ABSTRACT

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.

摘要

尽管化石燃料仍然是主要能源，但可再生能源的数量仍在不断增加。由于与化石燃料和其他类型的生物燃料相比具有许多优势，生物柴油是一种有前途的替代燃料。这项研究的特定目标是确定在生物柴油生产和消费的整个生命周期中应用的传统技术与新技术之间的差异。该研究为生物柴油行业的最新进展提供了一些重要的见解，包括微藻类脂质生产生物柴油，先进的均相和酶促酯交换，非催化超临界酯交换，微波和超声辅助技术的应用。考虑到影响生物柴油生产过程的效率和安全性的所有因素，
