摘要： Methods and apparatus for providing the heat required to maintain the desired temperature for catalyst regeneration. The catalyst is heated by contacting a reactant gas mixture with the catalyst in order to initiate an exothermic reaction and, once the desired temperature is achieved, exposing the catalyst to a regenerating gas. The temperature may also be maintained by heating the reactant gas mixture prior to contacting the catalyst and/or adding a liquid, which may be heated, to the catalyst. For heating a Fischer-Tropsch catalyst for regeneration, the reactant gas preferably contains less than 12 mole percent carbon monoxide and more preferably contains between 1 and 4 mole percent carbon monoxide.

摘要： Methods and apparatus for separating liquid products and catalyst fines from a slurry used in a Fischer-Tropsch reactor. A settling system continuously or intermittently removes catalyst fines from the slurry and is coupled with catalyst-liquid separation system that separates liquid products from the slurry. The preferred separation system produces a sub-particle rich stream and a catalyst-lean stream that are removed from the system. The systems of the present invention act to reduce the concentration of catalyst fines in the reactor, thereby increasing the effectiveness of a catalyst-liquid separation system.

摘要翻译： 提供保持催化剂再生所需温度所需热量的方法和装置。 通过使反应气体混合物与催化剂接触来加热催化剂，以引发放热反应，并且一旦达到所需温度，将催化剂暴露于再生气体。 温度也可以通过在催化剂接触之前加热反应气体混合物和/或加入可以加热的催化剂的液体来维持。 为了加热费 - 托催化剂用于再生，反应气体优选含有少于12摩尔％的一氧化碳，更优选含有1至4摩尔％的一氧化碳。
