Acids, like the weak acid present in your can of Coke, can react with oxides to effectively reverse the process of tarnishing. 而酸,比如可乐中的弱酸,和氧化物产生化学反应,能有效避免生锈。
Adding negative catalysts as inorganic acid ( A), oxide ( B) and simple substance ( C) into blending coal, thereby adding them into coke through coking process, the effects of negative catalysts on thermal property of coke was investigated. 通过添加负催化剂的无机酸(A)、氧化物(B)和单质(C)到配煤中炼焦的方式把负催化剂负载到焦炭中,研究了它们对所得焦炭热性质的作用。
We studied the fabricating method of humic acid sodium and forming process of lignite semi-coke and tested strength indexes of moulded coke of different proportioning. 研究了黏结剂腐植酸钠的制备方法及褐煤半焦成型工艺,并对不同配比的型焦作了各种强度指标测试。
The acid distribution of P-RE-USY is more concentrated in the range of intermediate and strong acidity, improving the hydrogen transfer activity. The reduction of strong acid decreases the formation of coke. PREUSY沸石酸性分布更集中在中强酸范围,有利于发生氢转移反应,而强酸数量的降低有利于减少焦炭形成,改善了焦炭选择性。
The results show that catalyst can significantly decrease the degradation temperature of polystyrene, and the acid amount and porous structure of catalyst have important effects on degradation temperature and activation energy of polystyrene and coke yield. 结果表明,催化剂的存在能显著地降低聚苯乙烯的降解温度,催化剂的酸量和孔结构对聚苯乙烯的降解温度、活化能、积炭的生成量及裂解产物有很大的影响。

Study on the Production of D pyroglutamic Acid In this thesis the coke image is processed by using Wavelet Transform. D-焦谷氨酸的研制针对焦块的边缘检测问题,本文进一步应用小波变换技术进行了研究。
Using Humic Acid Sodium as the Binder of Briquetting Fine Coke DEVELOPMENT OF BINDERS FOR FORMING OF BAKING POWDER FROM MOLYBDENUM CONCENTRATE AND ITS BINDING MECHANISM 腐植酸钠用作粉焦成型粘结剂的研究钼精矿焙砂成型粘结剂的开发及作用机理
The results showed that B acid of the catalyst modified by phosphorus was enhanced by 0.02 mmol · g-1, which favored the hydrogen transfer reaction and inhibited coke formation. 结果表明,磷改性使催化剂的B酸中心数量增加了0.02mmol.g-1,而B酸中心的增加有利于双分子的氢转移反应,避免反应过程中催化剂表面的积炭。
Application of wet catalysis process for sulphuric acid production from hydrogen sulphide in coke oven gas sweetening 硫化氢湿式催化法制硫酸工艺在焦炉煤气精制系统中的应用
When the amounts of coke increased and blocked the strong acid sites, the selectivity would increase. If the coke blocked the weak acid sites, the conversion would decrease. 当外表面的积炭量逐渐增加,占据大部分的强酸位时就会使选择性增加,而占据弱酸位的积炭则会使转化率降低。
