Abstract:
As interest in cleaner and more sustainable transportation fuels continues to grow, diesel alternatives such as biodiesel and renewable diesel have become increasingly important. This project compares conventional petroleum diesel, biodiesel, and renewable diesel based on their feedstocks, production processes, fuel properties, engine compatibility, and environmental impacts. Conventional diesel is produced from crude oil, while biodiesel and renewable diesel are derived from renewable sources including vegetable oils, animal fats, and recycled cooking grease. Biodiesel is created through transesterification and is typically blended with petroleum diesel due to its lower energy content and poor cold-weather performance. In contrast, renewable diesel is produced through hydrotreating, which creates a fuel that is chemically similar to petroleum diesel and can be used in existing engines without modifications. Although renewable diesel is more expensive to produce, it offers several advantages, including improved cold-flow properties, lower emissions, and compatibility with current fuel infrastructure. Overall, both biofuels provide significant reductions in lifecycle greenhouse gas emissions compared to conventional diesel, but renewable diesel offers the closest performance to petroleum diesel and represents a promising option for reducing the environmental impact of diesel-powered transportation.
