Abstract: A method for producing oil and/or gas comprising injecting a miscible enhanced oil recovery formulation into fractures, karsts, and/or vugs of a formation for a first time period from a first well; producing oil and/or gas from the fractures, karsts, and/or vugs from a second well for the first time period; injecting a miscible enhanced oil recovery formulation into the fractures, karsts, and/or vugs for a second time period from the second well; and producing oil and/or gas from the fractures, karsts, and/or vugs from the first well for the second time period.

Abstract: The invention provides an auxiliary power unit (APU) and process for electricity generation in combination with an internal combustion engine in which the APU includes a solid oxide fuel cell (SOFC) having an inlet for fuel, an inlet for air and/or engine exhaust gas, and an outlet for off-gas; and a catalytic partial oxidation reformer (CPOx) having an outlet which is connected to the inlet for fuel of the SOFC and an inlet for reactants, wherein the inlet for reactants is connected to an outlet for engine exhaust gas of the internal combustion engine through an evaporator having an inlet for fuel and an inlet for engine exhaust gas and an outlet which is connected to the inlet of the CPOx.

Abstract: A reformer such as a CPO (18) receives a mix of fuel, moisture and oxygen from a mixing region (21) having an igniter (26, 66), which may include an inert ceramic foam (19), the fuel being provided by an atomizing nozzle (22), thereby avoiding the need for a vaporizer before use. The oxygen and moisture may comprise engine exhaust (11, 12). Fuel from a vehicle fuel tank (9), may be gasoline, diesel fuel, kerosene, jet fuel, or JP-8. The atomizing nozzle may be a gas-assist nozzle (22a), receiving the assisting gas from (a) engine exhaust (10), (b) a turbocharger (33), (c) an air pump (50) or (d) a steam generator (57). The oxygen and moisture may comprise moisturized air, which may be achieved by an ejector (41) which ingests water from a tank (43) in response to the flow of air from a pump (50) through a conduit (47). The air may be regeneratively heated (48) with the CPO exhaust. The igniter may be a glow plug (26) or a heater wire (66) coated with catalyst.

Abstract: A fuel processing system (FPS) (120, 220, 320) provides a hydrogen-rich reformate having a reduced level of CO (34, 234, 62), as for use in a fuel cell power plant (120). The FPS includes, in combination, a reformer (30, 230) for converting hydrocarbon feedstock (22) to reformate and a multistage hybrid WGS reactor (150, 250, 350) for converting CO with H2O in the reformate to H2 and CO2 to reduce the CO in the reformate. The multistage hybrid WGS reactor (150, 250, 350) has one stage (154, 254, 352) of active noble metal catalyst (174, 274, 374), typically platinum and/or rhenium, and an other stage (152, 252, 354) of Cu-based WGS catalyst (172, 272, 372), e.g. Cu/ZnO, whereby the collective volume of the one and the other stages is relatively small, being less than about ½ that of prior WGS reactors. The Cu-based WGS catalyst may be modified to reduce self-heat. Protection from sulfur in the reformate is also provided. The multistage hybrid WGS reactor (150, 250, 350) may further include an O2 guard.

Abstract: A process for the selective oxidation of hydrogen sulphide in a hydrogen sulphide containing feed gas to elemental sulphur, wherein the hydrogen sulphide containing feed gas (3), an inert liquid medium (5), and a molecular-oxygen containing gas (4) are supplied to a reaction zone (1) comprising at least one catalytic zone (2) comprising an oxidation catalyst to form elemental sulphur and a gaseous stream depleted in hydrogen sulphide (8), in which process the oxidation catalyst of each catalytic zone (2) is contacted with hydrogen sulphide and/or molecular-oxygen in the presence of inert liquid medium at a temperature in the range of from 120 to 160° C., under such conditions that the elemental sulphur formed is essentially in liquid form and is removed from the reaction zone with the inert liquid medium.
