Solid acid catalyst, sulfated, process for obtaining the same, and process of catalytic esterification of cargo containing fatty acids

摘要

Summary "sulfated solid acid catalyst, production process of the same, and process of catalytic esterification of cargo containing fatty acids", the present invention provides catalysts, solid acid, difunctional, and have a predominance of acidity of bru00f6nsted, mesopor Osidade and low sulfur content.The invention relates to a process for obtaining these catalysts comprising the steps of: (a) sulphation of hydroxide of zirconium or titanium oxide using (NH4) 2SO4 as sulfatante agent; (b) drying; and (c) calcining with controlled air flow and heating rate D And 1 to 10 u00b0 C / min.The invention also relates to the process of catalytic esterification of cargo containing fatty acids, and optionally also glycerides in the presence of alcohol of 1 to 2 carbon atoms, and using such solid acid catalysts. 1 / 1
