Abstract
Description
本発明の利用に関する。
格子内に存在するアルミニウムカチオンに加えて、格子外に非格子アルミニウムカチオンとして存在している相当するカチオンを含んでいる。
(B)工程(A)からのゼオライトを焼成して、適当ならこの前駆化合物を少なくとも一種の遷移金属に変換して、少なくとも一種の遷移金属を含むゼオライトを得る、
(C)硫黄原子及び/又はリン原子またはその前駆化合物を、工程(B)からのドープされたゼオライトに塗布する、
(D)工程(C)からのゼオライトを焼成して本発明により用いられる触媒を得る。
工程(A):
工程(A)は、少なくとも一種の遷移金属またはその前駆化合物のゼオライトへの塗布を含む。
工程(B)では、工程(A)のゼオライトを焼成して、適当なら前駆化合物を少なくとも一種の遷移金属に変換し、少なくとも一種の遷移金属を含むゼオライトを得る。
工程(C)では、硫黄原子及び/又はリン原子またはその前駆化合物が、工程(B)からのドープ後のゼオライトに塗布される。
本方法の工程(D)では、工程(C)からのゼオライトを焼成して本発明で用いられる触媒を得る。
ゼオライトの脱アルミニウムまたは脱金属は、原理的には当業界の熟練者に公知である。
本明細書に記載の方法でこの酸化窒素を安価に除くことができる。
尿素と尿素誘導体が水溶液の形で好ましく用いられる。
粉末状の市販H型ゼオライトを触媒製造の出発原料として用いる。BEA10は、Zeochem社の商品PB/Hであり、MFI17は、同社の商品PZ2/25Hである。FAU40(別名:CBV780)とFER10(別名:CP914C)、BEA140(別名:CBV28014)、MFI15(別名:CBV3020E)は、Zeochem社から購入可能である。BEA140を、450℃で水素雰囲気中で4時間処理して、遷移金属とリン及び/又は硫黄原子を導入する。この過程でゼオライトの結晶性と酸性度が増加する。
このようにして得られた触媒をチューブ反応器に入れて試験する。触媒の量は、いずれの場合も0.5mlである。試験は、1.5bar(a)で、GHSV(時間当たりのガス空間速度)が8000標準lgas/lcat・hで行う。反応器に入るガスと反応器から出るガス中の窒素酸化物含量をGC分析(フレームイオン化検出器)により分析し、排除率または変換率を計算する。
