Check the chart for more details. For example C6H5C2H5 O2 C6H5OH CO2 H2O will not be balanced but XC2H5 O2 XOH CO2 H2O will. Carbon dioxide equivalent CO 2 e or CO 2 eq or CO 2-e is calculated from GWPFor any gas it is the mass of CO 2 that. Initially the fluidized bed is filled with a mass of 0453 kg potassium carbonate as the bed material to adsorb CO 2 introduced from the fluidized bed bottom. Mole ratios are used as conversion factors between products and reactants in stoichiometry calculations.
