The effect of 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 characterized by X-ray diffraction and temperature programm... https://www.sukrensi.com/
