Diesel fuel is a compound derived from petroleum consisting mainly
of carbon, hydrogen, and low concentrations of sulfur, nitrogen and oxygen. It is
a product that has low flammability, medium toxicity, little volatile, clear, free
from suspended matter and with a strong and characteristic odor. The diesel is
the main liquid fuel sold in Brazil. Currently, it is added 5% of biodiesel to diesel
fuel in order to reduce pollutant emissions. The main objective of this work is to
create a mathematical model that describes the formulations of based diesel
fuels with additives (water / glycerin / surfactant) in order to make the most
energy potential of glycerin and offer less potential polluter possible. The
formulations were developed following a full factorial design type 2
3 with a
duplicate in the midpoint where the independent variables were: Mass of
surfactants (Mt), ratio of surfactants (Prop) and concentration of glycerin
(Sun%). The expected outcome in the process was the mass percentage of
glycerin solution(% BF) supported by diesel, before the turbidity point. In
statistical modeling based on the analysis of Pareto diagram was realized that
all parameters studied were significant to the process. The response surface
methodology was used as an evaluation tool of the optimal point in the process
and a theoretical model was generated to describe the experimental data,
showing a good fit. The calculation of ANOVA revealed that the model obtained
in the study has significant character and predictive. |

Diesel fuel is a compound derived from petroleum consisting mainly of carbon, hydrogen, and low concentrations of sulfur, nitrogen and oxygen. It is a product that has low flammability, medium toxicity, little volatile, clear, free from suspended matter and with a strong and characteristic odor. The diesel is the main liquid fuel sold in Brazil. Currently, it is added 5% of biodiesel to diesel fuel in order to reduce pollutant emissions.

Agência Nacional de Petróleo, Gás Natural e Biocombustíveis (ANP) O óleo diesel é um composto derivado do petróleo constituído principalmente por carbono, hidrogênio, e em baixas concentrações enxofre, nitrogênio e oxigênio. É um produto pouco inflamável, medianamente tóxico, pouco volátil, límpido, isento de material em suspensão e com odor forte e característico. O diesel é o principal combustível líquido comercializado no mercado brasileiro. Atualmente, são adicionados 5% de biodiesel ao óleo diesel com o objetivo de reduzir as emissões de poluentes. O principal objetivo deste trabalho é criar um modelo matemático que descreva as formulações de combustíveis base diesel aditivados com (água/glicerina/tensoativos), a fim de para aproveitar o potencial energético máximo da glicerina e oferecer menor potencial poluidor possível. As formulações foram desenvolvidas seguindo um planejamento fatorial completo do tipo 23 com duplicata no ponto central onde as variáveis independentes estudadas foram: Massa dos tensoativos (Mt), proporção entre tensoativos (Prop) e concentração da solução de glicerina (Sol%). O resultado esperado no processo foi à porcentagem mássica da solução de glicerina (%MG) suportada pelo diesel, antes do ponto de turbidez. Na modelagem estatística a partir da análise do diagrama de Pareto percebeuse que todos os parâmetros estudados foram significativos ao processo. A metodologia de superfície de resposta foi utilizada como ferramenta de avaliação do ponto ótimo do processo e um modelo teórico foi gerado para descrever os dados experimentais, mostrando um bom ajuste. O calculo da ANOVA revelou que o modelo obtido no estudo tem caráter significativo e preditivo. 2016-03-21T19:02:41Z 2021-09-27T12:25:15Z 2016-03-21T19:02:41Z 2021-09-27T12:25:15Z 2015 bachelorThesis 2011079924 COSTA, Pedro Henrique Pereira da.
