摘要: The goal of this work is to study the effect thermal pre-treatment Mg/Al mixed oxides (450–1,050 °C) on their structure, basicity and catalytic activity in transesterification rapeseed oil. catalysts was shown depend not only amount basic sites, but also crystallite size MgO, specific surface area population medium/strong sites. Moreover, high stability Mg/Al-550 established by re-using catalyst four times. It associated with negligible magnesium leaching from solid liquid phases.
