Activated carbon is used to remove sulfides, hydrogen sulfide, thiophenes, and other sulfur compounds from petroleum and natural gas. It can also absorb water and other impurities to purify the oil and gas fluids and improve their quality

Activated carbon can serve as catalyst support, increasing the catalyst's surface area and improving reaction conditions in petroleum catalysis and reforming reactions, thereby enhancing reaction efficiency.

In petroleum and natural gas production processes, activated carbon can be used for wastewater treatment in petrochemical refining enterprises to remove organic pollutants and oil, purifying the wastewater to meet environmental discharge standards.

In natural gas extraction and transportation processes, activated carbon can be used to reduce methane emissions, which helps mitigate greenhouse gas production and its impact on climate change.
