采用搅拌槽式微量天平流动反应器,在硫化态钴钼催化剂上考察了氢化吡啶及2,6-二甲基吡啶两种含氮毒物对2-甲基呋喃加氢脱氧及2-甲基噻吩加氢脱硫反应的毒化过程。研究发现:钴钼催化剂上加氢脱氧与加氢脱硫活性位均具有空间位阻效应。这... 详细信息

采用搅拌槽式微量天平流动反应器,在硫化态钴钼催化剂上考察了氢化吡啶及2,6-二甲基吡啶两种含氮毒物对2-甲基呋喃加氢脱氧及2-甲基噻吩加氢脱硫反应的毒化过程。研究发现:钴钼催化剂上加氢脱氧与加氢脱硫活性位均具有空间位阻效应。这一事实证明,加氢脱氧与加氢脱硫活性位的中毒是以毒物中氮原子吸附的方式发生的,而不是毒物环上的π键与活性位键合的结果。同时少量毒物2,6-二甲基吡啶吸附于催化剂表面时,不仅未使两种氢解反应中毒,反而产生轻度的促进作用。就此而论,这两种活性位具有相似之处,然而,同一毒物作用下加氢脱氧与加氢脱硫中毒过程的相对活性曲线的明显区别似又表明加氢脱氧位与加氢脱硫位之间存在差异。

By the end of si.ti.s, several satelli.es were launched to observe the earth; among them the Landsat mi.si.ns have been i.portant to study natural resources, especi.lly i. agri.ulture. Currently, Landsat 7, wi.h some problems, and Landsat 5 are useful to evaluate crop development. A project called ＂Parti.i.atory multi.Level eO-assi.ted tools for i.ri.ati.n water management and Agri.ultural Deci.i.n-Support＂（PLei.DeS） was fi.anced by the european Commi.si.n.

An archaeometri. analysi. of the James Ossuary i.scri.ti.n “James son of Joseph Brother of Jesus” strengthens the contenti.n that the ossuary and i.s engravi.gs are authenti.. The bei.e pati.a can be observed on the surface of the ossuary, conti.ui.g gradati.nally i.to the engraved i.scri.ti.n. Fi.e long stri.ti.ns made by the fri.ti.n of falli.g roof rocks conti.uously crosscut the letters. Many di.soluti.n pi.s are superi.posed on several of the letters of the i.scri.ti.n. i. addi.i.n to calci.e and quartz, the pati.a contai.s the followi.g mi.erals: apati.e, whewelli.e and weddeli.e (calci.m oxalate). These mi.erals result from the bi.geni. acti.i.y of mi.roorgani.ms that requi.e a long peri.d of ti.e to form a bi.-pati.a. Moreover, the heterogeneous exi.tence of wi.d-blown mi.rofossi.s (nannofossi.s and forami.i.ers) and quartz wi.hi. the pati.a of the ossuary, i.cludi.g the letteri.g zone, rei.forces the authenti.i.y of the i.scri.ti.n.
