In addition, the catalyst mass was varied to control the propane conversion so that selectivity and yield could be compared at a constant propane conversion. At the same propane conversion, propene selectivity increased as the partial pressure of oxygen decreased. Thus, propene yields can be ...
The effect of a partial pressure of nitrogen of 50 atmospheres (5065 kilopascals) on the hydrogen evolution reaction of nitrogenase has been investigated. ... F Simpson,R Burris - 《Science》 被引量: 601发表: 1984年 Initial stages of propane activation over Zn/MFI catalyst studied by in situ...
Partial liquid ventilation (PLV) improves oxygenation in several models of lung injury. However, PLV has only been compared with conventional gas ventilation (GV) with low PEEP. Both PLV and GV can markedly improve oxygenation when PEEP is set above the lower corner pressure (Plc) on the inspi...
The catalytic activity of Ni/ α Al 2O 3 for partial oxidation of methane to synthesis gas has been studied. It is found that the catalyst of 10% Ni content was the best one for partial oxidation of methane under the conditions of 600~900℃ reaction temperature, 0 05 MPa pressure, a ...
Heterogeneously catalyzed partial direct oxidation of propane and/or isobutane to (meth)acrylic acid target product(s) involves: (a) feeding a starting reaction gas mixture comprising propane and/or isobutane, molecular oxygen and at least one inert diluent gas having an inlet pressure (P1) to a...
The shell gasification (POX) process is a flexible process for generating synthesis gas, principally hydrogen and carbon monoxide, for the ultimate production of high-purity high pressure hydrogen, ammonia, methanol, fuel gas, town gas, or reducing gas by reaction of gaseous or liquid hydrocarbon ...
1) ozone partial pressure 臭氧分压 OPP2) bisOPP-A 双OPP-A 1. 2,2-bis(3-phenyl-4-hydroxyphenyl)propane(bisOPP-A) is a new type of monomer used mainly in the synthesis of high molecular polymers,such as polycarbonate,epoxy resin,polyester,etc,and it is also used for polymer ...
of about 1700° F. to 2400° F., and a pressure in the range of about 1 to 250 atmospheres, and substantially comprising H2, CO, CO2; at least one gas from the group consisting of H2O, CH4, N2, Ar, H2S, COS; and entrained free-carbon soot; so that the atomic ratio of free ...
Prebreakdown phenomena and formation processes of low pressure glow discharges in N[sub 2], O[sub 2], and N[sub 2]/O[sub 2] mixtures The prebreakdown phenomena and the resulting transient processes from the prebreakdown phenomena to the glow discharge in low-pressure N 2 , O 2 gases, ...
A pressure switch and gauge cabinet 152 is also included on the auxiliary bedplate. Cabinet 152 contains the pressure switches, gauges, regulators and other miscellaneous elements needed for gas turbine operation. Although not specifically shown, it should be understood that plant 100 also incorporates...
