AI Article Synopsis
- The greenhouse effect caused by carbon dioxide (CO2) is a critical global issue, prompting research into converting CO2 to methyl alcohol (CH3OH) using catalytic methods.
- A honeycomb-typed monolith was utilized as a catalyst support, which underwent both thermal and acid treatment to enhance its surface properties.
- Experiments indicated that while higher temperatures improved CO2 conversion in the hydrogenation process, they reduced selectivity for CH3OH, with optimal results achieved at around 250 degrees Celsius and 20 atm pressure.
Article Abstract
The greenhouse effect of carbon dioxide (CO2) has been recognized as one of the most serious problems in the world. Conversion of CO2 to methyl alcohol (CH3OH) was studied using catalytic chemical methods. Honeycomb-typed monolith used as catalyst support was 400 cell/inch2. Pretreatment of the monolith surface was carried out by thermal treatment and acid treatment. Monolith-supported nanosized CuO-ZnO catalysts were prepared by wash-coat method. The prepared catalysts were characterized by using SEM, TEM, and XRD. The catalytic activity for CO2 hydrogenation to CH3OH was investigated using a flow-type reactor with varying reaction temperature, reaction pressure and contact time. Conversion of CO2 was increased with increasing reaction temperature, but selectivity to CH3OH was decreased. Optimum reaction temperature was about 250 degrees C under 20 atm. Because of the reverse water gas shift reaction.
