Metodologia para o estudo da porosidade de dolomita em ensaio de sulfatação interrompida

Abstract: Recebido em 15/1/10; aceito em 21/5/10; publicado na web em 1/9/10 METHODOLOGY FOR THE STUDY OF THE DOLOMITE POROSITY IN ESSAY OF INTERRUPTED SULFATION. The aim of this work is to propose a methodology to evaluate the evolution of the pore blockage of limestone during the sulfation reaction. The experiments were performed for a national limestone (dolomite) with average particle size of 545 μm in interrupted sulfation tests were conducted at seven different times and at three different temperatures of the proc… Show more

“…To provide enough samples for porosimetry tests, calcination tests for both ICB and DP limestones were carried out in a vertical tubular furnace, considering the same experimental conditions of the heating rate, gas flow rate, and temperature adopted in TGA tests. This methodology was described in details elsewhere. , …”

“…This methodology was described in details elsewhere. 30,34 The weights of the samples were 0.600 ± 0.010 g for calcined limestone and 1.000 ± 0.010 g for natural limestone. Before the porosimetry experiments, both calcined and natural samples were dried in an oven for 12 h at 150 °C and degassed (heated and evacuated) for the removal of gases adsorbed inside the particles.…”
