Patent number: 4179270Abstract: There is disclosed herein a clean burning, non-volatile device useful for the ignition of fires in combustible medium such as charcoal briquettes. The device comprises a core composed of wax and cellulosic particles (e.g. sawdust), together with an adjacent absorbant material to take up any oily exudate from the core. The core and absorbant material, with an optional lighter strip for conveying a flame to the core, are enclosed in a flammable, oil impervious container.

Patent number: 4125568Abstract: Impurities that are carbonyl-containing organic compounds (e.g., acetaldehyde) are removed from organic hydrocarbons produced in conventional production facilities. The process comprises contacting the hydrocarbon product (e.g., butadiene) with an aqueous "scrubbing solution," containing a water soluble reducing agent (e.g., NaHSO.sub.3) in slightly greater amount than is theoretically required for complete reaction with the carbonyl compounds, in an in-line mixing means and then passing the mixture to a phase separator to separate the layers. The resulting "scrubbed" hydrocarbon product is substantially purified (e.g., to as low as less than 2 ppm carbonyl compounds). An optional second mixer and scrubbing tower are provided as a back-up system in case of surge conditions or maintenance of the first system.Type: GrantFiled: June 29, 1977Date of Patent: November 14, 1978Assignee: Mobil Oil CorporationInventors: Walter A.

Patent number: 4098339Abstract: Natural gas of low heating value, high CO.sub.2 content, is converted to valuable products by the combination process of steam reforming the desulfurized gas, subjecting the effluent of the steam reformer to a water gas shift reaction and converting the resultant carbon dioxide, the unreacted carbon monoxide and hydrogen to liquid product useful as fuel, e.g. methanol. In a preferred embodiment, the gas phase separated from the liquid fuel products is processed to provide a gas sufficiently rich in carbon dioxide for use in tertiary recovery of petroleum from natural reservoirs which have produced the quantity of oil available by natural drive.Type: GrantFiled: October 13, 1976Date of Patent: July 4, 1978Assignee: Mobil Oil CorporationInventors: Paul B.

Patent number: 4093029Abstract: Natural gas having a high CO.sub.2 content and low heating value is converted to useful and valuable products by the extensive removal of CO.sub.2 followed by conversion of the residue to a liquid product useful as fuel (e.g. methanol) through a process combining steam reforming and conversion of the resultant reformer stream, which contains CO, CO.sub.2 and H.sub.2 to liquid products. The CO.sub.2 removed from the natural gas feed is used, in a preferred embodiment, in tertiary methods of recovery of petroleum from natural reservoirs in which primary and secondary methods are no longer viable.Type: GrantFiled: March 24, 1977Date of Patent: June 6, 1978Assignee: Mobil Oil CorporationInventors: Paul Burg Weisz, John Clarence Zahner

Patent number: 4049187Abstract: Thermoformed cups, having elements adapted to provide a stable handle, which are nestable in a small space, the handle including a tab extending radially from the brim of the cup and a hinged flange at each side of the tab. To form the handle the flanges are turned down and are retained by shoulders of a recess in the upper surface of the cup. Weight of liquid in the cup causes the flanges to bear against the side of the cup to afford stability in addition to that resulting from retention by said shoulders.Type: GrantFiled: February 25, 1976Date of Patent: September 20, 1977Assignee: Mobil Oil CorporationInventor: John Florian
