Abstract

In this study, an investigation on the effect of the Ca/Mg/Zn mixing ratio on gasoline-range hydrocarbon production by oleic basic soap pyrolysis was carried out. The ratios of calcium to magnesium used were 15%, 35%, 50%, 65%, and 85% with constant Zn. Oleic basic soap was obtained by saponification with the modified fusion method. Pyrolysis experiments were carried out at 450 °C using a semi-continuous reactor with a feed flow rate of 5 g/15 min. The process produced three fractions, i.e., gas, solid, and liquid (bio-hydrocarbon + water). The gas products were characterized by GC-TCD, and the results showed the presence of carbon dioxide, hydrogen, nitrogen, oxygen, and methane. Based on the GC-FID and FT-IR results, the bio-hydrocarbon comprised mainly homologous hydrocarbon from carbon number C7 to C19 containing n-alkanes, alkenes, various iso-alkanes, and some oxygenated compounds. All calcium ratios in the oleic basic soap produced hydrocarbon in the range of gasoline (C7-C11) as the dominant product. The maximum yield of gasoline (74.86%) was achieved at 15% calcium.

油酸碱性皂热解生产生物汽油

本文研究了Ca/Mg/Zn混合比对油基皂热解制汽油级烃的影响。在锌含量不变的情况下，钙镁用量分别为15%、35%、50%、65%和85%。采用改进的熔融法制备油基皂。热解实验在450℃半连续反应器中进行，进料流量为5 g/15 min。热解过程产生气、固、液(生物烃+水)三组分。气相色谱- tcd对产物进行了表征，结果表明产物中存在二氧化碳、氢、氮、氧和甲烷。GC-FID和FT-IR结果表明，生物烃主要由碳数为C7 ~ C19的同源烃类组成，含正构烷烃、烯烃、各种异构烷烃和一些含氧化合物。油基皂中各钙比均以汽油(c7 ~ c11)为主导产物。当钙含量为15%时，汽油收率最高，为74.86%。
