また、本発明の均一型高分散金属触媒の製造方法によれば、このように触媒担体にその担体断面全体に亘って触媒金属が分散した状態で担持された均一型高分散金属触媒を容易に製造することができる。
以下、実施例及び比較例に基づいて、本発明の好適な実施の形態を具体的に説明する。
濃度2.67mol/リットルの硝酸アルミニウム水溶液を3900cc調製すると共に、14%アンモニア水溶液を3900cc用意した。30リットルのホーロー容器に純水20リットルを入れ、撹拌しながら70℃に加温した。撹拌を続けながら、硝酸アルミニウム水溶液1300ccを投入して5分間撹拌(pH=2.0)したのちにアンモニア水溶液1300ccを投入して5分間撹拌(pH=7.4)するpHスイング操作を4回行った。得られた水酸化アルミニウムのスラリー水溶液を濾過してケーキを回収し、次いでこのケーキを純水20リットルに再分散させて再び濾過する洗浄操作を3回行い、洗浄ゲルを得た。
この図3に示す結果から明らかなように、硫黄分を含有しない担体を用いて調製した触媒では、白金元素が断面の外殻部に分散担持されていることがわかる。
アルミナ担体Aの調製と同様にpHスイング操作を3回行い、同様に洗浄を行って洗浄ゲルを得た。このゲルに焼成後のアルミナ重量基準で0.5重量%となるように硫黄粉末を添加して均一に混練した。その後は担体Aの場合と同様に成形・乾燥・焼成を行い、硫黄粉末を含むアルミナ担体Bを得た。また、洗浄ゲルに硫黄粉末を添加する際に、ケーキに対して混練するのではなく、ケーキを純水に分散した高濃度のスラリー状態のゲルに対して撹拌しながら硫黄粉末を添加した後に濾過を行い、このケーキを混練器によって十分の混練したゲルから担体Bと同様に調製した硫黄粉末を含むアルミナ担体Cを得た。
濃度0.9mol/リットルの硫酸アルミニウム水溶液を3900cc調製すると共に、14%アンモニア水溶液を3900cc用意した。10リットルのホーロー容器に純水7リットルを入れ、撹拌しながら70℃に加温した。撹拌を続けながら、硫酸アルミニウム水溶液400ccを投入して5分間撹拌(pH=2.0)したのちにアンモニア水溶液300ccを投入して5分間撹拌(pH=7.4)するpHスイング操作を3回行った。得られた水酸化アルミニウムのスラリー水溶液を濾過してケーキを回収し、次いでこのケーキを純水7リットルに再分散させて再び濾過する洗浄操作を2回行い、洗浄ゲルを得た。
図7に示す結果から明らかなように、アルミナ担体の調製工程においてアルミナ源に硫酸塩を利用して合成した後に過剰の硫酸根を洗浄除去することによって硫黄分を含有させた担体を用いて調製した触媒中においても硫黄元素と白金元素とは共に担体全体に亘って略均一に分散し、白金元素の分布パターンは硫黄元素の分布パターンと略一致していることが分かる。
硫黄分を含まない担体Aに濃度0.38mol/リットルの硫酸アンモニウム水溶液を焼成後の硫黄含有量が各々0.1重量%、0.5重量%、1.2重量%となるように含浸して、エバポレーターにて溶媒を除去した後に乾燥(120℃、3時間)、焼成(500℃、3時間)して硫黄分を含むアルミナ担体E(0.1重量%)、F(0.5重量%)、及びG(1.2重量%)を得た。
上記の比較例及び実施例1〜3にて調製された触媒No.1〜No.7の白金の分散度をCOパルス吸着法によって測定した。
以下にCOパルス吸着法について説明する。触媒に対してCOをパルス的に試料に注入すると、導入初期はCOが担持金属表面に吸着され、溶出するCOは少ないが、やがて、ほとんどの担持金属表面にCOが吸着し、定常状態になると、注入したCOのほとんどが溶出されるようになる。このとき、定常時に溶出されるCO量から始めの吸着時の溶出CO量を差し引き、その差分の和をCO吸着量として求める。COパルス吸着法は、この吸着量と担持金属含有量から金属表面積、分散率、粒子径を算出する方法である。以下に具体的な算出方法を説明する。
