For industrial scale production of ethane (C'Hd), it is produced by passing purified ethylene (C2H4) and hydrogen gas through abed of porous activated carbon, which serves as a catalyst: C2H4 + H2C2H6 Experimental data for the gas-phase catalytic reaction are shown in Table 2. The limiting step in the reaction is known to be irreversible, so that the overall reaction is irreversible.
