研究了湛江等鞭金藻(Isochrysis zhanjiangensis)在改性ZSM-5分子筛上催化裂解制取低碳烯烃的过程.与热裂解过程相比,湛江等鞭金藻催化裂解可以得到更高的低碳烯烃选择性和收率.同时还研究了湛江等鞭金藻中不同油脂和藻渣的催化裂解.结果表明,微藻中的油脂能有效转化为烯烃,其中中性脂的烯烃收率最高,可达36.7%.不同溶剂抽提后得到的藻渣也可转化为低碳烯烃,但收率远低于微藻中的油脂.微藻中的油脂,特别是中性脂,是烯烃的主要贡献者,提高微藻中的中性脂含量能够得到更高的低碳烯烃收率.
The process of catalytic cracking of Isochrysis zhanjiangensis on the modified ZSM-5 molecular sieve to produce light olefins was studied. Compared with the pyrolysis process, the catalytic cracking of Zhanjiang Isochrysis zhanjiangensis could obtain higher low carbon Olefin selectivity and yield.At the same time, the catalytic cracking of different oils and algae residues in Z. analefensis was also studied.The results showed that the oil in the microalgae could be effectively converted into olefins, of which the neutral olefins had the highest yield of olefins, Up to 36.7% .The algae residue obtained after the extraction of different solvents can also be converted into lower olefins, but the yield is much lower than that of microalgae.The fat and oil in microalgae, especially neutral lipids, are the main olefins Contributors, raising the neutral lipid content in microalgae enables higher yields of lower olefins to be obtained.
