研究了催化裂化与催化酯化相结合生产类柴油的工艺。得到的最佳工艺条件为：氧化钙为裂解催化剂，蒸馏温度320~350℃，裂解温度480~500℃，废油原料加入量35g/h，酯化催化剂硫酸氢钠用量3wt%，甲醇与热解产物摩尔比0.4。傅立叶变换红外光谱(FTIR)结果表明，催化裂化改变了产物的馏分分布，气相色谱-质谱仪(GC-MS)分析表明，酯化产物由C16以下短链的烷烃、烯烃、醛和脂肪酸甲酯组成。酯化过程中热解产物的酸值由40mgKOH/g显著降低到1.6mgKOH/g。
The process of producing diesel-like fuel from combination of catalytic cracking with catalytic esterification was studied. The optimal technological conditions were obtained as follows: CaO as cracking catalyst, distillation temperature 320 – 350 °C, cracking temperature 480 – 500 °C, adding rate of waste oil feedstock 35 g/h, and sodium bisulfate as esterification catalyst with the amount 3 wt. % of pyrolytic product, and molar ratio 0.4 (methanol to pyrolytic product). Results of Fourier transform infrared spectroscopy (FTIR) indicated that the fraction distribution of product was modified by catalytic cracking process, and gas chromatography-mass spectrometry (GC-MS) analysis showed the esterification products consist of alkanes, alkenes, aldehyde, and fatty acid methyl ester of short chains below C16. And the acid value of pyrolytic product from the esterification process decreased remarkably from 40 mg KOH/g to 1.6 mg KOH/g. The properties of the final fuel product were measured as follows: density ...
