【摘要】:采用基于結(jié)構(gòu)導(dǎo)向集總的催化裂化MIP工藝反應(yīng)動(dòng)力學(xué)模型對(duì)中國(guó)石化某分公司Ⅰ套催化裂化MIP裝置的操作條件進(jìn)行優(yōu)化,考察了催化裂化產(chǎn)物的平均相對(duì)分子質(zhì)量、汽油收率及汽油中典型組分的含量沿提升管高度的變化情況。實(shí)驗(yàn)結(jié)果表明,一反區(qū)平均相對(duì)分子質(zhì)量隨提升管高度的增加顯著下降,當(dāng)一反區(qū)出口溫度為515℃,劑油質(zhì)量比為6.0時(shí),一反區(qū)平均相對(duì)分子質(zhì)量由712下降為196,表明裂化反應(yīng)主要發(fā)生在一反區(qū);模型優(yōu)化結(jié)果表明,在一反區(qū)出口溫度500~510℃,劑油質(zhì)量比6.5~7.0的條件下,汽油收率高于50%,汽油中烯烴含量低于24%(φ),滿(mǎn)足國(guó)Ⅴ指標(biāo)的要求。為工業(yè)催化裂化MIP裝置的生產(chǎn)提供理論指導(dǎo)。
[Abstract]:The operation conditions of the first set of FCC MIP units in Sinopec were optimized based on the structural steering aggregate MIP process reaction kinetics model. The average molecular weight of FCC products was investigated. The variation of gasoline yield and the content of typical components along the riser height. The experimental results show that the average molecular weight of the first reaction region decreases significantly with the increase of the riser height. When the outlet temperature of the first reaction zone is 515 鈩,
