“…The regeneration columns in AGRU will release a high concentration of CO 2 that removed from the feed gas stream including water and some non-condensables to the atmosphere. The current increasing CO 2 in the atmosphere is believed to impact the environment as greenhouse gas emission affecting the global climate change [4].…”

There are many oil and gas fields in Indonesia which contain high CO2 that need to be treated. The Acid Gas Removal Unit (AGRU) is installed to remove the CO2. The AGRU will release the CO2 gas from the regeneration column. It still contains a high concentration of CO2 (higher than 80%). The accumulation of CO2 emission to the atmosphere will impact the environment. To promote environment-friendly technology, the process can be improved with conversion of CO2 into methanol. It will provide a relatively closed loop of the carbon cycle and as a renewable energy alternative. This study aims to provide packed bed reactor design which can be implemented in the small-scale methanol production plant utilizing high CO2 feed gas. The reactor temperature was varied from 200°C to 250°C and pressure were operated in the range of 40 Bar up to 75 Bar. These variations were used to analyze the effects of methanol production. The simulation results showed that peak methanol production rate was achieved at the temperature around 230°C. As the conclusion, the reactor showed better performance at the higher pressure and higher temperature although the reaction is exothermic including the recycling process can reduce the cost of hydrogen.

New hybrid materials based on the grafting of Pd(ii)-amino complexes on the graphitic surface of AC: preparation, structures and catalytic properties

2 S-F/Pd(II) hybrids on the hydrogenation of 1-octene in methanol as a catalytic test were evaluated. 100 % conversion to n-octane at T = 323.1 K and P = 15 bar, was obtained with both catalysts and most of Pd(II) was reduced to Pd(0) nanoparticles, which remained on the AC surface. Reusing of the catalysts in three additional cycles reveals that the catalyst bearing the F ligand with larger Pd-complexing ability showed no loss of activity (100 % conversion to n-octane) which is assigned to its larger structural stability. The catalyst with the weaker F ligand underwent progressive loss of activity (from 100 % to 79 % in four cycles), due to the constant aggregation of the Pd (0) nanoparticles. Milder conditions, T = 303.1 K and P =1.5 bar, prevent the aggregation of the Pd(0) nanoparticles in this catalyst allowing the retaining of high catalytic efficiency (100 % conversion) in four reaction cycles.
