  • Publication number: 20050203195
    Abstract: Novel methods of Fischer-Tropsch synthesis are described. It has been discovered that conducting the Fischer-Tropsch synthesis over a catalyst with a catalytically active surface layer of 35 microns or less results in a liquid hydrocarbon product with a high ratio of C5-C20:C20+. Descriptions of novel Fischer-Tropsch catalysts and reactors are also provided. Novel hydrocarbon compositions with a high ratio of C5-C20:C20+ are also described.

  • Patent number: 6422611
    Abstract: An expansion joint device (10) used for metal conduits comprises an inlet short tube (1), an outlet short tube (2), and a sleeve (3). Both the opposed inside ends of the two short tubes (1, 2) are in the inside of the sleeve (3) and form a compensating gap (6) between them. A bellows member (7), axially expansible with an external force applying on, is provided in the compensating gap (6) formed between the opposed inside ends of the two short tubes (1, 2). The two ends of the bellows member (7) are respectively connected with the inside ends of the two short tubes (1, 2) in sealed manner. At least one of the two ends of said sleeve (3) is free end with respect to the two short tubes (1, 2).

  • Publication number: 20020034626
    Abstract: The present invention is a mesoporous silica film having a low dielectric constant and method of making having the steps of combining a surfactant in a silica precursor solution, spin-coating a film from this solution mixture, forming a partially hydroxylated mesoporous film, and dehydroxylating the hydroxylated film to obtain the mesoporous film. It is advantageous that the small polyoxyethylene ether surfactants used in spin-coated films as described in the present invention will result in fine pores smaller on average than about 20 nm. The resulting mesoporous film has a dielectric constant less than 3, which is stable in moist air with a specific humidity. The present invention provides a method for superior control of film thickness and thickness uniformity over a coated wafer, and films with low dielectric constant.
