Abstract
ที่ให้วัสดุเชิงประกอบของโลหะออกไซด์ผสมซึ่งประกอบรวมด้วยน้ำหนักของวัสดุ เชิงประกอบนั้น อะลูมินา ในปริมาณในช่วง 1 ถึง 50%; ซีเลีย ในปริมาณในช่วง 1 ถึง 50% เซอร์โค เนีย ในปริมาณในช่วง 10 ถึง 70%; และออกไซด์ของธาตุหมู่ II หนึ่งสารหรือมากกว่า ในปริมาณ ในช่วง 1 ถึง 10%; ในบางครั้ง, มีออกไซด์ธาตุหนึ่ง III หนึ่งสารหรือมากกว่า อยู่ในปริมาณในช่วง 0 ถึง 20% โลหะออกไซด์ผสมเหล่านั้นอาจเป็นวัสดุรองรับแบบรวมที่มีประสิทธิผล สำหรับโลหะมีค่า ที่ใช้ตัวเร่งปฏิกิริยาการปล่อยออก ซึ่งองค์ประกอบเดียวเป็นการรวมของอะลูมินา, ซีเลีย, เซอร์โคเนีย, โลหะหมู่ III ออกไซด์ (ตัวเจือ, ตัวอย่างเช่น, La2O3, Y2O3, Nd2O3,Pr6O11), โลหะหมู่ II ออกไซด์ (สารเติมแต่ง, ตัวอย่างเช่น, BaO, SrO, CaO, MgO), และในบางครั้ง โลหะแทรนซิซันออกไซด์อื่น: Which provides composite metal oxide composite materials including material weight Composite, the amount of alumina in the range of 1 to 50%; Celia in quantities in the range 1 to 50% Zirconia in quantities in the range 10 to 70%; And one or more group II oxides in amounts in the range of 1 to 10%; Sometimes, there is one or more element III oxides. Within a range of 0 to 20%, those mixed metal oxides may be effective combined support materials. For precious metals That use the release catalyst Where a single component is a combination of alumina, celia, zirconia, group III metal oxides (dopants, for example, La2O3, Y2O3, Nd2O3, Pr6O11), group II metal oxides (additives, for example, BaO, SrO, CaO, MgO), and sometimes Other metal transisun oxides:
