在高壓微反裝置上，以正十二烷為模型化合物，對Pt/ZSM-22、Pt/ZSM-23和Pt/ZSM-22/ZSM-23催化劑進行了加氫異構(gòu)反應(yīng)活性評價，結(jié)果表明，在Pt/ZSM-22、Pt/ZSM-23和Pt/ZSM-22/ZSM-23催化劑上，正十二烷的加氫異構(gòu)反應(yīng)轉(zhuǎn)化率、裂解物產(chǎn)率、多支鏈異構(gòu)體收率均隨著反應(yīng)溫度的升高逐漸增大，異構(gòu)十二烷產(chǎn)率和單支鏈異構(gòu)體收率先增加后減少，與Pt/ZSM-22和Pt/ZSM-23催化劑相比較，Pt/ZSM-22/ZSM-23催化劑對長鏈正構(gòu)烷烴表現(xiàn)出更好的加氫異構(gòu)化選擇性，產(chǎn)物分布以單支鏈異構(gòu)體為主。在200ml加氫評價裝置上，以石蠟基200SN脫蠟油、650SN糠醛精制油、蠟下油、加氫裂化尾油、蠟膏和環(huán)烷基VGO為原料油，進一步研究了Pt/ZSM-22/ZSM-23催化劑的加氫異構(gòu)活性、選擇性和穩(wěn)定性，2500小時的反應(yīng)評價結(jié)果表明，Pt/ZSM-22/ZSM-23催化劑具有較好的原料適應(yīng)性和活性穩(wěn)定性，能夠?qū)⒉煌灪康脑嫌娃D(zhuǎn)化成低傾點、高粘度指數(shù)甚至是超高粘度指數(shù)的潤滑油基礎(chǔ)油。 On the high-pressure microreactor device, n-dodecane as a model compound, the hydroisomerization activity evaluation of Pt/ZSM-22, Pt/ZSM-23, and Pt/ZSM-22/ZSM-23 catalyst was carried on, the results indicated that , for the three catalysts, the convertion ratio, yield of cracking products and multi-branched isomers all increased with the increase of reaction temperature,but the yield of i-dodecane and mono-branched isomers first increased and then decreased, compared with Pt/ZSM-22 and Pt/ZSM-23 catalysts, Pt/ZSM-22/ZSM-23 catalyst showed better hydroisomerization selectivity for long chain n-alkanes, products distribution was mainly mono-branched isomers. Hydroisomerization activity,selectivity and stability of Pt/ZSM-22/ZSM-23 catalyst were investigated using the paraffinic 200SN ketone-benzol dewaxing oil, 650SN furfural refined oil , hydrocracking tail oil, foots oil, cerate and naphthenic VGO as feedstocks. The 2500 hours evaluation results indicated that Pt/ZSM-22/ZSM-23 catalyst showed super catalytic performances, including high activity, high hydroisomerization selectivity and broad adaptability to feedstocks. We could obtain low-freezing base oils with high viscosity index or ultrahigh viscosity index in high yield with various wax feedstocks. |

The hydroisomerization activities of Pt/ZSM-22, Pt/ZSM-23, and Pt/ZSM-22/ZSM-23 catalysts were evaluated on the high-pressure microreactor device with n-dodecane as a model compound. It is indicated that , for the three catalysts, the convertion ratio, yield of cracking products and multi-branched isomers all increased with the increase of reaction temperature, while the yield of i-dodecane and mono-branched isomers increased and then decreased with the increase of reaction temperature, and that Pt/ZSM-22/ZSM-23 catalyst showed better hydroisomerization selectivity for long chain n-alkanes than Pt/ZSM-22 and Pt/ZSM-23 catalysts, and the main products were mono-branched isomers. Hydroisomerization activity, selectivity and stability of Pt/ZSM-22/ZSM-23 catalyst were then investigated on 200ml hydrogenation evaluation device with the paraffinic 200SN ketone-benzol dewaxing oil, 650SN furfural refined oil , hydrocracking tail oil, foots oil, cerate and naphthenic VGO as starting materials. It is indicated from the 2500 hours evaluation results that the Pt/ZSM-22/ZSM-23 catalyst showed preferable catalytic performances, including high activity, high hydroisomerization selectivity and good adaptability to starting materials, and that base oils with low pour points and high viscosity index or even ultrahigh viscosity index can be obtained from various wax starting materials with the Pt/ZSM-22/ZSM-23 catalyst. 最后一句有個小改動 |
