“…At higher pressures, the authors noticed considerable reduction in reaction yields and the decrease in the yield for pressures above 194 bar was attributed to negative effects of CO 2 density on enzyme activity [8,19]. Rodrigues et al [3] also reported high yields in the continuous process for biodiesel production in supercritical carbon dioxide for the transesterification of virgin sunflower oil with methanol, Lipozyme TL IM at 200 bar.

“…Supercritical carbon dioxide (SC-CO 2 ) has been proposed as an alternative to the organic solvents to carry out enzymatic transesterification reaction, mainly due to its low critical temperature, below the denaturation temperature of lipase and the relatively good solubility of non-polar compounds, like triglycerides. In addition, SC-CO 2 offers easy product separation, as it can selectively extract/recover the alkyl esters from the reaction mixture since the solubility of the esters in SC-CO 2 is several orders of magnitude higher than the solubility of triacylglycerols and glycerol [3].

“…Recently, Rodrigues et al [3] studied the continuous enzymatic production of biodiesel from virgin and waste sunflower oil in SC-CO 2 , whereas Lubary et al [10] reported integrated synthesis and extraction of short-chain fatty acid ethyl esters using SC-CO 2 . Ciftci and Temelli [11] reported continuous production of fatty acid methyl ester from corn oil in SC-CO 2 catalyst.…”

Green biodiesel production: a review on feedstock, catalyst, monolithic reactor and supercritical fluid technology. Biofuel Research Journal 11 (2016) The advancement of alternative energy is primarily catalyzed by the negative environmental impacts and energy depletion caused by the excessive usage of fossil fuels. Biodiesel has emerged as a promising substitute to petrodiesel because it is biodegradable, less toxic, and reduces greenhouse gas emission. Apart from that, biodiesel can be used as blending component or direct replacements for diesel fuel in automotive engines. A diverse range of methods have been reported for the conversion of renewable feedstocks (vegetable oil or animal fat) into biodiesel with transesterification being the most preferred method. Nevertheless, the cost of producing biodiesel is higher compared to fossil fuel, thus impeding its commercialization potentials. The limited source of reliable feedstock and the underdeveloped biodiesel production route have prevented the full-scale commercialization of biodiesel in many parts of the world. In a recent development, a new technology that incorporates monoliths as support matrices for enzyme immobilization in supercritical carbon dioxide (SC-CO2) for continuous biodiesel production has been proposed to solve the problem. The potential of SC-CO2 system to be applied in enzymatic reactors is not well documented and hence the purpose of this review is to highlight the previous studies conducted as well as the future direction of this technology. © 2016 BRTeam.

Abstract:In recent years, biodegradable and alternative biodiesel has attracted increased attention worldwide. Producing biodiesel from biomass involves critical separation and purification technology. Conventional technologies such as gravitational settling, decantation, filtration, water washing, acid washing, organic solvent washing and absorbent applications are inefficient, less cost effective and environmentally less friendly. In this study supercritical carbon dioxide (SC-CO 2 ) with few steps and a low environmental impact, was used for biodiesel fractionation from impure fatty acid methyl ester (FAME) solution mixes. The method is suitable for application in a variety of biodiesel production processes requiring subsequent stages of purification. The fractionation and purification was carried out using continuous SC-CO 2 fractionation equipment, consisting of three columns filled with stainless steel fragments. A 41.85% FAME content solution mix was used as the raw material in this study. Variables were a temperature range of 40-70 °C, pressure range of 10-30 MPa, SC-CO 2 flow rate range of 7-21 mL/min and a retention time range of 30-90 min. The Taguchi method was used to identify optimal operating conditions. The results show that a separated FAME content of 99.94% was verified by GC-FID under optimal fractionation conditions, which are a temperature of 40 °C of, a pressure level of 30MPa and a flow rate of 7 mL/min of SC-CO 2 for a retention time of 90 min.
