生物燃料加氢脱氧催化剂研究进展

综述了近几年国内外生物燃料加氢脱氧催化剂方面的研究现状及进展。贵金属催化剂较传统催化剂具有更强的反应活性，但价格昂贵，贵金属回收也增大了加氢脱氧工艺的成本；过渡金属负载型催化剂虽价格便宜，但易失活；硫化物催化剂虽然具有较高的活性，但制备过程需要预硫化，制备过程复杂；碳、氮化物催化剂价格便宜，且具有与贵金属相似的电子结构和催化活性，被称为"准铂催化剂"；磷化物催化剂作为最具潜力的加氢脱氧催化剂具有较高研究价值。

Advance Research on Hydrodeoxygenation Catalysts of Biofuel

The research progresses on the hydrodeoxygenation catalysts of biofuels were reviewed. Precious metal catalyst had stronger reactivity than the traditional catalyst, but it was expensive and precious metal recovery also increased the cost of hydrodeoxygenation process; transition metal catalyst was cheap, but easy to inactivate; sulfide catalyst had high activity,but the preparation process required pre-vulcanization and the preparation process was complex; carbon and nitride catalysts were inexpensive and had electronic structures and catalytic activity similar to precious metals, known as "quasi-platinum catalysts"; phosphide catalysts as the most promising hydrogen deoxidation catalyst had high research value.
