2. 與會心得
The Conference was spectacular with its well-organisation and the great number of 650 technical presentations in 12 interest areas such as: Agricultural Microscopy, Analytical, Biotechnology, Edible Applications Technology, Food Structure and Functionality Forum, Health and Nutrition, Industrial Oils Products, Lipid oxidation and Quality, Phospholipids, Processing, Protein and Co-Products, Surfactants and Detergents,. Besides oral presentation, there were also more than 100 poster presentations. Almost all of the topics presented in the Conference are very interesting. However, since some presentation sections took place at the same time so it was impossible to participate in all sessions. In addition to the session (General Industrial Oil Products) that I had my oral, I also attended in sessions such as General Analytical, Biotechnology and others. I also took a general view on poster exhibition. Most speakers are professors or students from USA, Canada, European or Japan. The topics covered in my section are quite interesting, especially some are very helpful and related to my research and there were quite a lot of participants. We had great time in discussion about our research.
The Technician Sections Program, The Conference with more than 100 Cooperated Organizations and Members have provided me a great chance to enrich and update my knowledge on my research and other related topic. Furthermore, Student Group Interest and Mentor program were also held by AOCS which has provided me a chance to make friend from all over the world and I especially appreciate to have the opportunity to communicate with a number of active volunteer members of AOCS from academic, industry or government.
In addition to the oral and poster presentation, the Industry Representatives at the Expo displays also keep me up-to-date on the latest research supplies and new technology
In short, I have gained a lot after attending this conference both on my research and personal skills. This kind of international conference is highly recommended for all students for the great opportunities of learning and broadening knowledge, friendship and science cooperation.
發表之論文: Subcritical Water Assisted Biodiesel Production from Activated Sludge by Lien-Huong Huynh* (黃蓮香), Yi-Hsu Ju (朱義旭)

Abstract
Faced with environment problem and exhaustion of fossil fuel, the idea of utilizing activated sludge as a source of renewable energy has attracted many researchers. Methods on the use of activated sludge as an energy source, such as fermentation, pyrolysis and thermal-gasification for hydrogen production have been investigated. However, due to the complicate nature of sludge, it is difficult to apply those methods for fuel production. Activated sludge has the potential to be used as a raw material for producing biodiesel which is an environmental friendly fuel and an alternative for petro-diesel. Sub-critical water (SCW) treatment of sludge has been known as a cheap and effective method for reducing its organic compound, especially those carcinogenic aromatic PCBs or PAHs. In addition, extractable lipid amount in sludge also increases after SCW treatment.
In this study, dry sludge was firstly subjected to subcritical water treatment. The supernatant (water phase) from the SCW treatment of sludge was collected and centrifuged for further analysis whereas the remaining solid sludge was freeze dried and subjected to solvent extraction. Sludge oil obtained was then dewaxed, degummed to remove wax and phospholipids. Titration and saponification were employed to separate saponifiables lipids from the unsaponifiables in the dewaxed/degummed sludge oil. Composition of the neutral lipids as well as its fatty acid profile were determined and compared to those obtained without SCW treatment.
Keywords: biodiesel, sub-critical water, activated sludge, fatty acids, solvent extraction.
