Summary
The unusual and potentially significant selectivity behaviors exhibited by iron- and, particularly, cobalt-graphite intercalates during CO hydrogenation warrant continued investigation, using a differential/integral flow-type reactor capable of operating at elevated reaction pressure, i.e., 0 to 300 psig. Such a system will enable further characterization of these catalysts to be made in at least three important, but heretofore unexamined, areas: this will permit the rapid acquisition of such important data as comparative turnover frequencies and apparent activation energies for CO conversion. The accuracy, convenience, and flexibility of the measurements will be greatly improved with a flow-type reaction system. Measurements of deactivation properties perforce require the use of a flow reactor and cannot be meaningfully made using a closed reaction system. Particular emphasis will be placed on establishing the effects of varying pretreatment conditions on activity/selectivity responses of the graphitic materials compared to their supported homologs. Additional information about catalyst coking properties and consequent mass balances will also be obtainable from such experiments. The most important information accessible by an elevated-pressure flow reactor are the comparative dependences of product selectivities on reaction pressure for both pairs of catalysts. In view of the already greater tendency of iron- and cobalt-graphite catalysts to produce longer average product molecules than their spported counterparts, even at one atmosphere pressure, it is of obvious importance to determine whether this behavior persists at higher reaction pressures. The situation for cobalt-graphite will be of particular interest because of its unusually constant selectivity properties over a 100/sup 0/C range of reaction temperatures.
