    Abstract: An improved isobutanol synthesis process is provided which proceeds through the formation of mixed alcohols from syngas. The two-step process avoids the slowest α-carbon addition reaction in the conventional one-step, direct isobutanol synthesis process. Once ethanol and propanol are produced in the first reaction zone, they can react with methanol and/or syngas in a second reaction zone to produce isobutanol through the fast β-carbon addition reaction in the presence of catalysts, resulting on significantly improved isobutanol productivity.

    Abstract: Processes and apparatus for making xylenes and phenol are described. Phenol and alkyl phenols are separated from coal derived liquid. The phenol is separated from the alkyl phenols. The alkyl phenols can be reacted with aromatics such as benzene and toluene to make xylenes. The xylenes and other aromatics are then separated from the phenol and alkyl phenols. Para-xylene is separated and recovered using a xylene separation process, and meta-xylene and ortho-xylene are optionally converted to para-xylene through an isomerization reaction.

    Abstract: A low pressure re-absorber is integrated with a sulfur-rich solvent flash drum or a sulfur-rich solvent stripping column in a solvent acid gas removal process that provides for sufficient sulfur concentration for the downstream sulfur recovery unit. In another aspect of the invention, carbon dioxide containing or carbon dioxide rich gas streams that are at a lower temperature relative to a lean solvent stream are used to cool those lean solvent streams and then optionally to cool other process streams, to save energy consumption.

    Abstract: Embodiments of a process for discharging amine byproducts formed in an amine-based solvent are provided. The process comprises the steps of contacting the amine-based solvent with flue gas comprising carbon dioxide, oxygen, nitrogen, NOx, SOx, or mixtures thereof to form a carbon dioxide-laden amine-based solvent that contains the amine byproducts. Carbon dioxide is separated from the carbon dioxide-laden amine-based solvent to form a carbon dioxide-depleted amine-based solvent. The amine byproducts from the carbon dioxide-depleted amine-based solvent are fed to an algae source.
