Abstract:
The invention relates to a process for producing terephthalic acid and for purifying the mother liquor resulting from said process. Useful compounds can be extracted from the mother liquor and the purified mother liquor can be returned for use in the process. Advantageously, certain parameters of the mother liquor purification method are selected such that the purification provides an economic benefit as compared with other purification methods.
Abstract:
The present invention relates to a novel method for compatibilizing, i.e. improving miscibility of, otherwise immiscible organic materials highly useful in the fibers industry, as well as the compatibilized product of the method. These compatibilized products are stable in the liquid phase at temperatures ranging from about 40° C. to about 200° C. The method involves use of a glycol derived from polymerization of alkylene oxide and tetrahydrofuran, the alkylene oxide having from 2 to 4 carbon atoms, i.e. poly(tetramethylene-co-alkyleneether) glycol, in the mixture.
Abstract:
A haptic switch can be used to control one or more display screens. In an example embodiment, the haptic switch takes the form of a flooring sample—such as a sample piece or swatch of a flooring material, for example, ceramic tile, wood, or carpet—that is affixed or otherwise mechanically coupled to an electronic sensor, such as a proximity sensor, a touch sensor, or a pressure sensor. The haptic switch is communicatively coupled to a machine, and the machine stores or is otherwise able to access a database that correlates the haptic switch or its included flooring sample to corresponding texture map data that depicts the flooring sample. The haptic switch is thus usable to select its corresponding texture map data and cause the machine to use the selected texture map data in generating video content and displaying the generated video content on one or more display screens.
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:
Nonnaturally occurring organisms exhibiting improved carbon utilization and methods for production and use of these nonnaturally occurring organisms in chemical production from carbon containing feedstocks are provided.
Abstract:
Disclosed is a process for co-manufacture of ACRN and HCN with improved HCN selectivity and reduced solids formation in a shared product recovery section.
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.
