Barley Straw (Hordeum vulgare) as a Supplementary Raw Material for Eucalyptus camaldulensis and Pinus sylvestris Kraft Pulp in the Paper Industry
Vargas González, Fátima; González, Zoilo; Rojas, Orlando; Garrote, Gil; Rodríguez Pascual, Alejandro (NC State University, 2015)The present study shows that barley straw (Hordeum vulgare) can be a supplementary raw material of softwoods and hardwoods such as Pinus sylvestris and Eucalyptus camaldulensis, respectively, for the production of ... -
Biorrefinería de residuos de la industria agroalimentaria. Valorización de paja de cereales
Vargas González, Fátima (Universidad de Córdoba, UCOPress, 2017)Por una parte, los residuos agrícolas (paja de cereales) se pueden someter a un proceso de pasteado semiquímico con diferentes reactivos. En este trabajo, sosa con o sin adición de antraquinona (este último, proceso Specel®) ... -
Cellulosic pulps of cereal straws as raw material for the manufacture of ecological packaging
Vargas González, Fátima; González, Zoilo; Sánchez, Rafael; Jiménez, Luis; Rodríguez Pascual, Alejandro (NC State University, 2012)The aim of this work was to study the potential application of four types of cereal straws: oats, maize, rapeseed, and barley, in order to obtain cellulose pulp through the Specel® process for use in the manufacture of ... -
Ethanol pulping as a stage in the bio-refinery of olive tree prunings
Requejo Silva, Ana; Rodríguez Pascual, Alejandro; González, Zoilo; Vargas González, Fátima; Jiménez, Luis (NC State University, 2012)Biomaterials from olive tree pruning are an abundant agricultural residue in various Mediterranean regions. A suggested use of this residue is its separation in a main fraction (trunks and stems with diameter > 1 cm) and ... -
Refining of Soda-AQ, Kraft-AQ, and Ethanol Pulps from Orange Tree Wood
González, Zoilo; Rodríguez Pascual, Alejandro; Vargas González, Fátima; Jiménez, Luis (NC State University, 2013)The pulp yield of orange tree wood was tested under various conditions including processing with soda-anthraquinone (soda-AQ), kraft-anthraquinone (kraft-AQ), or ethanol under different temperature, time, reagent concentration, ... -
Total use of olive tree prunings by means of hydrotermal and combustion processes
Requejo Silva, Ana; Feria, Manuel Javier; Vargas González, Fátima; Rodríguez Pascual, Alejandro (NC State University, 2012)The aim of this work is to chemically characterize olive tree prunings and use the material in hydrothermal and combustion processes. The influence of the hydrothermal treatment conditions, with and without acid catalyst, ...
