There are a number of efficient alternative technologies for the production of fuel‐quality biodiesel from various feedstock types. The solid acid catalyzed transesterification process is one such approach. In this study, the whole process of biodiesel fuel production using solid acid catalysts has been simulated using commercially known software – SuperPro Designer – and the effects of some selected market variables on the economic feasibility of the whole process have been investigated. The market variables considered are oil cost, biodiesel price, alcohol cost, catalyst cost, labor cost, tax variation, maintenance cost, and glycerol selling price. Net present value and project payback time have been used as the parameters for evaluating the effect of changes in these market variables on the economic feasibility of the process. Possible market variations in oil cost and biodiesel price strongly affect the viability of the production process, whereas changes in labor cost and equipment maintenance cost could show less effect. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

使用固体酸催化剂的生物柴油生产工艺：市场变量对工艺经济可行性的影响

有多种有效的替代技术可用于从各种原料类型生产具有燃料品质的生物柴油。固体酸催化的酯交换反应方法就是这样一种方法。在这项研究中，使用商业上已知的软件SuperPro Designer模拟了使用固体酸催化剂生产生物柴油燃料的整个过程，并研究了一些选定的市场变量对整个过程的经济可行性的影响。考虑的市场变量是石油成本，生物柴油价格，酒精成本，催化剂成本，人工成本，税收变动，维护成本和甘油销售价格。净现值和项目投资回收时间已用作评估这些市场变量的变化对流程经济可行性的影响的参数。石油成本和生物柴油价格的可能市场差异会极大地影响生产过程的可行性，而人工成本和设备维护成本的变化可能会产生较小的影响。©2021化学工业协会和John Wiley＆Sons，Ltd
