CO2 rich natural gas sources

CO2 -rich natural gas sources are popular in Vietnam, with their CO2 contents in the range of 10 - 60 mol%. Based on various CO2 contents of natural gas sources, a certain number of technologies are recommended for their wise uses. If the gas contains less than 10 mol% of CO2 , it can be used where urea production. In the case where its CO2 content is up to 25 mol%, methanol and dimethyl ether (DME) production could be considered. Gas with CO2 content of up to 50 mol% could be a good feedstock for carbon nanotube (CNT) production.

The rapid increase in emissions of major greenhouse gases such as CO2 and CH4 in the last decade has seriously affected the climate change and the living environment in the world in general and in Vietnam in particular. In addition, the demand for effective use of CO2 - rich natural gas has promoted studies to find new, highly active and stable catalysts for the methane reforming process. NiO has proven to be the most suitable catalyst for industrial application of the reforming process.
