Abstract

This research investigates the simultaneous reduction of nitric oxide (NOx) and toluene using Pt-based catalysts, aiming at applications in small-scale industrial environmental processes. Catalysts with varying Pt loadings from 0.01 to 3 % were synthesized through wet impregnation, and their dispersion was assessed across several characterizations, revealing effective Pt dispersion even at loadings above 1 %. Under conditions of high toluene feed, the 3 % Pt-loaded catalyst emerged as the most efficient, achieving significant NOx and toluene conversion rates. The performance of this catalyst was thoroughly examined under various operational parameters including NO, toluene, O concentrations, gas hourly space velocity (GHSV) and reaction temperature. A short-stress test further underscored its effectiveness, with NOx and toluene conversions reaching 89.7 % and 97.6 %, respectively. Additionally, a preliminary process simulation of the NOx reduction by toluene indicated an energy efficiency improvement of over 8 % compared to conventional RCO and de-NOx processes. The findings suggest the catalyst's potential for NOx reduction in industrial settings, utilizing toluene present in flue gas without the need for additional commercial reducing agents.

摘要

本研究旨在探索基于铂的催化剂在小规模工业环境过程中的应用，研究其对一氧化氮（NOx）和甲苯的同时还原作用。通过湿浸渍法合成了铂负载量在0.01%至3%之间变化的催化剂，并通过多种表征手段评估其分散性，结果表明即使在负载量高于1%时，铂也能有效分散。在高甲苯进料条件下，负载3%铂的催化剂表现最为高效，实现了显著的NOx和甲苯转化率。在包括NO、甲苯、氧气浓度、气体时空速（GHSV）和反应温度等各种操作参数下，对该催化剂的性能进行了全面研究。短期应力测试进一步证实了其有效性，NOx和甲苯转化率分别达到89.7%和97.6%。此外，对甲苯还原NOx的初步过程模拟表明，与传统的蓄热式催化氧化（RCO）和脱硝工艺相比，能源效率提高了8%以上。研究结果表明，该催化剂在工业环境中利用烟气中存在的甲苯还原NOx具有潜力，无需额外的商业还原剂。
