EFFECT OF THE NICKEL PRECURSOR ON DEACTIVATION OF NI/SIO2 CATALYSTS DURING THERMAL CATALYTIC DECOMPOSITION OF METHANE AT 823 K

Effect of the nickel precursor on deactivation of Ni/SiO2 catalysts during thermal catalytic decomposition of methane at 823 K

The effect of mel axolotl the nickel precursor [Ni(NO3)2 or Ni(O2C2H3)2] on deactivation of Ni/SiO2 catalysts for thermo catalytic decomposition (TCD) of methane at 823 K has been investigated.TCD of methane was studied by the thermogravimetric method, monitoring the mass change of the catalyst due to carbon deposition.The samples were characterize

An Ultra-Wideband Circularly Polarized Asymmetric- $S$ Antenna With Enhanced Bandwidth and Beamwidth Performance

chicago cubs earrings This paper introduces an ultra-wideband circularly polarized (CP) asymmetric-S antenna with wide axial ratio beamwidth (ARBW) for C-band applications.The proposed antenna is realized by bending a linearly polarized dipole into asymmetric-S shape with variable trace width, which achieves CP radiation.Unlike the reported symmetr
