Abstract: This invention utilizes a novel method and set of operating conditions to efficiently and economically process a potentially very fouling hydrocarbon feedstock. A multi-stage catalytic process for the upgrading of coal pyrolysis oils is developed. Coal Pyrolysis Oils are highly aromatic, olefinic, unstable, contain objectionable sulfur, nitrogen, and oxygen contaminants, and may contain coal solids which will plug fixed-bed reactors. The pyrolysis oil is fed with hydrogen to a multi-stage ebullated-bed hydrotreater and hydrocracker containing a hydrogenation or hydrocracking catalyst to first stabilize the feed at low temperature and is then fed to downstream reactor(s) at higher temperatures to further treat and hydrocrack the pyrolysis oils to a more valuable syncrude or to finished distillate products. The relatively high heat of reaction is used to provide the energy necessary to increase the temperature of the subsequent stage thus eliminating the need for additional external heat input. A refined heavy oil product stream is recycled to the fresh feed to minimize feedstock fouling of heat exchangers and feed heaters.

Abstract: A process for two-stage catalytic co-processing of coal and heavy petroleum hydrocarbon liquid fractions to produce increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a petroleum residuum and optionally with a process-derived hydrocarbon liquid solvent and fed into a first stage catalytic reaction zone operated at relatively mild conditions which promote controlled rate liquefaction of the coal while simultaneously hydrogenating the petroleum and hydrocarbon recycle oils at conditions favoring hydrogenation reactions. The first stage reactor is maintained at 650.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure and 10-100 lb/hr/ft.sup.3 space velocity for the total coal and oil feed. From the first stage reaction zone, the partially hydrogenated effluent material is passed directly to the close-coupled second stage catalytic reaction zone maintained at more severe conditions of 750.degree.-900.degree. F. temperature for further catalytic; and hydrogenation and hydroconversion reactions. By this process, the blended coal and petroleum feed materials are successively catalytically hydrogenated and hydroconverted at the selected conditions, which results in significantly increased yields of desirable low-boiling hydrocarbon liquid products and minimal production of undesirable residuum and unconverted coal and hydrocarbon gases, while catalyst life is substantially increased.

Abstract: The invention described herein relates to a novel process that eliminates the need for post combustion CO2 capture from fired heaters (at atmospheric pressure and in dilute phase) in a petroleum refinery to achieve environmental targets by capturing CO2 in a centralized facility and providing fuel gas low in carbon to the fired heaters. It combines the pre-combustion capture of carbon dioxide with production of a hydrogen fuel source within a refinery to drastically reduce the carbon dioxide emissions of the plant. The hydrogen fuel is utilized for the process fired heaters and the fuel quality (carbon content) can be set to meet the refinery's emissions objectives. Moreover, the carbon dioxide captured can be sequestered and/or utilized for enhanced oil recovery (EOR).

Abstract: A multi-stage catalytic process for hydrogenation and liquefaction of coal using ebullated-bed catalytic reactors to produce low-boiling hydrocarbon liquid products, in which used catalyst is removed from a lower temperature first stage reactor operating at temperature not exceeding about 800.degree. F. and cascaded forward to a higher temperature second stage reactor for further use therein. Reaction conditions in the first stage reactor are preferably 700.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure, and a coal feed rate of 10-90 lb coal/hr per ft.sup.3 catalyst settled volume in the reactor. Useful higher temperature or second stage reaction conditions are 750.degree.-850.degree. F. temperature, and 1000-4000 psig hydrogen partial pressure. The used catalyst withdrawn from the lower temperature of first stage reactor has a catalyst age of 300-3000 lb coal proceses/lb fresh catalyst, and is transferred forward to the higher temperature second stage reactor for further use to catalyst age of 1000-6000 lb coal processed per lb fresh catalyst. If desired, a higher temperature third catalytic reactor can be provided and used catalyst from the second stage reactor cascaded forward into the third reactor for further use therein. Useful catalysts include metal oxides of cobalt, iron, molybdenum, nickel, tin, or tungsten deposited on a base of alumina, magnesia, silica, or titania, with cobalt moly and nickel moly on alumina catalyst being preferred. This process advantageously requires a smaller quantity of fresh catalyst per ton of coal processed to produce the low-boiling hydrocarbon liquid products.

Abstract: A broadly tunable single-mode infrared laser source based on semiconductor lasers. The laser source has two parts: an array of closely-spaced DFB QCLs (or other semiconductor lasers) and a controller that can switch each of the individual lasers in the array on and off, set current for each of the lasers and, and control the temperature of the lasers in the array. The device can be used in portable broadband sensors to simultaneously detect a large number of compounds including chemical and biological agents. A microelectronic controller is combined with an array of individually-addressed DFB QCLs with slightly different DFB grating periods fabricated on the same broadband (or multiple wavelengths) QCL material. This allows building a compact source providing narrow-line broadly-tunable coherent radiation in the Infrared or Terahertz spectral range (as well as in the Ultraviolet and Visible spectral ranges, using semiconductor lasers with different active region design). The performance (tuning range, line width, power level) is comparable to that of external grating tunable semiconductor lasers, but the proposed design is much smaller and much easier to manufacture.

Abstract: A mask programmable integrated circuit includes a read only memory (ROM), a random access memory (RAM), and a controller. The controller couples to the ROM and RAM. The controller senses a reset condition and, in response, directs a clear of the RAM or a preload of contents of the ROM to the RAM. The preload can be performed after a successful self-test of the RAM is achieved. The RAM has a variable word length and depth size and can be configured to operate in one of many modes. The integrated circuit further includes a first and a second multiplexer (MUX). The first MUX is interposed between the RAM and the ROM, and selectively couples either the ROM data or the built-in self-test (BIST) data to the first MUX output. The second MUX is interposed between the first MUX and the RAM, and selectively couples either the output of the first MUX or a (synchronous or asynchronous) data input to the RAM. With the preload feature, the invention can emulate a ROM, a preloaded RAM, or look-up table logic functions as well as conventional RAM. Further, BIST allows for testing of the RAM without the needs for external support.

Abstract: A process for two-stage catalytic hydrogenation and liquefaction of coal to produce increased yields of low-boiling hydrocarbon liquid and gas products. In the process, the particulate coal is slurried with a process-derived liquid solvent and fed at temperature below about 650.degree. F. into a first stage catalytic reaction zone operated at conditions which promote controlled rate liquefaction of the coal, while simultaneously hydrogenating the hydrocarbon recycle oils at conditions favoring hydrogenation reactions. The first stage reactor is maintained at 650.degree.-800.degree. F. temperature, 1000-4000 psig hydrogen partial pressure, and 10-60 lb coal/hr/ft.sup.3 reactor space velocity. The partially hydrogenated material from the first stage reaction zone is passed directly to the close-coupled second stage catalytic reaction zone maintained at a temperature at least about 25.degree. F. higher than for the first stage reactor and within a range of 750.degree.-875.degree. F. temperature for further hydrogenation and thermal hydroconversion reactions. By this process, the coal feed is successively catalytically hydrogenated and hydroconverted at selected conditions, which results in significantly increased yields of desirable low-boiling hydrocarbon liquid products and minimal production of undesirable residuum and unconverted coal and hydrocarbon gases, with use of less energy to obtain the low molecular weight products, while catalyst life is substantially increased.
