Crude Glycerol and Glycerol as Fuels and Fuel Additives in Combustion Applications

Renewable and Sustainable Energy Reviews, 2022
Biodiesels as renewable fuels are important in approaching low-carbon transportation. One critical challenge associated with biodiesel production is the utilization of crude glycerol, an abundant waste byproduct from which glycerol can be obtained via refinement, to maximize economic and environmental benefits.

Characterization of Crude Glycerol From Biodiesel Plants

Journal of Agricultural and Food Chemistry, 2012
Characterization of crude glycerol is very important to its value-added conversion. In this study, the physical and chemical properties of five biodiesel-derived crude glycerol samples were determined. Three methods, including iodometric-periodic acid method, high performance liquid chromatography (HPLC), and gas chromatography (GC), were shown to be ...

Bioconversion of crude glycerol by fungi

Applied Microbiology and Biotechnology, 2012
The production of synthetic glycerol from petrochemical feedstocks has been decreasing in recent years. This is largely due to increasing supplies of crude glycerol derived as a co-product from the oleochemical industry, especially biodiesel production.

Bioconversion of crude glycerol to glycolipids in Ustilago maydis

Bioresource Technology, 2011
Ustilago maydis is known to produce glycolipid-type biosurfactants. Here, we show that U. maydis is able to efficiently convert biodiesel-derived crude glycerol to glycolipids. We have optimized the medium composition and environmental factors for bioconversion of crude glycerol to glycolipids.

Supported Pt, Pd and Au Nanoparticle Anode Catalysts for Anion-Exchange Membrane Fuel Cells With Glycerol and Crude Glycerol Fuels

Applied Catalysis B: Environmental, 2013
Carbon supported Pt, Pd, and Au nanoparticles (NPs) catalysts with small diameters (2.4-3.5nm) were prepared through a solution-phase reduction method, and applied as the model catalysts for electro-oxidation of both high-purity glycerol and biodiesel ...

Investigating Crude Glycerol Electrooxidation

ECS Meeting Abstracts
Decarbonization of chemical manufacturing requires a range of strategies, including the utilization of process waste. This waste can then be used in processes powered by renewable electricity, such as electrocatalysis, to synthesize other useful chemicals. In doing so, process waste is reduced and industrially-relevant chemicals are produced without

Preparation of Polyurethane from Lignin and Crude Glycerol

2015
Polyurethane foam (PUF) was prepared by a novel approach, using a renewable polyol derived from only biofuel production by-products, lignin and crude glycerol. This could potentially be a high value bio-refinery application for the two byproducts from cellulosic ethanol and biodiesel production, respectively.Renewable polyols were synthesized by the ...

Microbial Conversion of Crude Glycerol to Dihydroxyacetone

Waste and Biomass Valorization, 2014
Glycerol is increasingly being used as a versatile raw material within the biorefinery. However, it is very expensive to refine the crude glycerol to a high purity. In this study, the biotransformation of crude glycerol (79 % purity) using Gluconobacter oxydans spp. oxydans for the production of fine chemical dihydroxyacetone (DHA) was investigated.

Fungal biotransformation of crude glycerol into malic acid

Zeitschrift für Naturforschung C, 2015
Abstract Malic acid production from the biodiesel coproduct crude glycerol by Aspergillus niger ATCC 9142, ATCC 10577 and ATCC 12846 was observed to occur with the highest malic acid level acid being produced by A. niger ATCC 12846.
