Sugarcane bagasse: Production, composition, properties, and feedstock potential
(2017-01-01)
Sugarcane is widely cultivated in tropical and subtropical countries around the world, with increasing annual production. The largest sugarcane producing countries are, in millions of tons: Brazil (721), India (347), China ...
Biocatalysts based on nanozeolite-enzyme complexes: Effects of alkoxysilane surface functionalization and biofuel production using microalgae lipids feedstock
(2018-05-01)
Nanozeolites with different crystallographic structures (Nano/TS1, Nano/GIS, Nano/LTA, Nano/BEA, Nano/X, and Nano-X/Ni), functionalized with (3-aminopropyl)trimethoxysilane (APTMS) and crosslinked with glutaraldehyde (GA), ...
Opportunities for the Use of Brazilian Biomass to Produce Renewable Chemicals and Materials
(2021-01-07)
This Review highlights the principal crops of Brazil and how their harvest waste can be used in the chemicals and materials industries. The Review covers various plants; with grains, fruits, trees and nuts all being ...
Using Moringa oleifera Lamarck seed extract for controlling microbial contamination when producing organic cachaça
(2019-11-02)
This study investigated the use of seed extract from Moringa oleifera Lamark (MO) for both clarifying the sugarcane juice and removing fermentation contaminants that originated during the 24 h storage of the freshly cut ...
Effect of resid addition to FCC feedstocks. Assessment in the laboratory
(Touch Briefings, 2011-06)
The decrease in both the quality of crude oil and the demand of fuel oil, together with uncertainty in the oil supply in some countries, contribute to the increasing use of residual feedstocks in refineries. While various ...
Evaluation of the dielectric properties of biodiesel fuels produced from different vegetable oil feedstocks through electrochemical impedance spectroscopy
(ElsevierLondon, 2013-07)
Biodiesel fuels were prepared from different vegetable oil sources (canola, soybean, sunflower, and corn) and studied through electrochemical impedance spectroscopy. The dielectric constant from these biofuels evidenced ...
One-step enzymatic production of fatty acid ethyl ester from high-acidity waste feedstocks in solvent-free media
(2011)
This work aims to demonstrate the enzymatic production of fatty acid ethyl ester biodiesel from highly acidic feedstock in a single-step reaction, without co-solvents and avoiding the inhibition of the enzyme
by ethanol ...
Improving fatty acid methyl ester production yield in a lipase-catalyzed process using waste frying oils as feedstock
(SOC BIOSCIENCE BIOENGINEERING JAPAN, 2010)
The application of waste frying oil (WFO) mixed with rapeseed oil as a feedstock for the effective production of fatty acid methyl esters (FAME) in a lipase-catalyzed process was investigated. The response surface methodology ...
Cultivation of algae in photobioreator and obtention of biodiesel
(Sociedade Brasileira de Farmacognosia, 2011)
In this work we described the cultivation of Chlorella vulgaris in a photobioreactor to algal biomass production. The dried biomass was used as feedstock for biodiesel production, it presented 26% lipids and via sonocatalysis ...
Comprehensive approach of methods for microstructural analysis and analytical tools in lignocellulosic biomass assessment – A review
(2022-03-01)
The trend in the modern world is to replace fossil fuels with green energy sources in order to reduce their environmental impact. The biorefinery industry, within this premise, needs to establish quantitative and qualitative ...
