Description
本出願は、2017年11月3日に出願された米国仮特許出願第62/581,265号の優先権の利益を主張し、その開示は、その全体が参照により本明細書に組み入れられる。
以下の実施例は、開示の理解を助けるために記載されており、もちろん、本明細書に記載され、請求される実施形態を具体的に限定するものとして解釈されるべきではない。当業者が想達し得る、現在知られているまたは後に開発される全ての均等物の置換を含む、実施形態の変形、および製法の変更または実験計画の若干の変更は、本明細書に組み込まれる実施形態の範囲内であると解釈される。
表面積が291m2/g、支持体2細孔容積が0.41mL/gのチタニア粉末(アナターゼ)を、110℃で一晩乾燥させ、残留水を除去する。メタタングステン酸アンモニウムを脱イオン水に溶解して、約2.4重量%のタングステン金属濃度を有する溶液を得る。従来の溶液滴下含浸法を使用して、約20gの乾燥チタニア粉末に約18gのタングステン溶液を含浸させ、金属として約2.15重量%のタングステンを有する固形物を得る。この固形物を110℃で一晩乾燥させ、400℃で2時間か焼する。クエン酸ビスマスを水酸化アンモニアに溶解して、金属として約12.8重量%のビスマスを含む溶液を得る。この溶液の17gの部分を、溶液滴下含浸技術を使用してチタニアに担持されたタングステンに含浸させて、金属として約9.4重量%のBiを有する材料を提供する。この生成物を110℃で一晩乾燥させ、400℃で2時間か焼する。これをサンプルAとする。
約1mLの吸着剤を反応器に充填する。約100ppmwのアルシンを含む液体プロパンを、周囲温度と約220psigの圧力で反応器に通過させる。液体の空間速度は10h-1に設定されている。反応器を通過する液体流を、アルシン含有量について分析する。実験は、90%の除去効率を示す、約10ppmwのアルシンが反応器を突破するまで行われる。
実施例1を繰り返し、チタニア粉末をチタニア押出物(直径1/8”)で置き換え、クエン酸ビスマスの代わりに硝酸ビスマス(20重量%ビスマス金属原液)を使用する。金属として1.4重量%および6.5重量%のタングステンを有するサンプル(サンプルF)と、金属として約11重量%のビスマスを有するサンプル(サンプルG)を調整する。
実施例2と同様に、「ヒ素取り込み量」を求める。結果を表2に示す。ヒ素取り込み量は、効率90%の時点での新鮮な吸着剤の重量当たりのヒ素の重量%を表す。この量は、吸着剤のアルシン容量の尺度であり、すなわち、アルシン除去効率の尺度になる。
