    摘要: A multistage catalytic partial oxidation (CPO) process for oxidizing a hydrocarbon feedstream comprising C1-C4 hydrocarbons, with an oxygen-containing feedstream to produce a product comprising CO and H2, also known as synthesis gas or syngas. The process employs a CPO catalyst, and controlled process features, including: (A) the total oxygen requirement for the process is introduced incrementally, in more than one reaction stage, using an oxygen-containing feedstream at more than one feed point in the process, each stage including a catalyst; (B) the oxygen-containing feedstream, hydrocarbon feedstream and, in reaction stages after the first of said multiple stages, the intermediate product produced in the prior stage, are mixed for a period of time, after they are brought into contact with one another, of less than about 1 millisecond to form a substantially uniform mixture, wherein the mixture is then contacted with the catalyst; (C) the oxygen-containing feedstream and the hydrocarbon feedstream are preheated prior to entry into the first stage, to a temperature of from about 450° C. to less than about 1,000° C.; and (D) the mixture temperature of the product in each stage following the first stage is from greater than about 600° C. to less than about 1,000° C. Preferably, the process comprises less than or equal to about five stages, the first stage preheat temperature recited in step (C) is greater than about 550° C. and the mixture temperature of the product in each stage following the first stage is at least 700° C.

    摘要: The present invention is an optically enhanced solar cell having a detached reflector. The optically enhanced solar cell includes a semiconductor material bounded on each side by transparent electrical contacts and an optional antireflection coating with the surface of at least one of these layers being textured. Light is reflected in the cell by a reflector which is detached (i.e., spaced) from the enhanced cell using a layer of dielectric material.

    摘要: Hollow shell laser fusion targets, such as glass microballoons, are filled with gases of the type which do not permeate through the wall of the balloon. A hole is laser-drilled in the balloon, a plug is placed over the hole and gas is introduced into the balloon through the loosely plugged hole. Thereafter the plug is melted to form a seal over the hole, entrapping the gas within the target. The plug is, for example, a polymer such as highly crystalline polystyrene, or glass.

    摘要: In order to assay the tritium fuel content in laser fusion targets and/or to measure the pressurization of laser fusion targets of the type which use deuterium and tritium (DT) gas mixtures, without destroying the targets, the flux of beta particles which emerges from the target is measured with the aid of a gas flow proportional counter. The count rates are related to the tritium content and the pressurization. The tritium content in terms of the mass of the tritium in the target can be derived from the counting rate.
