Renewable diesel Production: A Review

open access: yesPetroleum and Chemical Industry International, 2023
Biodiesel is considered an alternative to petroleum diesel as it is more environmentally friendly, cleaner, decreases greenhouse gas emissions, non toxic and biodegradagable. Although, low energy density, relatively high cost of production and poor cold flow are some of its demerits. Some of these problems can be reduced by renewable diesel. The demand
