  • Patent number: 6586480
    Abstract: Process and economic advantages are achieved by the integration of a Fischer Tropsch process for hydrocarbon liquids production as a retrofit in an installation for the production of ammonia fertilizer from fossil fuel derived syngas. Utilization of most of the CO and part of the H2 in the syngas stream during Fischer-Tropsch synthesis as the first step in the integrated process produces hydrocarbon products while the F-T effluent containing unreacted hydrogen gas at the necessary ratio of H2/N2 is used in the second step of ammonia synthesis. The overall product slate as appropriate for maximum economic performance of the installation is thus achieved.

  • Patent number: 6576214
    Abstract: A process for catalytically directly producing hydrogen peroxide (H2O2) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14×10−4 and 5.0×10−4 at reaction condition of 0-100° C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.

  • Patent number: 6534661
    Abstract: The invention discloses a dual-functional catalyst composition and an integrated process for production of olefin epoxides including propylene oxide by catalytic reaction of hydrogen peroxide from hydrogen and oxygen with olefin feeds such as propylene. The epoxides and hydrogen peroxide are preferably produced simultaneously in situ. The dual-functional catalyst comprises noble metal crystallites with dimensions on the nanometer scale (on the order of <1 nm to 10 nm), specially dispersed on titanium silicalite substrate particles. The dual functional catalyst catalyzes both the direct reaction of hydrogen and oxygen to generate hydrogen peroxide intermediate on the noble metal catalyst surface and the reaction of the hydrogen peroxide intermediate with the propylene feed to generate propylene oxide product.

  • Patent number: 6500969
    Abstract: A process for producing oxidized organic chemical products from various organic chemical feedstocks utilizing as oxidant hydrogen peroxide (H2O2) produced by noble metal nanocatalysis with high selectivity at low hydrogen concentration. The organic chemical oxidation process step can optionally be carried out in situ concurrent with the production of hydrogen peroxide or in a two stage process. In the two stage process, the hydrogen peroxide intermediate is directly produced by noble metal nanocatalysis from hydrogen and oxygen feeds plus a suitable solvent in a first catalytic reaction step. An organic chemical feedstock and the hydrogen peroxide intermediate and solvent solution are fed into a second catalytic reactor to produce an oxidized organic chemical product.

  • Patent number: 5113549
    Abstract: A paint roller pan detachable handle or lifter has been discovered that facilitates convenient and rapid movement of paint roller pans when they are filled or partially filled with paint. The configuration of the handle is such that the paint roller pan can be lifted and carried with one hand without bending over to pick up the pan, thereby reducing the risk of paint spills and speeding the application of paint. The novel handle contains features that engage the rim and bottom of the pan and releasably hold the pan. A rim engaging clamp that is slidably attached to an upright portion of the handle provides means for rapid detachment of the handle from the paint roller pan. In one embodiment of the novel handle of the invention the upper portion of the handle contains a means, such as an arcuate surface, for retaining a paint roller handle such that the paint roller and paint roller pan can be carried together.
