Energy valorization of crude glycerol and sanitary sewage in hydrogen generation by biological processes
(2020-04-17)
Biohydrogen production was studied with increased concentrations of crude glycerol (CG) co-digested with sanitary sewage by anaerobic consortium bacteria in anaerobic batch reactors, at 30 °C and initial pH 7.0. The CG was ...
Hydrogen production by crude glycerol steam reforming over Ni-La-Ti mixed oxide catalysts,
(Pergamon-Elsevier Science Ltd, 2017-12)
The production of H2-rich gaseous mixtures from steam reforming of crude glycerol was investigated on ternary Ni-Le-Ti catalysts. Ni-La-Ti mixed oxides containing 15 wt% of Ni and a La/Ti atomic ratio of 1 were prepared ...
The quality of crude glycerine influences the fermentation and nutritive value of Piata grass silage
(Revista Brasileira Zootecnia Brazilian Journal Animal Sci, 2020-01-01)
We aimed to evaluate the effects of crude glycerine purity and levels of glycerol on the fermentative profile, microorganisms counting, and nutritional value of Piata grass silage. The experiment was carried out in a 3x3+1 ...
Glycerol: Production, consumption, prices, characterization and new trends in combustion
(2013-08-14)
The demand for petroleum has been rising rapidly due to increasing industrialization and modernization. This economic development has led to a huge demand for energy, most of which is derived from fossil fuel. However, the ...

Bioconversion of crude glycerol from waste cooking oils into hydrogen by sub-tropical mixed and pure cultures
(2018-01-01)
This study compared the biohydrogen generation by sub-tropical mixed and pure cultures from the crude glycerol from the biodiesel production using waste cooking oils (WCO). The crude glycerol was pretreated by pH adjustment. ...
Raw glycerol re-valuing through etherification with isobutylene: process design and techno-economical assessment
This study evaluates the techno-economic feasibility to produce tert-butyl ethers of glycerol in Colombiausing glycerol obtained from biodiesel production. The major drawback of this process is related to thehigh costs ...
Carcass traits and meat quality of Nellore cattle fed different non-fiber carbohydrates sources associated with crude glycerin
(2016-08-01)
Crude glycerin, a potential energy source for ruminant animals, has been evaluated, mainly, in diets with high starch content. However, a limit number of studies have evaluated the inclusion of crude glycerin in low starch ...
Effect of adding crude glycerine to diets with feed additives on the feed intake, ruminal degradability, volatile fatty acid concentrations and in vitro gas production of feedlot Nellore cattle
(Wiley-Blackwell, 2019-07-01)
The effects of adding crude glycerine with sodium monensin or essential oils to beef cattle diets on the intake, degradability of DM and nutrients, rumen concentration of volatile fatty acids (VFA) and in vitro gas production ...
