2. Exhaust from a process is contaminated with 600 ppm of benzene. The exhaust is passed through two parallel absorption beds filled with activated carbon at a rate of 1600 cubic meters per minute at 33C and 1 atm. Only one absorption bed is used at a time while the other is regenerated, and each is run for 3 hours before it is regenerated.

rWGS reaction CO2 H2 CO HO It is expected that the global CO2 emission will reach 40 Gtyear by 2040. Carbon dioxide (CO2) utilization using a heterogeneous catalyst has been extensively studied with the goal of mitigating the effects of global warming and its emissions. The CO2 hydrogenation reaction (i.e., reverse water gas shift (rWGS),
