Methods, systems and devices that utilize a mobile offshore drilling unit (MODU) with other integrated equipment, hereinafter a mobile offshore production unit (MOPU) or a traditional floating production unit (FPU) to produce oil and natural gas from an oil and gas containing subsea geological formation are described. When the MOPU / FPU consumes all produced natural gas in one or more processes onsite to produce products selected from power, liquid petroleum products, hydrogen gas, solid carbon, and combinations thereof, then the production unit is transformed into a Modular MOPU™. Some produced natural gas is used to generate electricity for normal facility operations and additional natural gas consumed to generate electricity for various 4th-phase processes or used as feedstock for the production of value added products in processing equipment such as pyrolysis units, and / or gas-to-liquids units. Maximizing consumption of produced natural gas onsite, optimizes oil production without flaring, and without any export pipelines.

This liquid petroleum gas production reactor comprises a housing part accommodating a Cu-Zn-based catalyst and a zeolite catalyst supporting a noble metal, wherein the proportion (wt1 / (wt1+wt2)) of the weight of the Cu-Zn-based catalyst to the total weight of the weight (wt1) of the Cu-Zn-based catalyst and the weight (wt2) of the zeolite catalyst in an upstream region of the housing part is different from the proportion (wb1 / (wb1+wb2)) of the weight of the Cu-Zn-based catalyst to the total weight of the weight (wb1) of the Cu-Zn-based catalyst and the weight (wb2) of the zeolite catalyst in a downstream region of the housing part.

The invention discloses a micro-emulsion-loaded hydrogel for cleaning smoked murals and a preparation method and application thereof, and belongs to the technical field of cultural relic preservation, the method comprises the following steps: mixing a polyoxyethylene ether nonionic surfactant, an anionic surfactant, saturated monohydric alcohol and liquid petroleum hydrocarbon, dissolving in water, and uniformly stirring at room temperature to obtain a micro-emulsion; the preparation method comprises the following steps: dissolving polyvinyl alcohol and polyacrylic acid in dimethyl sulfoxide, heating in a water bath, and gelatinizing to obtain a PVA-PAA hydrogel precursor; and putting the PVA-PAA hydrogel precursor into the micro-emulsion, and reacting at room temperature to obtain the micro-emulsion loaded hydrogel for cleaning the smoked mural. The microemulsion is stably fixed in a PVA-PAA gel network, so that the controllable release and localization effects of the cleaning agent are realized, and the permeation out-of-control of the traditional liquid cleaning agent is avoided. The cleaning agent has the advantages of simple preparation process, good mechanical properties and water retention, mild and efficient removal of smoked deposition, higher safety and protectiveness to a mural pigment layer and a substrate, and improvement of the cleaning efficiency and the operation stability.

Disclosed are fuel additives and methods for making and using the same. A fuel additive can ethyl cellulose. A mass of ethyl cellulose in powder form can be mixed with or into a volume of a petrochemical, such as gasoline, in liquid form. The ethyl cellulose powder may at least partially dissolve in the liquid petrochemical. Heat may be applied to improve dissolution of the ethyl cellulose in the liquid petrochemical. The ethyl cellulose / gasoline fuel mixture produced therefrom can be combusted in a combustion engine, such as a small combustion engine. Combustion testing shows that the ethyl cellulose / gasoline fuel mixture exhibits greater than about 150% increase in fuel efficiency relative to gasoline alone. Other additives and stabilizers can be added to stabilize the mixture.
