Description
本実施形態に係るシート状触媒担体用構造体は、所定の金属触媒を担持させ得るシート状の構造体から成るもので、図1に示すように、スラリー生成工程S1と、フロック生成工程S2と、シート化工程S3と、乾燥工程S4と、焼成工程S5とを経ることにより製造されるものである。尚、スラリー生成工程S1の前に、原料としての有機繊維を叩いて解す叩解工程を付加してもよい。
(実施例)
有機繊維5重量部、無機充填材(粉末)80重量部、無機結合剤5重量部、鉱物繊維(繊維長125μm)5重量部、有機結合剤5重量部を所定量の水に混入させスラリーを得た後、その中に高分子凝集剤を投入してフロックを生成し、抄造してシート状の多孔質構造体を得た。その多孔質構造体を乾燥した後、約1300℃で焼成することにより、実施例に係るシート状触媒担体用構造体を得た。
有機繊維5重量部、無機充填材(粉末)85重量部、無機結合剤5重量部、有機結合剤5重量部を所定量の水に混入させスラリーを得た後、実施例と同様に、フロックを生成し、抄造及び乾燥後、約1300℃で焼成することにより、比較例に係るシート状触媒担体用構造体を得た。
実施例のものと比較例のものとの物性を比較するため、3点曲げによる強度の評価(JIS R1601)をそれぞれ行い、その結果を以下の表1に示す。この表1によれば、実施例のものは、鉱物繊維の添加により、比較例のものと比べて曲げ強度が著しく向上することが分かる。
S2 フロック生成工程
S3 シート化工程
S4 乾燥工程
S5 焼成工程
Claims (1)
- 無機充填材、無機結合剤及び凝集剤を含んでなるシート状の多孔質構造体を焼成してシート状の触媒構造体を得る焼成工程を有するシート状触媒担体用構造体の製造方法において、
前記シート状の多孔質構造体は、前記無機充填材、無機結合剤及び凝集剤の他、前記焼成工程における焼成温度直前まで繊維状を保持するとともに、焼成温度にて溶融して焼結作用を生じる鉱物繊維を含有したことを特徴とするシート状触媒担体用構造体の製造方法。
