In the current study, a seaweed Codium tomentosum was used as a source for the production of biodiesel. The maximum oil from marine macroalgae was recovered using ultrasound-assisted pretreatment. The oil yield was found to be maximum at optimal conditions such as 5% biomass wetness, 0.18 mm biomass size, 6:1 extraction solvent: biomass ratio, extraction temperature, and time as 55 °C and 140 min respectively. The extracted oil was transesterified using solidsolid nanocatalyst produced from waste clay doped with Zn. The maximum biodiesel conversion was found to be 90.5% at optimum conditions. The marine macroalgae C. tomentosum was found to be one of the potential sources for biodiesel production. The techno-economic analysis of the overall biodiesel production (20 MT/batch) process was investigated. The plant payback period is 8.59 years with a positive NPV of 1381 M$/yr.
在本研究中,使用海藻马尾藻作为生产生物柴油的原料。通过超声辅助预处理从海洋大型藻类中提取最大量的油。在最佳条件下,藻浆含水量为 5%,藻浆粒径为 0.18mm,萃取溶剂与生物质的比例为 6:1,萃取温度和时间分别为 55°C 和 140min,发现产油率最高。提取的油用废粘土掺杂 Zn 制备的固-固纳米催化剂进行酯交换反应。在最佳条件下,生物柴油的转化率最高可达 90.5%。海洋大型藻类马尾藻被认为是生物柴油生产的潜在来源之一。对整个生物柴油生产(20 吨/批)过程的技术经济分析进行了研究。工厂投资回收期为 8.59 年,净现值为 1381 百万美元/年。
