  • Patent number: 7967954
    Abstract: A process for the conversion of hydrocarbons that are solid or have a high boiling temperature and may be laden with metals, sulfur or sediments, into liquids (gasolines, gas oil, fuels) with the help of a jet of gas properly superheated between 600 and 800° C. The process comprises preheating a feed 5 in a heater 8 to a temperature below the selected temperature of a reactor 10. This feed is injected by injectors 4 into the empty reactor 10 (i.e., without catalyst.) The feed is treated with a jet of gas or superheated steam from superheater 2 to activate the feed. The activated products in the feed are allowed to stabilize at the selected temperature and at a selected pressure in the reactor and are then run through a series of extractors 13 to separate heavy and light hydrocarbons and to demetallize the feed. Useful products appearing in the form of water/hydrocarbon emulsions are generally demulsified in emulsion breaker 16 to form water laden with different impurities.

  • Patent number: 7964153
    Abstract: In an upflow reactor for reacting heavy hydrocarbons with hydrogen gas in a liquefied catalyst slurry, that mixture is recirculated down through a downcomer having an upper degassing section which includes a frusto-conical upper surface. The mixture is caused to flow along that surface in a downward helical path, such that heavier components are centrifugally urged outwardly, and lighter components, e.g., gas, migrate inwardly. The gas bubbles can thus coalesce such that small bubbles become bigger bubbles having a greater tendency to rise out of the downcomer. Baffles placed on the upper surface can maximize the residence time of the mixture in the degassing section.

    Abstract: Methods and apparatus for facilitating the synthesis of compounds in a nonflow-through device are presented. Application of the nonflow-through methods and microfluidic devices to the synthesis of radiolabeled compounds is described. These methods and apparatus enable the introduction of a pressurized gas through a tangential slit into a vortex reactor of the nonflow-through device, while one or more liquids are delivered to the reaction chamber through the same or different inlet ports. The introduction of the pressurized gas produces a cyclonic motion of the mixture within the reactor. Such a mechanism may be used to facilitate the evaporation of various liquids within the reactor at lower temperatures, thus reducing the production of unwanted byproducts that are associated with the use of high temperatures. In addition, thorough mixing of various liquids may be effected rapidly while allowing chemical reactions to take place efficiently within the vortex reactor.

  • Patent number: 7448603
    Abstract: A catalytic hydrocracking reactor vessel includes enhanced components for the conversion of a hydrogen gas and fossil fuel feedstream to light liquid hydrocarbons. The reactor vessel comprises one or more of a reactor cup riser with a helical cyclonic separator conduit for separating a liquid and vapor product stream to provide an essentially vapor-free liquid recycle stream; a grid plate bubble cap with wall housing having serrated edges for producing small hydrogen bubbles of increased total surface area of bubbles at lower pressure drop; a feedstream inlet pipe sparger containing rows of downward directed slots for even distribution of the feedstream across the cross-sectional area of the reactor and providing free drain of solid particles from the sparger; and optionally a liquid recycle inlet distributor containing vertically curved plates for creating a whirling motion in the liquid recycle stream for better mixing with the feedstream with minimal solids settling.

  • Patent number: 6977002
    Abstract: A reforming catalyst is composed of a plurality of catalyst layers arranged in series, and when started from a low temperature, preheated air is supplied in parallel to a point upstream of each catalyst layer, thereby the catalyst in each layer is self-heated simultaneously so that the catalyst is heated. After the catalyst is heated, feed of air is temporarily stopped, and supply of fuel gas is started. Next, air is supplied while controlling its flow rate so that temperatures in the catalyst do not exceed the temperature that the catalyst can withstand. Thus, no other special equipment is needed, and the catalyst can be started quickly (cold start). The catalyst can be made compact enough to install it in a electric vehicle.

  • Patent number: 6896851
    Abstract: The wet-gas desulfurizing apparatus according to this invention removes the oxides of sulfur, such as SO2, from combustion exhaust gas by scrubbing the combustion exhaust with an absorption liquid which contains an alkali. It includes: 1) a branch pipe to circulate the absorption liquid which is inserted into a collection tank, of which the end discharges the absorption liquid into the collection tank, and the branch pipe having an internal diameter of D; and 2) an air-blowing pipe in inject air into the branch pipe, of which the end is inserted at an insertion point located between 3 D and 10 D from the discharge end of the branch pipe. The end of the air-blowing pipe is inserted into the branch pipe, and has an appearance of a semicircular trough facing downstream toward the collection tank.

  • Patent number: 6893484
    Abstract: Provided herein is an apparatus for scrubbing either acidic or alkaline impurities from gas streams, wherein the gas streams to be scrubbed exist at a pressure which is only slightly higher than ambient pressure. An apparatus according to a preferred form of the invention exists substantially in the shape of a rectangular or cubic solid, having an inlet pipe which is directed to an inner chamber having a wall portion which functions as a manifold, including a plurality of gas conduction tubes in fluid contact with the inner chamber, and into which tubes the gas to be scrubbed enters. The gas to be scrubbed passes through holes in the walls of the gas conduction tubes and contacts a liquid absorbent substance present in the interior confines of the apparatus, which liquid is capable of reacting with one or more impurities in the gas stream, thus eliminating the impurities from the gas stream. The gas stream so treated emerges from the apparatus through a gas outlet provision.

  • Patent number: 6878856
    Abstract: A bioremediation system converts a waste stream, at least part of which is a fluid containing energetics, to carbon dioxide (CO2), water, and environmentally benign end products. It uses gas-enhanced sequencing-batch-reactors (SBRs), treating the waste stream in three SBRs seriatim. The first SBR uses a nitrogen purge, the second a hydrogen gas supplement, and the third an oxygen gas or forced air supplement. Each reactor may be supplemented with additives to optimize conditions such as pH, dissolved oxygen, and nutrient level. The system may be implemented under manual control, semi-automated, or fully automated, as needed. A waste stream of consideration is the pink water resultant from munitions fabrication and handling.

  • Publication number: 20040247518
    Abstract: An efficient process to produce calcium thiosulfate (CaS2O3) from lime, sulfur and oxygen is described. By selecting appropriate process conditions such as mole ratios of lime to sulfur, temperature and pressure of the reaction process and the oxidation conditions, including rate and duration, the concentration of byproducts in the resulting suspension can be reduced to about 2% by weight or less. The solid particulate dispersion in the suspension tends to form a slimy solid suspension that is hard to filter if not treated properly. The suspension then can be acidified and treated with a flocculent. This agglomerates the solids into a floc that filters with ease. The resulting calcium thiosulfate is a clear liquid with concentrations achievable up to 29%.
