20140072495 | METHOD AND APPARATUS FOR CATALYTIC AND THERMOCHEMICAL REACTIONS - The invention relates to a hybrid reverse flow catalytic apparatus having two reaction zones: a homogeneous reaction zone in porous ceramic and a heterogeneous reaction zone with catalyst, arranged in two different catalyst beds. A first catalytic bed located in a central region of the reactor is provided with a low activity catalyst and a second catalyst bed located in a peripheral region of the reactor is provided with a high activity catalyst. The provision of two catalyst beds containing different catalysts reduces the effect of radial temperature gradients in the reactor and improves the overall efficiency of the reactor. The invention also relates to method of performing catalytic and thermochemical reactions in said apparatus. | 03-13-2014 |
20120301834 | HIGH PRESSURE OXY-FIRED COMBUSTION SYSTEM - A combustion system, and method. A combustor oxy-fired at high pressure delivers flue gas at pressure to a condensing means, such as a condensing heat exchanger, to produce a high temperature condensate for delivering thermal energy to an industrial process system, particularly for power generation, including a Brayton cycle, a Rankine cycle, or a binary fluid cycle system such as a Kalina cycle, and in particular as a bottoming cycle for an organic Rankine cycle. The combustor can concurrently provide direct heat to a secondary system, including a Brayton cycle system, a Rankine cycle system, and a binary fluid cycle system such as a Kalina cycle, without requiring significant modifications to the secondary system. The system and method provide for efficient and advantageous use of the higher temperature condensate produced. | 11-29-2012 |

20120237882 | Flue Gas Recirculation Method and System for Combustion Systems - A method and system for improving high excess air combustion system efficiency, including induration furnaces, using a re-routing of flue gas within the system by gas recirculation. Flue gas is drawn from hot system zones including zones near the stack, for re-introduction into the process whereby the heat recovery partially replaces fuel input. At least one pre-combustion drying zone, at least one combustion zone, and at least a first cooling zone exist in these furnaces. At least one exhaust gas outlet is provided to each pre-combustion drying and combustion zone. At least part of the gaseous flow from each system zone exhaust outlet is selectively delivered to an overall system exhaust, the remaining flow being selectively delivered via recirculation to cooling zones. Recirculation flow is adjusted to meet required system temperatures and pressures. The method and system provide efficiency improvements, reducing fuel requirements and greenhouse gas emissions. | 09-20-2012 |
20120111188 | HOT SIEVING ELECTROSTATIC PRECIPITATOR - An electrostatic precipitator and a method of removal of particulates from gaseous flows. A plurality of screens, secured in sets within a central chamber in a housing, comprise at least one set of electrically chargeable first screens and at least one set of electrically grounded second screens. For each set of chargeable screens, all the screens of the set are provided with an identical electrical charge, either positive or negative, and the set is provided with a plurality of spikes directed at the oncoming gaseous flow. At least one screen cleaning means selectively acts on the screens of each set. The precipitator can comprise a plurality of central chambers in a single housing or separate housings, and the chambers can be selectively activated or deactivated. The precipitator provides improved particulate removal from gaseous flows, including hot flows having temperatures up to at least 1200° C. | 05-10-2012 |
20120034683 | PETROLEUM BIOCONVERSION OF ORGANIC ACIDS TO PREVENT REFINERY CORROSION - The present invention relates to the use of microorganisms (biocatalysts), or catalysts derived from these organisms (enzymes), to improve the quality of crude oil and bitumen as an attractive alternative to current upgrading methods. The invention identifies and characterizes the microorganism species, in particular, | 02-09-2012 |
20110140691 | NON-DESTRUCTIVE DETERMINATION OF MAGNETIC PERMEABILITY TENSOR IN MATERIALS OF ARBITRARY SHAPE - A method of non-destructive determination of a local magnetic permeability tensor of a material comprises testing by X-ray diffraction on a first surface to identify and measure any surface stress in the material; performing a calibration test using magnetostriction to identify any effect of any determined stress; subjecting the material to a magnetic field having a strength H and measuring a field of induction B on the surface at the selected location and repeating this step by using gradual increases of H until a saturated value is determined for B, to determine a distribution of magnetic domains at the selected location; repeating the determinations of saturated values for B at additional locations on each selected surface of the material; and using the saturated values and distribution of magnetic domains to derive the magnetic permeability tensor. The non-destructive method provides increased accuracy for stressed or unstressed materials of arbitrary shape. | 06-16-2011 |
20100319454 | METHOD AND SYSTEM FOR DETERMINING YOUNG'S MODULUS AND POISSON'S RATIO FOR A CRYSTALLINE MATERIAL - There is disclosed a method and system for determining Young's modulus and Poisson's ratio for an electrically conductive crystalline material. In general, one or more surface acoustic waves are generated in the crystalline material and a velocity of the surface acoustic waves is recorded. One or more applied strains in the crystalline material are also recorded using X-ray diffraction. The Young's modulus and Poisson's ratio can be determined from the recorded velocity(ies) and applied strain(s). | 12-23-2010 |
20100188285 | DECOUPLED CLOCK MODEL WITH AMBIGUITY DATUM FIXING - The present invention relates to a method of processing Global Positioning System (GPS) carrier phase and pseudorange information. Dual-frequency carrier phase and pseudorange measurements from GPS receivers are processed by specifying separate oscillator parameters for the carrier phase and pseudorange measurements. Carrier phase estimates of errors of the oscillator are arbitrarily biased with respect to the pseudorange estimates, and ambiguity parameters are constrained to be integer-valued. Isolating the ambiguities as integer valued parameters provides extra information that can be exploited to maximize the use of GPS and other Global Navigation Satellite Systems. | 07-29-2010 |
20100016641 | CONVERSION OF GLYCEROL TO NAPHTHA-RANGE OXYGENATES - The invention provides a method of converting glycerol to oxygenates (i.e. one or more oxygen-containing hydrocarbons) of lower boiling point than glycerol itself The method involves reaction of glycerol with an alcohol under reduced pressure at a reaction temperature in a range of 150 to 300° C. in the presence of an oxygenation (solid acid) catalyst. The reaction product contains volatile oxygenates that may be used as fuels or fuel additives. | 01-21-2010 |
