Rapid separation and large-scale synthesis of ß-FeOOH nanospindles for direct coal liquefaction

A rapid separation method for the large-scale synthesis (422 g) of β-FeOOH nanospindles has been achieved via a facile hydrolysis route, including a simple surface-modified process with sodium oleate to improve the dispersivity of β-FeOOH in the direct coal liquefaction (DCL) reaction.

Description
Summary:A rapid separation method for the large-scale synthesis (422 g) of β-FeOOH nanospindles has been achieved via a facile hydrolysis route, including a simple surface-modified process with sodium oleate to improve the dispersivity of β-FeOOH in the direct coal liquefaction (DCL) reaction. The as-prepared (also oleic acid-coated) β-FeOOH exhibited superior catalytic activity toward DCL reaction. The percent of conversion, oil yield, and liquefaction degree with the oleic acid-coated β-FeOOH are 92.6,73.8, and 80.8%, respectively. This facile separation approach allows large-scale production of nanocatalyst without any centrifugation or filtration process, which will be applicable for future industrial DCL processes.
