| Resumo: | 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. |
