Extraction of Glucose from Kenaf Core Using Mild Acid Treatment
Abstract
Recently, many industries are aiming to reduce the usage of petroleum-based products and synthetic fibres due to increased environmental concerns regarding such materials. This has led to extensive research on natural fibres with the goal of producing eco-friendly products that will replace the existing petroleum-based ones. Natural fibres can be derived from many sources such as plants, animals, or minerals. However, plant fibres, such as kenaf, are more desirable to most researchers. Kenaf, scientifically known as Hibiscus cannabinus. L, has a complex structure because it consists of lignin, cellulose, and hemicelluloses. Due to this reason, kenaf needs to undergo a treatment process in order to remove lignin and hemicellulose, reduce the crystallinity of its constituent cellulose, and increase its porosity. In this study, acid treatment method was employed and the influence of several process parameters, such as temperature and time, for achieving high yield of glucose conversion was studied. The highest substantial glucose yield was 3.4 g/L produced at 200 °C after 60 min.
