Description
本発明に係るCOS加水分解用触媒の実施の形態について説明する。本実施の形態に係るCOS加水分解用触媒は、担体と、担体に担持されたバリウム化合物とを少なくとも含む。
本発明に係るCOS加水分解用触媒の製造方法の実施の形態について説明する。本実施の形態に係るCOS加水分解用触媒は、混練工程と、成形工程と、乾燥工程と、焼成工程とを少なくとも含む。
次いで、図1に、本実施の形態に係る硫化カルボニルの加水分解用触媒を好適に採用できるシステムを示す。図1に示すシステムによれば、本実施の形態に係る触媒を用いて、石炭をガス化した原料ガスからガスタービンでの発電に好適な燃料ガスを精製することができる。
試験例1では、硫酸根を含む二酸化チタン粉末1000gに、酢酸バリウム溶液(酸化バリウム換算で、触媒に対して4質量%)と、10体積%のアンモニア水、3質量%のグラスファイバと、5質量%のカオリンと、5質量%の酢酸セルロースを加え、ニーダーで混練した。得られた混練物を、ハニカム形状の押出ノズルを備えたスクリュー付き真空押出機を用いて、押出成形した。得られたハニカム形状の成形触媒を80℃の条件下で乾燥させ、500℃で5時間焼成することにより、触媒を得た。
試験例1及び試験例2の触媒について、蛍光X線分析法(XRF)により半定量分析を行った。半定量値は、得られた蛍光X線スペクトルから、FP(ファンダメンタル・パラメータ)法を用いて算出した。結果を表1に示す。
試験例1及び試験例2の触媒について、所定の条件のガスを流通させることによって、COSの加水分解反応を行った。圧力は、圧力計により測定した値から算出した絶対圧とした。下記表2に、試験条件を示す。また、各処理温度における触媒出口のCOS濃度をFPD検出器を備えたガスクロマトグラフィにより測定した。下記式に表わすように、下記表2のCOS濃度(触媒入口のCOS濃度)と触媒入口のCOS濃度より、COS変換率を求めた。結果を、図1に示す。
試験例2の触媒について、更に2時間、前述のガスを流通させた。300℃のガスを24時間流通させた触媒を試験例3の触媒とした。試験例3の触媒について、前述と同様に蛍光X線分析法による半定量分析を行った。結果を表3に示す。
