  • Patent number: 8350073
    Abstract: The present invention provides methods for the synthesis of catalysts and precursors thereof. Methods of the invention may comprise combining a catalyst precursor and at least one ligand to generate a catalytically active species, often under mild conditions and in high yields. In some cases, a wide variety of catalysts may be synthesized from a single catalyst precursor. Methods of the invention may also include the preparation of catalysts which, under reaction conditions known in the art, may have been difficult or impossible to prepare and/or isolate due to, for example, steric crowding at the metal center. The present invention also provides catalyst compositions, and precursors thereof, which may be useful in various chemical reactions including olefin metathesis. In some cases, methods of the invention may reduce the number of synthetic and purification steps required to produce catalysts and/or other reaction products, as well as reducing time, cost, and waste production.

  • Patent number: 8329455
    Abstract: This invention relates generally to systems and methods for digestion of solid waste that simplify solids handling. In certain embodiments, anaerobic methane extraction takes place for a period of time (e.g., from 1 to 4 weeks), after which an aerobic composting process begins in the same chamber. The organic waste remains in place and oxygen (e.g., in air) is forced into the chamber for an additional period of time (e.g., from 2 to 4 weeks). At the conclusion of the aerobic phase, the process yields a rough compost product that is stable and pathogen free. The rough compost can be further processed and blended to create high value engineered soils.
