  • Fischer-Tropsch synthesis (FTS) was carried out in heat-exchanger typed reactor with cobalt metallic foam catalyst. Considering the heat and mass transfer limitations in the cobalt catalyst, a Co-foam catalyst with an inner metallic foam frame and an outer cobalt catalyst was developed. The Co-foam catalyst was highly selective toward liquid hydrocarbon production and the liquid hydrocarbon productivity at $203^{\circ}C$ reached to $52.5ml/(kg_{cat}{\cdot}h)$, which was higher than that obtained by the Co-pellet. Furthermore, the heat-exchanger typed reactor was developed to efficiently control the highly exothermic reaction heat. The reaction heat generated in the FTS reaction on the cobalt active site was easily transferred to reactor wall by the metallic foam in the catalyst and the transferred reaction heat was directly removed by the hot oil which circulated the wall side of the heat-exchanger typed reactor.

  • The heat exchanger using the catalytic combustion can be applied to petrochemical processes and to VOC incineration facilities. In this work, the experiment for a new fin typed catalytic heat exchanger was conducted. Catalysts for the heat exchanger were determined by testing their catalytic activities over LPG in a micro-reactor. Based on experimental results of the fin typed catalytic heat exchanger, a small scaled heat exchange system was made to test its feasibility as a reboiler used in petrochemical processes. The results showed that the catalytic heat exchanger could combust off-gases effectively and at the same time could recover completely heat produced by catalytic combustion.
