摘要:The present invention is directed to a process for the synthesis of 2,5-furandicarboxylic acid (FDCA) comprising the steps of: (1) oxidising an aqueous solution of 5 hydroxymethylfurfural (HMF) in the presence of molecular oxygen, of a heterogeneous catalyst comprising ruthenium and of a strong base at a temperature above 100° C., obtaining a reaction product in aqueous solution comprising a salt of FDCA acid; (2) separating said heterogeneous catalyst from said reaction product in aqueous solution, and (3) re-using said heterogeneous catalyst in the oxidation reaction in step (1).

摘要:Described herein are catalyst support materials for use in synthesizing ammonia (NH 3 ) from nitrogen gas (N 2 ) and hydrogen gas (H 2 ) and methods of making the same. The support material may comprise (MgO) x (BaO) y (Al 2 O 3 ) z and/or (MgO) x (SrO) y (Al 2 O 3 ) z , on which an ammonia synthesis catalyst such as ruthenium is dispersed. When the catalyst support material comprises (MgO) x (BaO) y (Al 2 O 3 ) z , x is from about 0.05 to about 0.7, y is from about 0.05 to about 0.6, and z is from about 0.3 to about 0.5. When the catalyst support material comprises (MgO) x (SrO) y (Al 2 O 3 ) z , x is from about 0.4 to about 0.7, y is from about 0.05 to about 0.5, and z is from about 0.05 to about 0.3.
