2、究進(jìn)展。NiP催化劑的制備方法中,TPR法流程相對(duì)簡(jiǎn)單,但所用時(shí)間較長(zhǎng);水熱法和溶劑熱法的物相形成過(guò)程易控、所需反應(yīng)溫度比TPR法低,但制備過(guò)程易發(fā)生顆粒團(tuán)聚、原料昂貴、過(guò)程復(fù)雜的缺點(diǎn)使其不能夠滿足工業(yè)化的要求;熱解法是近些年開發(fā)出的方法,具有反應(yīng)溫度低、制備過(guò)程簡(jiǎn)單等優(yōu)點(diǎn)。向NizP催化劑中引入過(guò)渡金屬、堿土金屬元素均可提高催化劑活性。引入Fe能有效地提高直接脫硫途徑(DDS)的選擇性,其可能的原因是Ni原子和Fe原子形成配位體,產(chǎn)生協(xié)同作用;引入ca能促進(jìn)活性相NizP的形成,提高催化劑HDS催化活性。螯合劑和載體對(duì)NiP催化劑的形成和活性有重要的影
