Glycerol, a byproduct derived from the production of biodiesel, is currently in oversupply because of the increase of biodiesel production. One approach to alleviate this problem is to transform glycerol into valuable chemicals or energy. Catalytic steam reforming of glycerol to produce hydrogen (a promising energy vector) could be a valuable option; however efficient catalysts are still under study...
The effect of low glycerol supplementation (<1% v/v) in the thermophilic anaerobic digestion (AD) of real municipal solid waste (RMSW) on methane production (MP) is not known. This study explores the effect of five different glycerol supplementations (0%, 0.1%, 0.25%, 0.5% and 1%) on effluent characteristics, anaerobic consortia and MP. Specifically, by adding 0.25% v/v crude glycerol to the feed,...
Despite the interest in second generation biofuels produced from straw, an increased attention on the by-products (glycerol) of the biodiesel production still remains. With the increase of biodiesel production year by year, new possibilities for glycerol utilization attract more attention. One possible use of glycerol is as a binder material for straw or other biomass pellets production. Thermal behaviour...
This study investigates the possibility of emulsifying bio-oil with crude glycerol to produce emulsion fuels. The focus is on the stability of bio-oil/glycerol (BG) emulsions under various emulsification conditions and the effect of major impurities in crude glycerol. The results suggest that temperature and surfactant play more important roles in BG emulsion stability than stirring speed and time...
A series of rod-like nitrogen-containing carbon-based sulfonic acid functionalized ionic liquids, [PrSO3HN][SO3CF3]/C, with tunable Brønsted acid site densities are fabricated by quaternary ammonization of hydrothermally prepared nitrogen-containing carbon nanorods with 1,3-propanesultone followed by anion exchange with trifluoromethanesulonic acid. The materials are successfully applied in the selective...
Glycerol derived from biodiesel (BD) production is oversupplied and requires urgent utilization. Hence, crude bio-derived glycerol was utilized as a carbon precursor for heterogeneous solid acid catalyst synthesis via partial sulphonation and carbonization in a single step. The as-synthesized catalyst was utilized to catalyze glycerol acetylation reaction with acetic acid to produce oxygenated fuel...
Glycerol, an abundant byproduct in biodiesel industry process, has received a lot of attention in recent years. In this work, a series of glycerol-derived binary and ternary CO2 binding organic liquids (CO2BOLs), were proposed for carbon capture. Physical properties, 1H NMR spectra and FT-IR spectra of these systems were studied to describe the multiple interactions between constituents. The CO2 absorption...
