the effect of nio/coo ratio on the effective diffusion coefficient of methane gas in the pellet (nio)x- (coo)(1-x) nanoparticles

The effective diffusion coefficient (de) of ch4 into the pellets (nio)x-(co3o4)(1-x) (x=0, 02, 04, 06, 08, 1) binary mixtures nanoparticles(nps) were investigated using a thermogravimetric method in this method, the reduction reaction was carried out of nio and co3o4, and ch4 as metal precursors, and a reducing agent, respectively the reduction reaction of (nio)x-(co3o4)(1-x) (x = 0, 02, 04, 06, 08, 1) binary mixtures nps via 23 vol% of ch4 was experimentally investigated at constant reduction temperature (830 ºc) and under atmospheric pressure a mixture of ch4 and ar with a flowrate of 296 cm3/min in the reduction reaction was used in addition, the effective diffusion coefficient (de) of ch4 into the pellets were studied on (nio)04-(coo)06 samples with non-sintered and sintered modes
