  • Patent number: 10722814
    Abstract: Continuous extraction units (CEUs) are constructed that allow switching of extraction chambers (ECs) that contain extractable material (EM) and extract solution. Extraction chambers can be removable and replaceable, where the CEU has a fluid flow portion and a liquid transfer portion. Quick-connect valves allow exchange of ECs in the CEU while under flow without solvent loss. Alternatively, the CEU employs pairs of ECs where a first EC at equilibrium partitioning of an extract solution drains to an expansion chamber (EXC) with an expansion valve (EV) and a heat transfer tube situated proximal to or shared with a solvent condenser (SC) to form of a double phase change heat exchanger (HE). Solvent from the SC fills a paired EC containing EM. A second pair of ECs has a first EC with EM and solvent establishing equilibrium and a second EC that is emptied of spent EM, filled with fresh EM, and readied to receive solvent.

  • Patent number: 10710949
    Abstract: Copper-containing, multimetallic catalysts with either a zirconia or carbon support are described which have improved utility for the hydrogenolysis of a glycerol or glycerol-containing feedstock to provide a biobased 1,2-propanediol product. specially, improved carbon-supported examples of such catalysts are described for this reaction as well as for other processes wherein hydrogen is used, with methods for maintaining the activity of these catalysts. Related treatment methods in the preparation of these improved catalysts enable the use of carbons with a desired mechanical strength but which previously lacked activity, for example, for the conversion of a glycerol or glycerol-containing feed to produce 1,2-propanediol, so that copper-containing, multi-metallic catalysts may be employed for making a biobased propylene glycol using carbon supports that previously would have not been suitable.
