Advancing biodiesel production from microalgae Spirulina sp. by a simultaneous extraction–transesterification process using palm oil as a co-solvent of methanol

Open Chemistry, 2020
Microalgae have been considered as a potential candidate for biodiesel feedstock. Single-stage simultaneous extraction–transesterification process is proposed for simpler and more effective biodiesel conversion. In this study, the experiment of biodiesel

Environmentally Friendly Nanofiber Cellulose From Durian Rinds: A Sustainable Alternative Biomass Resource

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A novel, efficient, and eco‐friendly sustainable process has been developed for the extraction of cellulose nanofibers (CNF) from durian rinds. The method utilizes low‐molecular‐weight 2,2,6,6‐tetramethylpiperidine‐1‐oxyl (TEMPO) as an oxidation agent, in conjunction with sonication treatment, resulting in a significant reduction of processing

Ensiling and Fermentation of Rice Hulls With Ruminal Fluid for Medium‐Chain Carboxylate Production

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Large quantities of rice hulls are common at milling sites in Nigeria. They are a by‐product of rice processing and can contribute to environmental degradation if not properly managed. In this study, rice hulls were pretreated by ensiling at ambient temperature and then used as substrate for medium‐chain carboxylates (MCCs) production ...

Time-Frequency Dynamics of Biofuels-Fuels-Food System

, 2012
For the first time, we apply the wavelet coherence methodology on biofuels (ethanol and biodiesel) and a wide range of related commodities (gasoline, diesel, crude oil, corn, wheat, soybeans, sugarcane and rapeseed oil).

Experimental viscosity measurements of biodiesels at high pressure [PDF]

, 2016
The viscosity of biodiesels of soybean and rapeseed biodiesels blended with mineral diesel fuel were measured at pressures of up to 200 MPa. Using a falling sinker-type viscometer reproducible viscosity data were obtained based on the time taken for a ...

Hydrogen‐Enriched Microbial Oil Biodiesel With Hybrid Nanoparticles Impact on Diesel Engine Efficiency and Emissions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study examines a dual‐fuel enhancement strategy that combines hydrogen enrichment with hybrid nanoparticle (HNP) doping. The aim is to improve combustion, performance, and emission characteristics of microbial oil biodiesel (MOB) in compression ignition engines.

Bioremediation of biodiesel and diesel contaminated soil by pseudomonas putida [PDF]

, 2015
As occurs to the diesel fuel, the commercialization of biodiesel and their diesel blends can cause environmental damages due to accidental spillage. Presence of these contaminants containing polyaromatic hydrocarbons (PAHs) in soil is toxic to humans ...
