    摘要： A catalyst in a calcined state has a specific surface area of 20-50 m2/g of catalyst, and a specific surface area of nickel metal after reduction of the catalyst of 8 to 11 m2/g, wherein the average particle size of nickel metal is 3-8 nm, the dispersion of the particles is 10-16%, and the content of nickel is 5-15 wt. % based on the weight of calcined catalyst. A support has a specific surface area of 40-120 m2/g with a pore volume of the support of 0.2-0.4 cm3/g, wherein the support is selected from a mixture of zirconium oxide and cerium oxide or magnesium oxide, cerium oxide and the ballast being zirconium oxide. The catalyst further contains a promoter selected from the group consisting of palladium and ruthenium, in an amount of from 0.01 to 0.5 wt. %. The catalyst is prepared by co-precipitation with ammonium hydroxide from a solution containing nickel, cerium and zirconium precursors and distilled water or from a solution containing nickel, cerium, zirconium, and magnesium precursors and distilled water, and having a pH of 8.0-9.0. The process is carried out under agitation at a temperature of 40-45° C. for 1-2 hours, followed by filtration, drying at a temperature of 100-110° C. for 6-8 hours, and calcining at a temperature of 400-650° C. for 4-6 hours. The invention provides a high average conversion of natural/associated gas of at least 90% in an autothermal reforming reaction of natural or associated gas, and a high synthesis gas output of at least 7000 m3/m3cat·h.

    摘要： Example seismic sensors and methods relating thereto are disclosed. In an embodiment, the seismic sensor includes an outer housing and a proof mass disposed in the inner cavity of the outer housing. In addition, the seismic sensor includes a first biasing member positioned in the inner cavity between the proof mass and an outer housing upper end that is configured to flex in response to axial movement of the outer housing relative to the proof mass. Further, the seismic sensor includes a second biasing member positioned in the inner cavity between the first biasing member and the outer housing upper end. Still further, the seismic sensor includes a sensor element positioned in the inner cavity between the proof mass and an outer housing lower end that is configured to generate a potential in response to movement of the outer housing relative to the proof mass.

    摘要： The invention relates to gas analysis and to combustible gas and vapour analyzers based on a thermocatalytic operating principle. The subject of the invention is a sensor the sensitive elements of which are manufactured by planar techniques that can be easily automated. The main distinguishing feature is that a working sensitive element and a reference sensitive element are colocated in a single micron-sized structural component (a microchip) on a common substrate made of porous anodic aluminium oxide. The design of the sensitive elements provides for film-wise heat transfer from heated parts of the working and reference sensitive elements. Measuring microheaters which heat the working and reference sensitive elements up to working temperatures and provide for differentially measuring an output signal in a measuring bridge circuit are spaced apart at opposite sides of the anodic aluminium oxide substrate and are disposed on arms projecting beyond the common substrate configuration. The sensitive elements are disposed in a reaction chamber having restricted diffusion access via a calibrated orifice, and the diameter of regular pores in the microchip substrate is increased to sizes that provide for a predominantly molecular diffusion mode in the pores (100 nm or more).

    摘要： A seismic sensor includes an outer housing having a central axis, an upper end, a lower end, and an inner cavity. In addition, the seismic sensor includes a proof mass moveably disposed in the inner cavity of the outer housing. The outer housing is configured to move axially relative to the proof mass. Further, the seismic sensor includes a first biasing member disposed in the inner cavity and axially positioned between the proof mass and one of the ends of the outer housing. The first biasing member is configured to flex in response to axial movement of the outer housing relative to the proof mass. The first biasing member comprises a disc including a plurality of circumferentially-spaced slots extending axially therethrough. Still further, the seismic sensor includes a sensor element disposed in the inner cavity and axially positioned between the first biasing member and one of the ends of the outer housing. The sensor element includes a piezoelectric material configured to deflect and generate a potential in response to the axial movement of the outer housing relative to the proof mass and the flexing of the first biasing member.

    摘要： The material for proppant and method for producing the same relate to the chemistry of high-molecular weight compounds, and more particularly, to polymer materials with high requirements for physical and mechanical properties, for instance, for the production of proppants, i.e., propping granules, used in the oil and gas production by a method of hydraulic fracturing of formation. The technical result achieved by implementation of the present invention is an increase in thermal strength of the proppant material providing for a compressive strength of at least 150 MPa at a temperature of not less than 100° C. The method consists in the following. A mixture of oligocyclopentadienes is obtained by heating dicyclopentadiene (DCPD) to a temperature of 150-220° C. and holding at this temperature for 15-360 minutes. The oligomerization of dicyclopentadiene occurs. The mixture of oligomers is cooled down to 20-50° C., and polymer stabilizers, radical initiators, methacrylates and a catalyst are sequentially added thereto. The resultant polymer matrix is heated up to a temperature of 50-340° C. and is held at this temperature for 1-360 minutes, and thereafter is cooled down to room temperature. A metathesis polymerization (MP) and radical polymerization (RP) cross-linkage of the mixture of oligocyclopentadienes with methacrylic esters occurs.
