Worldwide consumption of energy produced from fossil fuels is forecasted to grow. This trend leads to both environmental pollution and the depletion of fossil fuel resources. Green diesel is a suitable candidate to substitute petroleum based-diesel due to its plentiful raw materials, non-polluting production process, and cost-effectiveness. Green diesel production is seen as simple, efficient, and relatively clean process. Deoxygenation (DO) is crowned as the best available technology to produce green diesel from palm fatty acid distillate (a side product of palm oil production) and other oils using heterogeneous catalysts such as zeolites. The capability of catalysts can be improved by optimizing operating parameters, treating and modifying catalysts and with the use of nano-sized catalytic materials. These activities contribute to stronger and more active Bronsted-Lewis acid-base sites and enlarged crystallite sizes, which improve the DO efficiency, selectivity, and reusability, to produce high-grade green diesel with less oxygen content.

预计全球对化石燃料产生的能源的消费量将增长。这种趋势导致环境污染和化石燃料资源的枯竭。绿色柴油由于其原料丰富、生产过程无污染、成本效益好，是替代石油基柴油的合适候选者。绿色柴油生产被视为简单、高效且相对清洁的过程。脱氧 (DO) 被认为是使用非均相催化剂（如沸石）从棕榈脂肪酸馏出物（棕榈油生产的副产品）和其他油类生产绿色柴油的最佳可用技术。通过优化操作参数、处理和改性催化剂以及使用纳米级催化材料，可以提高催化剂的性能。
