Fuel processing refers to the various methods and technologies used to convert raw fuels into usable energy sources. This includes processes such as refining crude oil into gasoline and diesel fuel, converting natural gas into electricity, and producing biofuels from renewable sources like plants and algae. Fuel processing can also involve the purification and treatment of fuels to remove impurities and improve their efficiency and environmental impact. This can include processes such as desulfurization to reduce emissions of sulfur compounds, carbon capture to mitigate greenhouse gas emissions, and catalytic cracking to improve the performance of fuels. Overall, fuel processing plays a critical role in the production, distribution, and utilization of energy sources, and is a key focus area for research and development in the energy industry.
