Abstract: The present invention relates to heterogeneous catalysts and methods of making and using the same. In various embodiments, the present invention provides a method of making a hydrogenation catalyst including particulate nickel metal (Ni(0)). The method includes calcining first nickel(II)-containing particles in an atmosphere including oxidizing constituents to generate second nickel(II)-containing particles. The method also includes reducing the second nickel(II)-containing particles in a reducing atmosphere while rotating or turning the second nickel(II)-containing particles at about 275° C. to about 360° C. for a time sufficient to generate the particulate nickel metal (Ni(0)), wherein the particulate nickel metal (Ni(0)) is free flowing.

Abstract: A method and system for trans-loading solid particulates from a hopper to a storage container, by clamping a trough (110) to a discharge gate of the hopper, the trough having an open top, sides, and a bottom, a vacuum pipe (140) extending into the trough, and at least one aerator (150) located on the trough, to which is provided an aerating gas. The method further comprises at least partially evacuating the storage container to cause at least a partial vacuum therein and drawing a vacuum through a conveyor hose connected to the trough.

Abstract: Embodiments of the present invention relate to methods for the biosynthesis of di- or trifunctional C7 alkanes in the presence of isolated enzymes or in the presence of a recombinant host cell expressing those enzymes. The di- or trifunctional C7 alkanes are useful as intermediates in the production of nylon-7, nylon-7,x, nylon-x,7, and polyesters.
