ABSTRACT:

A 15% iron boride on SiO sub 2 catalyst was prepared using an alcohol solution reduction with NaBH sub 4 . H sub 2 chemisorption measurements were performed for Fe-S-100 (3% Fe/SlO sub 2 ) and are in progress for the iron-boride-silica catalyst. Reduction of Co catalysts at 623 K rather than 723 K is being tested as a method to improve dispersion by decreasing the amount of Co-support interaction. An in depth study of non olefinic and nonparaffinic compound retention times on the 10% SP2100 chromotograph column has shown that the compounds elute in the following order for a specific carbon number: alkene < alkane < aldehyde < ketone < ester < alcohol < acid. Mass flow controllers have been installed in the reactor system and are fully operational. (ERA citation 06:013290)
