Alkaline pre-treatment and hydrolysis with acid cellulase of the rice husk (Oryza sativa) for production of bioethanol
(Journal of Physics: Conference Series, 2019-11-19)
Several companies generate large amounts of agroindustrial waste, which could be used as raw material for the production of bioethanol; among them, those that process and commercialize rice, which produce a large amount ...
Mathematical model for production sequencing in a manufacturing company
(Journal of Physics: Conference Series, 2019-11-19)
The objective of the research was to determine the optimal sequence of production of n jobs in m operations, in a small footwear manufacturing company with characteristics of a flow shop machine environment, which minimizes ...
Production of bioethanol from rice husk pretreated with alkalis and hydrolyzed with acid cellulase at pilot scale
(Journal of Physics: Conference Series, 2018-12-07)
Rice husk (RH) is the main biomass byproduct of the rice industry, so much that it corresponds to 20% of the total cereal production and is generally considered a waste. Due to its content of cellulose and hemicellulose, ...
Analysis of folic acid in white rice by ultra-fast liquid chromatography
(Journal of Physics: Conference Series, 2019-11-19)
The method of analysis was standardized, and the folic acid content was determined in samples of fortified white rice (Z, G and D) and unfortified (E and O). The analysis was performed in triplicate in samples of 2.0000 ...
OBTENCIÓN DE PASTA CELULÓSICA A PARTIR DE LA PODA GENERADA DE LOS CULTIVOS DE PALMA DE ACEITE (Elaeis guineensis) DE LA REGIÓN DEL CATATUMBO.
(Universidad Francisco de Paula Santander, 2020-02-02)
El papel, al igual que otros derivados de la pasta de celulosa, como el cartón, son
materiales con una infinidad de usos. Con el desarrollo de la tecnología y el uso de los
computadores se pensaba que el papel desaparecería, ...
Phenomenological modeling and simulation of a textile stenter
(Textile Research Journal, 2020-04-28)
Mathematical modeling and simulation of cotton fabric drying in a stenter machine was performed using a finite element method. A standard κ-ɛ turbulence model was coupled with heat/mass transfer in porous media models. A ...
Production sequencing in a flow shop system using optimization and heuristic algorithms
(Gestao e Producao, 2021-03-31)
The purpose of the research was to determine the sequencing of the production of n
jobs in m operations in a small footwear company in an environment of flow shop machine
characteristics, which optimizes the total time ...
Analysis of caffeine in energy drinks by Ultra-Fast Liquid Chromatography
(Journal of Physics: Conference Series, 2020-08-05)
The objective of this work was to standardize the method of analysis of caffeine and determine its content in three energy drinks (Vive 100, Peak and Red Bull) consumed in the Colombian market, which were selected based ...
Fluid-dynamic study of the behavior of the air inside a textile Stenter
(Journal of Physics: Conference Series, 2021-09-03)
In the textile industry, drying is one of the most important processes. This process requires large investments and high energy consumption, which generates high costs for companies in this sector. In this work, a modeling ...
