Why didn't you use the templates they provide?  If you do that, you get the

\documentclass[1p,review,authoryear]{elsarticle}

\usepackage{natbib}
\usepackage[brazil]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}

\begin{frontmatter}

\date{}

\title{My Title)}

\author[focal]{R.~Aluizio\corref{cor1}}
\ead{e-mail address}

\author[focal]{C.A.~Borzone\corref{cor2}}
\ead{e-mail address}

\cortext[cor1]{Principal Corresponding Author}
\cortext[cor2]{Corresponding Author}
\address[focal]{My Address}

\begin{abstract}
My article abstract
\end{abstract}

\begin{keyword}
my \sep keywords
\end{keyword}

\end{frontmatter}
