Abstract

In this study, an attempt to find a solution for environmental problems as the utilization of the waste of fly ash together with reducing of CO emissions is presented. Zeolite X from fly ash is obtained and used as a catalyst support and this leads to minimization of the catalyst cost. Reference sample synthesized from pure chemicals is modified with the same amount of iron that is content in the fly ash zeolite in order to be compared with it. Platinum is loaded on both samples and the activity for CO oxidation is investigated. The temperature difference for 100% CO conversion (T₁₀₀) on the Pt-loaded fly ash zeolite (FANaX-0.5Pt) and those of Pt modified NaX (NaX0.5 Pt) zeolite is only 20 °C (185 and 165 °C) and there is no difference in this parameter between FANaX-0.5Pt and NaX4.5Fe0.5Pt samples. These results are promising for finding of cheaper alternative of X zeolite.

Pt改性粉煤灰沸石X上的CO氧化

摘要

在这项研究中，尝试寻找一种解决环境问题的方法，例如利用粉煤灰的废物并减少CO的排放。获得了来自粉煤灰的沸石X并将其用作催化剂载体，这导致催化剂成本最小化。由纯化学物质合成的参考样品用与粉煤灰沸石中含量相同的铁进行修饰，以便与之进行比较。在两个样品上均负载了铂，并研究了其氧化CO的活性。100％CO转化的温差（T ₁₀₀）在载有Pt的粉煤灰分子筛（FANaX-0.5Pt）和Pt改性的NaX（NaX0.5 Pt）分子筛上仅20°C（185和165°C），FANaX之间的参数没有差异-0.5Pt和NaX4.5Fe0.5Pt样品。这些结果对于寻找更便宜的X沸石替代品很有希望。
