摘要： A process for production of dialkyl succinate from bio-succinic acid feedstock where solid bio-succinic acid is fed to a reactor to react with alkanol by autocatalytic esterification. Products from the reactor including unreacted succinic acid, mono alkyl ester, dialkyl ester, alkanol, water and impurities are sent to a reaction distillation column for esterification of succinic acid and further esterification of mono alkyl ester with upflowing alkanol. The bottoms products from the reaction distillation column including residual succinic acid, mono alkyl ester, dialkyl ester, impurities and alkanol are sent to a bottoms stream separation zone where di-alkyl ester is separated from alkanol, succinic acid, mono alkyl ester and impurities. The tops products from the reaction distillation column including alkanol, water and organic components are sent to a top stream distillation zone where alkanol is separated from water and organic components. The organic components are recycled to the reaction zone column.

摘要： A process for the production of dialkyl succinate from a bio-succinic acid feedstock commencing by feeding bio-succinic acid to a reaction distillation column to enable esterification of the succinic acid. The feedstock is passed co-currently with upflowing alkanol such that an esterification reaction occurs. An overhead vapor stream is removed from the reaction distillation column comprising di-ester, alkanol, water of esterification and organic components. The vapor stream is sent to an alkanol separation column where alkanol is separated from the water of esterification and organic components. A side draw is removed from the alkanol separation column comprising partially immiscible organic and aqueous phases. The side draw is passed to a phase separation apparatus where the partially immiscible organic and aqueous phases are separated. The organic phase is passed to a column where the dialkyl succinate is recovered from residual water and other organic components.

摘要： The present disclosure provides systems and methods for regenerating a hydrogenation catalyst with reduced water consumption and/or shortened overall regeneration time. The method can include contacting a fouled hydrogenation catalyst with a first flushing medium comprising water and a gaseous phase comprising oxygen and optionally a second flushing medium comprising water and a gaseous phase comprising at least 90% nitrogen by volume. The method can further include treating the effluents of the flushing mediums by ion exchange resin to remove impurities in the effluents.

摘要： The present disclosure provides methods for producing a regenerated hydrogenation catalyst from a fouled hydrogenation catalyst having a total surface area and at least one associated impurity. The method can include maintaining contact between the fouled hydrogenation catalyst and a flushing medium that comprises water, oxygen, and an inert or diluent gas at a regeneration temperature and a regeneration pressure sufficient to remove at least a portion of the at least one impurity from the hydrogenation catalyst to produce the regenerated hydrogenation catalyst, where the regenerated hydrogenation catalyst is characterized as retaining at least 70% of the activity of the hydrogenation catalyst.
