Zusammenfassung:abstract a process (10) to produce fischer-tropsch products includes feeding feed synthesis gas (30) with a substantially constant target feed synthesis gas h2/co ratio to a fischer-tropsch synthesis stage (16). a portion of the feed synthesis gas (30) is converted to fischer-tropsch products in the fischer-tropsch synthesis stage (16). the fischer-tropsch products (20) from the fischer-tropsch synthesis stage (16) are withdrawn. a fischer-tropsch synthesis stage tail gas (26) which includes unconverted h2 and co is obtained. the operating conditions of the fischer-tropsch synthesis stage (16) are manipulated to achieve a substantially constant target tail gas h2/co ratio, with the target tail gas h2/co ratio being substantially different from the target feed synthesis gas h2/co ratio. tradução do resumo resumo patente de invenção: "síntese de fischer - tropsch" um processo (10) para produzir produtos de fischer - tropsch inclui alimentação de gás de síntese de alimentação (30) com uma razão de h2/co de gás de síntese de alimentação alvo substancialmente constante para um estágio de síntese de fischer - tropsch (16). uma porção do gás de síntese de alimentação (30) é convertida a produtos fischer - tropsch no estágio de síntese fischer - tropsch (16). os produtos fischer - tropsch (20) do estágio de síntese fischer - tropsch (16) são retirados. um gás de cauda de estágio de síntese de fischer - tropsch (26) que inclui h2 e co não-convertidos é obtido. as condições de operações do estágio de síntese de fischer - tropsch (16) são manipuladas para obter uma razão de h2/co de gás de cauda alvo substancialmente constante, com a razão de h2/co de gás de cauda alvo sendo substancialmente diferente da razão de h2/co de gás de síntese de alimentação alvo. A process (10) to produce Fischer-Tropsch products includes feeding feed synthesis gas (30) with a substantially constant target feed synthesis gas H2/CO ratio to a Fischer-Tropsch synthesis stage (16). A portion of the feed synthesis gas (30) is converted to Fischer-Tropsch products in the Fischer-Tropsch synthesis stage (16). The Fischer-Tropsch products (20) from the Fischer-Tropsch synthesis stage (16) are withdrawn. A Fischer-Tropsch synthesis stage tail gas (26) which includes unconverted H2 and CO is obtained. The operating conditions of the Fischer-Tropsch synthesis stage (16) are manipulated to achieve a substantially constant target tail gas H2/CO ratio, with the target tail gas H2/CO ratio being substan
