ABSTRACT:

The hydrogenation of carbon monoxide to produce low-molecular-weight olefins (C sub 2 -C sub 4 ) has been investigated over unsupported iron-manganese catalysts. It was found that a catalyst with approximately 2 parts of manganese per 100 parts of iron was effective in modifying the activity and selectivity of unsupported iron catalysts for the production of C sub 2 -C sub 4 olefinic hydrocarbons. The initial objective of this study was to investigate the influence of the catalyst loading and reactor operating modes on the activity and selectivity of iron-manganese catalysts for carbon monoxide hydrogenation. The following modes were studied: (1) conventional dense-bed reactor, (2) dense bed trickle flow reactor, (3) dense bed pseudo slurry reactor, (4) diluted bed reactor, (5) diluted bed trickle flow reactor, and (6) diluted bed pseudo slurry reactor. The standard operating conditions were as follows: reactor temperature 593K (220 exp 0 C), reactor inlet pressure 2.76 MPa (440 psig), reactant gas space velocity 1.0 cm exp 3 g exp -1 s exp -1 and a H sub 2 /CO ratio of 2. Mobil Number 1 base stock MCP-151 without additives and n-hexadecane were used as heat transfer media in the trickle flow and pseudo slurry reactor operations. A complete process variable investigation was conducted in the diluted bed reactor and in the diluted bed pseudo slurry reactor using n-hexadecane as the heat transfer liquid. The process variables investigated were reaction temperature, reactor pressure, H sub 2 /CO ratio and reactant gas space velocity. 98 refs., 77 figs., 9 tabs. (ERA citation 10:048318)
