“…Studi untuk memanfaatkan bahan alam sebagai katalis heterogen mulai berkembang diantaranya: kitosan-sulfonat (Chamidy and Riniati, 2017), oksida grafin/kitosan (Lin et al, 2017), glutaraldehida-kitosan (Wafiroh et al, 2017), guanidinil-kitosan (He et al, 2015), kitosan (Unlu et al, 2018). Penggunaan kitosan sebagai bahan baku katalis heterogen, tidak lepas dari sifat kitosan yang unik seperti hidrofil dan memiliki gugus reaktif yang memberikan kemudahan modifikasi untuk mendapatkan senyawa yang sesuai dengan kebutuhan penggunaannya (Lusiana, et al, 2019, Saengpracum, et al, 2019.…”

Melalui reaksi taut silang antara kitosan dan asam sitrat, membran kitosanasam sitrat (CC) disiapkan sebagai katalis heterogen dalam proses produksi biodiesel dari minyak kelapa sawit dan metanol. Sifat membran CC dianalisis secara fisikokimia dan menggunakan spektroskopi FTIR dan TGA. Berdasar data fisikokimia, didapatkan bahwa masuknya gugus TPP dalam rangka kitosan berkorelasi dengan peningkatan porositas, hidrofilisitas, serapan air, dan fluks membran. Sisi katalitik dari membran CC pada proses produksi biodiesel dipelajari pada beberapa kondisi konversi. Didapatkan bahwa konversi minyak kelapa sawit mencapai 98,4% dengan kondisi waktu reaksi 75 menit, suhu 70 oC, rasio mol minyak/metanol 1:3 dan jumlah katalis sebesar 70 mg.

“…However, the mechanical strength of the aforementioned material can be improved through irreversible chemical modification of its free amino groups with cross-linking agents. The chitosan chemical modifications have proven efficiency at improvement of mechanical properties and thermal stability . Herein, we use three cross-linking agents to activate the chitosan beads.…”

“…The chitosan chemical modifications have proven efficiency at improvement of mechanical properties and thermal stability. 35 Herein, we use three cross-linking agents to activate the chitosan beads. These surface modifications may be responsible for the mechanical resistance of support during the drying process and biodiesel production since the beads' size remained unchanged and no particle fragments were accumulated in the collection bottle.…”

Enzymatic Transesterification of Coconut Oil Using Chitosan-Immobilized Lipase Produced by Fluidized-Bed System

et al. 2017

This work demonstrated the catalytic performance of Cercospora kikichii lipase immobilized onto chitosan acetate microparticles activated with different cross-linking agents and dried using a fluidized-bed system. The activating agent affected the lipase activity, and the highest immobilizing yield was achieved by the chitosan microparticles activated with 1.5% glutaraldehyde (93.7%) followed by activation with metaperiodate (78.9%) and epichlorohydrin (70.6%). The immobilized biocatalysts produced showed low moisture content and water activity, namely, 3.5% and 0.12, respectively; and high stability under storage conditions maintaining 77.7% of its initial activity after 6 months at 5 °C. The industrial applicability of the biocatalyst was assessed in the transesterification of coconut oil (Cocos nucifera oil) using ethanol as an acylant agent. The viscosity value for the coconut oil (29 mm2·s–1) sharply decreased to 3.2 mm2·s–1, upon the progress of transesterification reaction. This represents a final product containing high ester content (97.9%) and low levels of acylglycerides (0.7%). The stability of chitosan-immobilized lipase was also estimated, under successive batch runs, and after five reuse cycles the ester content remained above 96.5%. Therefore, the immobilization process developed and the immobilized derivative produced could represent an alternative route both for protein engineering (specially for enzyme stability) as for biodiesel production employing lipases.

Biodiesel is considered as a renewable and cleaner fuel compared to the equivalent fossil fuels. However, the conventional methods of biodiesel production as well as its purification processes present economic and environmental limitations. Membrane based systems can significantly improve biodiesel yield retaining the unrecovered feedstock and recycle it to the reactor for further esterification/transesterification. Moreover, the simultaneous removal of byproducts leads in high purity and quality biodiesel production. The current study presents recent experimental and modeling results based on a PRISMA literature review analysis. Several membrane-based catalytic systems were categorized by their performance and stability on biodiesel production as well as by their biodiesel purification for glycerol removal. Findings indicated that high biodiesel yield can be achieved by using catalytic synthesized membranes of different materials; while their stability presents high rate after several runs in batch mode or continuous running mode. In the purification process, glycerol removal over filtration membrane systems seems to be a viable solution for obtaining high quality biodiesel and avoiding wet washing methods that result in wastewater generation. Membrane technology contributes in biodiesel production and purification processes enhancing cost reduction and environmental protection. Nevertheless, more research is required for further industrialization.
