What is the time scale for coal solubilization and methanation reaction in the biogenic coal bed methanation?

The reaction mechanism is coal - solubilized coal - fragmented coal - benzoate - acetate - products (CH4 and CO2) based on the acetoclastic pathway. I wish to know the relative speed for these...

How do sodium salicylate and CTAB improve the stability of the coal particle slurries in water, particularly above the critical micelle conc?

The concentration of surfactants is well above the critical micelle concentration in water. Does the adsorption of surfactant ions on the surface of the coal particles contribute in forming stable...

How is the kinetic rate constant of propagation (kp) expected to affect the quantity of polymer produced per grams of catalyst used?

I am calculating polymer produced as, (M_0 (λ_1+μ_1 ))/(Catalyst in moles * Mol wt.of catalyst) , where M0 is the monomer molecular weight, λ_1 is concentration of the first moment of living...

I am observing an overshoot in G' at high strains in addition to weak overshoot in G" at lower strains. Can anyone suggest why this behaviour occurs?

The system consists of TiO2 nanoparticles (~21 nm) in an anisotropic liquid crystal medium. The particle concentration is above 10 wt%. The overshoot in G' occurs at around 30% strain amplitude....
