摘要：
A hydrocarbon synthesis (HCS) process wherein a Fisher-Tropsch reactor is operated to maximize the selectivity to 371°C+ boiling fraction while minimizing the production of less valuable products such as light gases (C1-C4), naphtha and diesel fractions. Inventive modes of operation to offset the effects of catalyst deactivation and maximize selectivity to 371°C+ boiling fraction are utilized including (a) reducing gas inlet velocity to maintain an optimal CO conversion level, (b) introducing additional active catalyst until a maximum loading is reached, and (c) increasing reactor temperature until productivity reaches a predetermined cut-off level.
