Abstract

Realizing high catalytic efficiency and stability always be the core guiding principle and continuous optimization in industrial production. Fatty Acid Methyl Esters (FAMEs) are a key component of biodiesel, serving as a renewable, environmentally friendly alternative to conventional petroleum-based diesel fuel. In this study, a series of novel Brønsted acidic cellulose-based ionic liquids (PCM-ILs) were successfully prepared using cellulose as the raw material through chemical grafting and ionic bonding. These PCM-ILs were first applied to catalyze the transesterification of Pistacia chinensis Bunge seed oil for FAMEs production. PCM-ILs can be tailored by varying anions. Under optimal conditions—methanol/oil ratio (10:1), catalyst (10 wt%), temperature (80 °C), and time (6 h)—the FAME yield reached 98.6 %. In addition, the conversion yield remained above 85 % after the prepared catalyst be recycled for six times. Thus, the development of this straightforward and economically viable cellulose-based assembly opens up innovative avenues for the design of high-performance biocatalysts suitable for industrial applications.

期刊介绍： The exploration of energy sources remains a critical matter of study. For the past nine decades, fuel has consistently held the forefront in primary research efforts within the field of energy science. This area of investigation encompasses a wide range of subjects, with a particular emphasis on emerging concerns like environmental factors and pollution.
