2010 Spring Meeting & 6th Global Congress on Process Safety
(134a) Processes to Produce Value Added Products From CO2
The possible ways to convert CO2 to valuable products are (1) catalytic conversion of CO2; (2) electro catalytic/electrochemical process; (3) photo catalytic/photochemical process; (4) enzymatic/biochemical process and (5) plasma processes. Hydrocarbon, hydrogen and oxygenates are mainly produced by the catalytic conversion of CO2 at the temperature and pressure of 250-1000 °C and 140-3500 psi, respectively. On the other hand, electrocatalytic/electrochemical process produces alcohol, aldehydes, ketones, other oxygenated, alkenes and alkanes at very low temperature (room ? 150 °C). CO2 is converted to hydrogen and hydrocarbons by photocatalytic/ photochemical process at the temperature and pressure of 5-400 °C and 485-1,470 psi, respectively. Bi-carbonate and alcohols are produced from CO2 at low temperatures and pressures using enzymatic/biochemical process. Furthermore, CO, syn gas, hydrocarbons are alcohols are the main product from the plasma process at low pressure and high temperature. Successful implementation of the above mentioned processes could be a possible solution to reduce the amount of CO2 emission into the atmosphere. Detail of these processes will be discussed at the conference.