V=(Vt/W)×{273/(273+t)} (ml/g・cat) … (1)
ここで、試料の金属含有率をC(%)、担持金属の原子量をMとすると、試料1g当たりの担持金属のモル数Rは、
R=(C/100)×(1/M) (mol/g・cat) … (2)
試料1g当たりの吸着ガス量のモル数Kは、
K=V/(22.4×10−3×106) (mol/g・cat) …(3)
これらより、分散度B(担持金属中の有効担持金属の割合)は、
B=(K/R)×100 (%) … (4)
担持金属触媒の格子定数をa(Å)とした時、格子定数面積a2に対して吸着ガス分子1個が吸着するとすれば、金属の比表面積Sは、
S=試料1gに吸着したガス分子数×a2
=K×6.02×1023×(a×10−10)2… (5)
でそれぞれ計算される。
粒子1個の有効面積S=5D2 (m2) … (6)
粒子1個の体積v=D3 (m3) … (7)
試料1g当たりの担持金属の粒子数をnとすると
担持金属の比表面積S=ns=n5D2 (m2) … (8)
担持金属の体積Vc=nv=Nd3 (m3) … (9)
式(10〜11)及び式(10〜12)より、
S/Vc=5/D ∴D=5Vc/S (m) … (10)
担持金属の含有率C(%)、比重をd(g/cm3)とすると、試料1g当たりの担持金属の体積Vcは、
Vc=試料1g当たりの担持金属重量(g/g)/担持金属の比重(g/cm3)
=C/100/d (g/cm3) … (11)
粒子径=5Vc/S
={5(C/100/d)×10−6}/S (m)
={5(C/100/d)×10−6×1010}/S (Å)
として計算される。
硫黄分を含まない担体A、及び硫黄分を含む担体Dを用いて、六塩化ロジウムアンモニウム水溶液を50時間含浸した後に、エバポレーターにて溶媒を除去、乾燥(120℃、3時間)後、焼成(400℃、3時間)して、0.6wt%ロジウム担持アルミナ触媒を得た。EPMAを用いて触媒断面上の硫黄元素及びロジウム元素の存在濃度を面分析及び線分析により定量した結果を図11に示す。
上記各実施例で得られた0.6重量%白金担持アルミナ触媒のうち、触媒No.3(実施例1)、触媒No.4(実施例2)、触媒No.6(実施例3)、触媒No.7(実施例3)及び触媒No.1(比較例)について、メチルシクロヘキサン(MCH)の脱水素反応試験を実施した。内径12.6mmφ×300mmサイズで、反応管断面の中心に外形1/8インチの熱電対用保護管を備えたステンレス製反応管の長さ方向の中心に、触媒層の中心が位置するように上記各触媒10ccを充填し、触媒の上側に予熱層として1mmφの球状α-アルミナビーズ10ccを充填した。水素流通(LHSV=5.0; 50cc/hr)下に触媒層の中心温度が320℃になるまで昇温した。次いでメチルシクロヘキサン(MCH)を高速液体クロマトグラフィ(HPLC)用送液ポンプ(HPLCポンプ)によってLHSV=2.0(20cc/hr)に相当する量を反応器に供給し、直に水素の流量をMCHと水素のガス量の合計量に対して水素のガス量が5mol%になるように調節した。反応中は触媒層の中心温度が320℃になるように電気炉の出力を調整して反応試験を行った。
反応開始2時間後と300時間後におけるMCH転化率(%)、トルエン選択率(%)、トルエン収率(%)、及び水素発生量(cc/h/cc-cat)を求めた。結果を表2に示す。
