An object of the present invention is to provide a comprehensive utilization adjusting method and apparatus of the alkali chlorine method and the Fischer-Tropsch synthesis. The method includes 1) a Fischer-Tropsch synthesis gasification feedstock is gasified, the steps of the main composition to obtain a crude synthesis gas is H2, CO and CO2, 2) conventional industrial alkali chlorine method electrolysis of a saturated NaCl solution using, NaOH solution, obtaining a Cl2 and H2, 3) with NaOH solution and H2 obtained by alkali chlorine method, to remove CO2 in the crude synthesis gas purification the resulting synthesis gas, by adjusting the carbon hydrogen molar ratio in the purified synthesis gas, purifying synthesis gas comprises a step to satisfy the requirements of the feed gas of the Fischer-Tropsch synthesis. The apparatus includes a gasifier, alkali chlorine method electrolytic cell, a gas cleaning device and Fischer-Tropsch synthesis reactor. Combination alkali chlorine method and Fischer-Tropsch synthesis method organically, by adjusting the composition of the purified synthesis gas with hydrogen gas generated in the alkali chlorine method, to reduce the processing amount of water gas shift step, the work procedure simplicity. .FIELD 1
