The energy crises, mainly the rapid depletion of fossil fuels are considered as an important global problem. Thus it necessitates to search for an alternative source of fuel to meet the energy demand. Energy can be produced from different sources among which vegetable oils, non-edible oils and organic waste are considered as potential feed stock for producing biodiesel. Biodiesel is an alternative fuel and it solves the problem of depending on the non-renewable resources. But the major concern with the biodiesel production is that it involves high production cost, purification of the final product and technical constraints associated with the process. Therefore in the recent time, lot of improvements are done with respect to biodiesel production process and the attention is paid for developing process intensification technologies to address the above problems. Various modified methods for producing biodiesel are pyrolysis, supercritical process, ultrasound, reactive distillation, reactive separation, microwave technique and membrane separation. Thus in the current study the biodiesel production from these methods were discussed and the benefits and the drawbacks of these processes were reviewed.

“…However, the nature of ISTE processes involves solid biomass as feedstock making a potential problem for separation of the residual biomass and the immobilized lipase. Gao's group [69][70][71], provided two solutions to this problem: (1) the utilization of indigenous lipase in germinating seed/kernels; (2) the use of catalyst basket made of stainless steel mesh for ease of separation and recovery of the immobilized enzyme. Tran [72] on the other hand immobilized the lipase on Nano Fe 3 O 4 -SiO 2 and recovered the lipase by inducing a magnetic field over the reaction products.…”

“…In conventional process, a small amount of alcohol is added over the reaction duration to avoid such inhibitory effect, which is not applicable in ISTE. To resolve this problem 2 approaches were proposed: the use of cosolvent [69,71]; and the use of alkyl donor less toxic to lipase.…”

“…Hal ini juga dapat mengurangi waktu reaksi dan penggunaan reagen dan co-pelarut [27]. Berdasarkan katalis yang digunakan dalam proses ekstraksi reaktif, metode produksi biodiesel dapat secara luas diklasifikasikan ke dalam dua kategori: berbasis transesterifikasi kimia dan enzimatik [13]. Ekstraksi reaktif menggunakan katalis padat memiliki biaya operasi yang lebih rendah dan lebih kompatibel lingkungan [31].…”

The conventional method for the production of biodiesel needed the oil that is extracted from the biomass before it can be transesterified into fatty acid methyl esters (FAME). Reactive extraction can be used to produce biodiesel with high-yield, low production costs, reduce the reaction time and the use of reagents and co-solvents, making it easier to produce biodiesel. In this study, reactive extraction applied to produce biodiesel from palm fruit mesocarp extracted using dimethyl carbonate as a solvent and reagents, and novozym®435 as a catalyst. Methanol was replaced by dialkyl carbonates, particularly dimethyl carbonate. Dimethyl carbonate can be used as a solvent and as a reagent, so reactive extraction is very easy to apply. The parameters will be study are reaction temperature (50, 60, and 70 °C), reaction time (8, 16, 24 hours), the molar ratio of reactants (50: 1, 60: 1, 70: 1 n/n ), the concentration of novozym® 435 (5%, 10%, 15% wt).The results showed that the highest biodiesel yield can be achivied at conditions temperature of 60 °C, reaction time 24 hours, molar ratio of reactants palm mesocarp to DMC 1:60, and novozym®435 concentration of 10wt%. The results showed that the synthesis of biodiesel via reactive extraction using palm mesocarp as raw material requires a low production cost.
