni film on silica is 17.8 kcal/mole comparable to values for Ni on these supports. The kinetics… more
