【摘要】：在加氫中試試驗裝置上,以環(huán)烷基減壓蠟油為原料,考察了反應(yīng)溫度、氫分壓等工藝條件對環(huán)保橡膠油C_A值、8種多環(huán)芳烴(PAHs)等性能的影響。結(jié)果表明,在氫分壓為10~15MPa,體積空速為基準~基準+0.5h~(-1),反應(yīng)溫度為t~t+60℃時,加氫工藝適宜生產(chǎn)C_A值12%、苯并(a)芘等8種PAHs質(zhì)量濃度滿足歐盟環(huán)保要求的橡膠油。氫分壓越高,體積空速越小,加氫工藝生產(chǎn)環(huán)保橡膠油的操作空間(反應(yīng)溫度區(qū)間)越寬,且偏向低溫區(qū)間,環(huán)保橡膠油的收率越大。
[Abstract]:In a pilot hydrogenation plant, the effects of reaction temperature and hydrogen partial pressure on the properties of environmental protection rubber oil, such as C A value and 8 polycyclic aromatic hydrocarbons (PAHs), were investigated using naphthenic vacuum wax oil as raw material. The results show that the hydrogenation process is suitable for producing C _ A value of 12 when hydrogen partial pressure is 10m ~ 15MPa, volumetric space velocity is 0.5h-1, reaction temperature is t ~ (t) 60 鈩，
