<p>The present invention provides a process for controlling the ratio of hydrogen to carbon monoxide in feed streams (14, 18) to reactors (16, 22) that convert syngas to hydrocarbon liquids. The process includes primary syngas production process (12) for converting hydrocarbon gas to syngas comprising hydrogen and carbon monoxide. The process further includes introducing a hydrogen rich stream (68, 46), a carbon monoxide rich stream (70), or both produced by an auxiliary source (66, 44) to a feed stream (14, 18) being passed to a reactor (16, 22) for converting the syngas to hydrocarbon liquid, thereby adjusting the H2/CO ratio in the feed stream (14, 18). Examples of reactors (16, 22) that may be used to convert syngas to hydrocarbon liquids are FT reactors staged in series and oxygenate producing reactors staged in series.</p> |
