determination of the temperature profile within a direct heating<span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">moving bed </span><span style=\"font-family:Verdana;\">torrefier</span> <span style=\"font-family:Verdana;\">in
order to</span><span style=\"font-family:Verdana;\"> determine its minimum column height. A thermal model based on </span><span style=\"font-family:Verdana;\">eulerian-eulerian</span> <span style=\"font-family:Verdana;\">two</span></span><span style=\"font-family:Verdana;\">-</span><span style=\"font-family:Verdana;\">phase</span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\"> solid-gas theory was performed and solved with the
method of lines. </span><span style=\"font-family:Verdana;\">In addition</span><span style=\"font-family:Verdana;\">, this study
allows </span><span style=\"font-family:Verdana;\">to investigate</span><span style=\"font-family:Verdana;\"> the effect of the
biomass particle size on the minimum </span><span style=\"font-family:Verdana;\">torrefier</span><span style=\"font-family:Verdana;\"> column height. This</span></span><span style=\"font-family:Verdana;\"> investigation </span><span style=\"font-family:Verdana;\">was performed by changing, simultaneously, the diameter of particles and
the minimum fluidization velocity of the bed. Then, the calculations were made
for a counter-current torrefaction reactor of 30</span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:;\" \"=\"\"><span style=\"font-family:Verdana;\">cm in diameter and </span><span style=\"font-family:Verdana;\">for</span><span style=\"font-family:Verdana;\"> 5</span></span><span style=\"font-family:;\" \"=\"\"> </span><span style=\"font-family:Verdana;\">kg/h of the feed rate of raw
sugarcane bagasse.</span><span style=\"font-family:Verdana;\"> Results show that the height
of the reactor column must be at least 30 cm for that are 1 mm in diameter and
108 cm for particles that are 2 mm in diameter.</span>
