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.

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.
