Life cycle analysis of Jatropha curcas as a sustainable biodiesel feedstock in Argentina
(Italian Association of Chemical Engineering, 2016-06)
Despite constant changes to the industry in recent years, Argentina remains one of the most important producers of biodiesel in the world. Approximately 90% of the biodiesel produced in Argentina is from soybean, a fact ...
Bioethanol Production from Cachaza as Hydrogen Feedstock: Effect of Ammonium Sulfate during Fermentation
(Energies, 2017)
Cachaza is a type of non-centrifugal sugarcane press-mud that, if it is not employed efficiently, generates water pollution, soil eutrophication, and the spread of possible pathogens. This biomass can be fermented to produce ...
Softwood Lignin as a Sustainable Feedstock for Porous Carbons as Active Material for Supercapacitors Using an Ionic Liquid Electrolyte
(American Chemical Society, 2017-05)
We report on the facile synthesis of porous carbons based on a biopolymer lignin employing a two-step process which includes the activation by KOH in various amounts under an inert gas atmosphere. The resulting carbons are ...
Factors influencing the isobutane yield during the conversion of vacuum gas oil (VGO) under fluidized catalytic cracking (FCC) conditions
(American Chemical Society, 2007-12)
Five equilibrium fluidized catalytic cracking (FCC) catalysts of different types, with unit-cell sizes in the range of 24.23-24.29 Å, were evaluated in the conversion of three commercial vacuum gas oil (VGO) feedstocks in ...
Optimization Approaches for Efficient Crude Blending in Large Oil Refineries
(American Chemical Society, 2018-06)
To increase profit margin, refiners usually upgrade low cost crude oils by mixing them with light crudes to obtain blends of higher value. In recent years, this trend is favored by a shifting in the market demand from ...
Taking into account water use impacts in the LCA of biofuels: An Argentinean case study
(Springer Heidelberg, 2011-08)
Purpose: The assessment of biofuels has until now mainly focused on energy demand and greenhouse gas emissions. Only little attention has been given to other impacts, although the general importance of water use for the ...
Transesterificação do óleo de gergelim em um processo batelada usando etanol supercrítico
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA QUÍMICA, 2019-03-25)
With the increase in the environmental problems generated using fossil fuels,
the search for more renewable and less harmful fuels alternatives have increased, thereby
biodiesel rise as a biodegradable option originated ...
Diseño y evaluación de la producción de alcohol carburante a partir de materias primas lignocelulósicas
(2011)
La producción de etanol aún representa retos tecnológicos, principalmente debido a la complejidad implícita y costo de las materias primas y otros insumos. Sin embargo, este proceso ha sido implementado a diferentes escalas, ...
Evaluación de un carbonizador portátil de bajo costo en la valorización de residuos biomásicos lignocelulósicos
(Instituto Tecnológico de Costa Rica, 2015)
Approximately 40% of residual biomass in Costa Rica is wasted. Lignocellulosic wastes are a part; though they are generated in significant quantities in Costa Rica, they often lack proper management. Their disposal in ...
