Abstract
Systems and methods are provided for performing hydrodeoxygenation of bio-derived feeds while maintaining the hydrodeoxygenation catalyst in a sulfided state. During hydrodeoxygenation, a hydrogen-containing stream is provided to the hydrodeoxygenation reactor as a hydrogen treat gas to provide hydrogen for the reaction. In some aspects, the hydrogen treat gas used for hydrodeoxygenation can be formed at least in part from hydrogen that has been used as a stripping gas for removing HS from a rich amine stream. In other aspects, HS can be stripped using water vapor, and a resulting overhead HS stream can be compressed prior to incorporation of the HS into a hydrogen-containing stream. The resulting hydrogen-containing stream can include sufficient HS to substantially maintain the catalyst in the hydrodeoxygenation stage in a sulfided state.
