i was asked to design a reactor that convert carbon dioxide to methane in upgrading biogas process to biomethane using aspen plus

I have problem in inserting the data in aspen plus after i press run there is no changing in the outlet stream in the same time no error appear. i think the problem is unit problem but couldnot know exactly.

the reaction is happened in two steps first water gas shift reaction then co methanation

????????2 + ????2→    ???????? + ????2????               ΔH = -40.6 kJ/mol

3????2 + ???????? →    ????????4 + ????2????           ΔH 298 K = 206 kJ/mol

i already have the kinetics and rate of reaction based on  Langmuir-Hinshelwood-Hougen-Watson (LHHW) kinetics model

I get my information from this paper, tried to put screenshot from it but i couldnot
