Analysis of Palm-Oil-Based Biodiesel in Indonesia using Technological Innovation System Approach

E3S Web of Conferences, 2018
Biodiesel blending mandate has been established in Indonesia since 2006. After 11 years of implementation, the level of biodiesel penetration on the market is still lower than the target.

Synergistic Lewis Acid Photocatalysis Over Cluster‐Defect‐Engineered UiO‐66 for Efficient Liquid Biomass Upgrading

Angewandte Chemie International Edition, EarlyView.
A cluster‐defect engineering strategy is presented for the rational design of Zn‐incorporated UiO‐66 photocatalysts. Selective acid etching mediates hierarchical porosity and abundant Lewis acid sites, tailoring the electronic structure and enhancing light harvesting.

Fractionation and Characterization of Insolubles Formed in Palm Oil Biodiesel

Chemical Engineering Transactions, 2013
During the last decade, biodiesel has emerged as a promising alternative to diesel. However, the sedimentation of some insoluble material in pure biodiesel has become a concern for its producers. This material easily drops out of solution, settles on the bottom of biodiesel storage tanks and forms deposits on vehicle fuel filters.

Effect Soursop Leaf Extract For Oxidation Stability Of Palm Oil Biodiesel and Soybean Oil Biodiesel

IOP Conference Series: Materials Science and Engineering, 2021
Abstract Biodiesel is one of the alternative energy sources for diesel oil substitutes. However, the unsaturated fatty acid contains in vegetable oils leads to the poor oxidation stability of biodiesel. One of the potential methods used to prevent or delay the oxidation reaction is the addition of antioxidants because the process is much

Synthesis of nano-CaO catalyst with SiO2 matrix based on palm shell ash as catalyst support for one cycle developed in the palm biodiesel process

Case Studies in Chemical and Environmental Engineering, 2023
In this research, waste chicken eggshells and palm oil mill boiler ash were utilized as heterogeneous solid base catalysts in biodiesel synthesis. The utilization of solid waste as a catalyst source can increase economic value and is an environmentally ...

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Depression effect of the cold filter plugging point by blending of palm oil, palm stearin, and palm olein biodiesels in petrodiesels

Frontiers in Energy Research, 2022
The cold filter plugging point (CFPP) has been widely used to evaluate the low-temperature operability of neat biodiesel and biodiesel–petrodiesel blends in many European and Asian countries.

Magnetic lipase B from Candida antarctica (CALB) biocatalyst for integrated valorization of tilapia by‐products and biodiesel biorefining

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The immobilization of lipase B from Candida antarctica (CALB) on an amino‐epoxy functionalized magnetic support (Fe3O4‐PEI‐DGEBA) resulted in a highly stable and efficient biocatalyst for biofuel production from tilapia oil. The synthesized support was characterized using scanning electron microscopy, transmission electron microscopy, X‐ray ...

Implementing a palm oil‐based biodiesel policy: The case of Thailand [PDF]

Energy Science & Engineering, 2018
AbstractRenewable energy promotion is recognized as an important goal in international climate policies in order to reduce CO2‐emissions. Biodiesel can potentially be an important contributor in this respect, especially in Thailand with its large biomass production from oil palm cultivation.
