Key equations of PBR simulation of three-reaction global model.

PBR balances species j	Net rates r_j	Mole fractions y_j	Partial pressures
$d F_{j} / d W = r_{j}$ $At W = 0,$	$r_{C H_{4}} = - r_{1} - r_{3}$	$y_{j} = \frac{F_{j}}{\sum_{j} F_{j}}$	$p_{j} = y_{j} P$
$F_{j o} = value$	$r_{C O_{2}} = - r_{1} - r_{2}$	Total molar rate includes inert gas	P = total pressure
	$r_{CO} = 2 r_{1} + r_{2} + r_{3}$
	$r_{H_{2}} = 2 r_{1} - r_{3} + 3 r_{3}$
	$r_{H_{2} O} = r_{2} - r_{3}$
