AI Technical Summary
In existing technologies, the selectivity and yield of C6-12 higher alcohols produced from ethanol are low, the catalyst preparation methods are complex, and a large amount of solvent is required and the synthesis time is long.
A defect-rich HAP catalyst was prepared by solid-phase ball milling. Stoichiometric amounts of calcium source, phosphorus source and ammonium phosphate were added. The ammonia gas generated by the decomposition of ammonium phosphate induced surface defects, thereby improving the adsorption of ethanol molecules and CC coupling ability.
At 325℃ and normal pressure, the selectivity of C6-12 higher alcohols reached 67.5%, and the yield reached 47%. The synthesis steps are simple, the time is short, no waste is generated, and the raw materials are cheap and readily available.
