Jatropha curcas oil (JCO) is considered a future feedstock for biodiesel production because it is easily grown in harsh environments and is a non‐edible crop that is not in demand as a food source. Three basic methods are used to produce biodiesel from oils/fats, namely the base‐catalyzed transesterification, acid‐catalyzed transesterification, and enzymatic catalysis. However, heterogeneous transesterification using a solid catalyst rather than a liquid acid or base catalyst is a more environmentally responsible way to utilize crude Jatropha oil for biodiesel production. The use of a heterogeneous catalyst also avoids neutralization and washing steps, thereby leading to a simpler and more efficient process. This paper presents an overview of the production of biodiesel from Jatropha Curcas Linnaeus (JCL) using a heterogeneous catalyst. This review also includes the current economic trend of biofuel production particularly on the production of biodiesel. Different types of conventional and advanced methods like ultrasound, microwave, membrane reactor, supercritical methanol, etc., using several types of heterogeneous catalysts like calcium oxide (CaO), sulfanated zirconia alumina (SZA) and others in the JCO biodiesel transesterification process are discussed in detail. The system design of the transesterification process via process simulation and optimization are also presented. Finally, the persistent challenges facing this process are discussed. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd
