Abstract: A single pass analyzer includes multiple infrared sensors, a catalytic converter, a scrubber and a thermal conductivity cell all coupled in series to provide a single pass (i.e., one sample) analyzer which allows for fast analysis, allows for the speciation of hydrogen samples, requires no purging between different sample types, utilizes a single carrier gas, and eliminates molecular sieves and Shutze converters. The resultant analyzer provides improved quicker results with less plumbing (i.e., gas conduits and valving) in a single instrument.

Abstract: An analyzer compensates for gas flow perturbations by providing a makeup flow of carrier gas to maintain the pressure and/or flow rate of analyte and inert gas through a detector constant such that a accurate determination of a low concentration of an analyte in the presence of a high concentration of a second analyte can be accurately determined. In one embodiment, a carrier gas is introduced through a valve responsive to the detected pressure in the gas flow stream between a scrubber and a subsequent detector for maintaining the pressure constant during an analysis. In another embodiment of the invention, a flow transducer is positioned in the gas flow path between the scrubber and detector and coupled to a flow control valve coupled to introduce carrier gas as a function of detected gas flow such that the flow rate of gas into the detector is maintained constant.

Abstract: A process for the catalytic cracking in a fluidized bed where the feed stock is fully and previously vaporized before made to contact the cracking catalyst which has its origin in the regenerator. The pre-vaporization of the feed dispenses with the heat exchange with the catalyst in order to vaporize the feed. Thus, coke deposits on the catalyst surface are reduced, the yield of the gasoline unit is improved and the unit may operate under very low contact times (<0.5 seconds). Modes for adjusting the heat balance of the unit as a function of the increase in the feed temperature without harm to the catalyst circulation are also presented.

Abstract: An analytical furnace includes a pair of generally vertically extending coaxially mounted spaced furnace tubes mounted to a support. The inner tube is made of a material which does not react with the specimen during pyrolysis to produce intereferring byproducts. An analytical sample crucible is supported above the support by a carbonaceous material which in the preferred embodiment comprises a combination of a carbon-felt packing material resting on the support and granular carbon black on which the crucible is placed. The material is selected to position the crucible in the hot zone of the furnace which includes a heater for heating an analytical sample for pyrolysis. The analytical furnace further includes a lance tube extending over and in coaxial alignment with the inner and outer furnace tubes for directing a sample and a carrier gas into the open mouth of the cup-shaped crucible.

Abstract: A vertical resistive combustion furnace having a vertically oriented combustion zone in which first and second coaxially aligned tubes depend. The first tube is open at one end and closed at the other. The second tube is open at one end and partially closed at the other end and is mounted within and spaced from the first tube with the space between the coaxial tubes defining a passage for combustion products produced from a sample of material to be analyzed, disposed in said second tube. The combustion products pass upwardly in the channel through the combustion zone of the furnace so that the combustion products are hot when they exit the furnace for analysis.
