Abstract
Systems and processes for adjusting hydrogen content of a synthesis gas are provided. At least a portion of carbon monoxide in a syngas can be converted to carbon dioxide to provide a shifted syngas and condensed water. The syngas can have a first hydrogen to carbon monoxide ratio and a first temperature, and the shifted syngas can have a second hydrogen to carbon monoxide ratio and a second temperature, both greater than the first. Heat from the shifted syngas can be at least partially transferred from the shifted syngas to the condensed water to at least partially vaporize the condensed water. The syngas can be at least partially saturated with the at least partially vaporized condensed water. A ratio of the water vapor to syngas can be about 1.0 or less.
