Abstract:
Biodiesel is a recommended petroleum-based diesel substitute mainly because it is environmentally friendly and is a renewable, domestic resource. However, compared to petroleum-based diesel, biodiesel has a higher cost, which is the major obstacle to its commercialization. In this thesis, four different continuous alkali- and acid-catalyzed processes to produce biodiesel from virgin vegetable oil and waste cooking oil were designed and simulated. Process flowsheets, along with detailed operating conditions and equipment designs for each process were created. Technical assessment of these proce

Abstract:
The world is moving toward the renewable energy resources. Biogas is a renewable energy resource with high energy value and low CO2 emissions. Biogas is a gas mixture, mainly consisting of methane and carbon dioxide, resulting from the biological process of anaerobic digestion of various organic material. Vegetable oils contain lipids which are excellent substrate for anaerobic digestion as they produce high amount of biogas compared to other substrates like proteins. But one of the major problems attached with the lipids is that they are insoluble in water and form biphasic solution making it

碩士<br>朝陽科技大學<br>環境工程與管理系碩士班<br>95<br>In this study, long-term (80000 km) engine durability tests of both diesel and bio-diesel were performed for the same type of two brand-new engines. The test bio-diesel (B20) was blended with 80% diesel and 20% methyl ester of waste cooking oil. The engines were installed on a standard engine dynamometer with dilution tunnel and were conducted under US transient cycle test to simulate real word driving condition. Regulated (CO, HC, NOx and PM) and polycyclic aromatic hydrocarbons (PAHs) were measured for every 20000 km interval. The results show that using

They are similar to the common heterotrophic bacteria, which relies on the decomposition of organic matter from other organisms. They show absolute demand for sodium, widely distributed in mangroves, sea areas or estuaries. They can produce some high-priced compounds, such as astaxanthin. In this study, the feasibility of algae for production of astaxanthin was to screen the algae strain with the highest astaxanthin content, and the astaxanthin production was increased by using different culture condition

碩士<br>國立成功大學<br>化學工程學系<br>106<br>In this study, lithium metasilicate (Li2SiO3) prepared from fumed silica was used as a heterogeneous base catalyst to catalyze the transesterification reaction of waste cooking oil (WCO) in excess methanol for biodiesel production. Waste cooking oil collected from the local restaurant contained an acid value measured at 1.91 mg KOH/g oil. Li2SiO3 catalyst was synthesized via a hydrothermal process by using fumed silica as a starting material with an addition of LiOH(aq) at 150oC for 2 h. After the hydrothermal reaction, the products were washed thoroughly with

博士<br>國立臺灣科技大學<br>化學工程系<br>106<br>Biodiesel is a renewable fuel derived from vegetable oils or animal fats. Common use of refined vegetable oils as oil feedstock for biodiesel is threat to the sustainability of food in the future. Replacing refined vegetable oils with waste cooking oil potentially solves this problem. Despite of the economic and environmental benefits in the use of waste cooking oil, typical acid- and base-catalyzed biodiesel production process from waste cooking oil often find some problems related to the considerable moisture and free fatty acid content in the waste cooking

Abstract:
Energy is a basic requirement for human existence and its consumption increases every year. Currently, most of the energy needs come from conventional fossil fuels, such as gasoline, liquefied petroleum gas, petrodiesel and natural gas. However, the use of fossil fuels has serious environmental problems associated with it. One of the most promising alternative (renewable) energy sources is biodiesel. Usually the production of biodiesel is a catalyzed process, in which alkaline or acid catalysts are used, for the conversion of triglycerides (transesterification reaction) and free

To produce biodiesel, in this study, a microwave apparatus is utilized for heating in association with a transesterification reaction. In addition, strontium oxide is exploited as a catalyst to expedite the process. Based on the chemical formula, reactant oil as well as alcohol are required. In this experiment, both clean soybean oil and waste cooking oil are tested, and methanol is adopted for the sake of its low cost. To gen

The diesel-WCO-Biodiesel blends were prepared by adding 20% and 40% of waste cooking oil-based biodiesel into to fossil diesel to form W20 and W40, respectively, and they were used as fuels in a diesel fuel engine generator operated at 1.5 and 3.0 kW
