Thermogravimetric kinetics of crude glycerol [PDF]
Bioresource Technology, 2009 The pyrolysis of the crude glycerol from a biodiesel production plant was investigated by thermogravimetry coupled with Fourier transform infrared spectroscopy. The main gaseous products are discussed, and the thermogravimetric kinetics derived. There were four distinct phases in the pyrolysis process of the crude glycerol.

Crude Glycerol as an Innovative Corrosion Inhibitor
Applied System Innovation, 2018 Crude glycerol, a byproduct of biodiesel production, was evaluated as a potential green inhibitor for steel corrosion in an acidic environment. The study was conducted using steel specimens placed in hydrochloric acid solutions (0.5 M) at a constant room temperature (25 °C) and crude glycerol concentrations in the range 0.1%–1.0% w/w. The criteria used

Characterization of crude glycerol and glycerol pitch from palm-based residual biomass. [PDF]
Biomass Convers Biorefin, 2023 Crude glycerol (CG) and glycerol pitch (GP) are highly alkaline residues from biodiesel and oleochemical plants, respectively, and have organic content which incurs high disposal cost and poses an environmental threat. Characterization of these residues for composition and properties could provide insight into their quality for proper disposal and can ...

Impurities of crude glycerol and their effect on metabolite production [PDF]
Annals of Microbiology, 2013 Glycerol is a valuable raw material for the production of industrially useful metabolites. Among many promising applications for the use of glycerol is its bioconversion to high value-added compounds, such as 1,3-propanediol (1,3-PD), succinate, ethanol, propionate, and hydrogen, through microbial fermentation.

The Use of Crude Glycerol as a Co-Substrate for Anaerobic Digestion. [PDF]
MoleculesOne of the most interesting applications of crude glycerol (CG) is its use for biogas production via the anaerobic co-digestion (AcoD) process. The main aim of the current study was to provide a comprehensive review on the performance of the AcoD of CG mixed with various substrates. For this purpose, analyses were performed for studies available in the
