Tree peony seeds are rich in α-linolenic acid(ALA), and the peony seed oil is now being produced in China. Paeonia ostii is the most widely used tree peony species for oil extraction, which is commercially called Fengdan and treated as a single cultivar. Here, 50 P. ostii individuals from the same population in northern China were randomly selected for fatty acids(FAs) analysis. Thirteen FAs were isolated, and the most abundant five were palmitic acid(5.31–6.99%), stearic acid(1.22–2.76%), oleic acid(18.78–28.15%), linoleic acid(11.86–26.10%), and ALA(41.11–57.51%). There were significant individual differences of plants in FA quality and quantity and the linoleic acid content in plant No. 48 even exceeded the scope of 1–99%. Further statistical analysis indicated that most of the individual FAs, saturated FAs, unsaturated FAs, and total FAs levels showed significant positive correlations to each other, whereas the seed yield per plant was independent and not correlated to the factors mentioned above. Ward’s hierarchical clustering results grouped the 50 plants into four clusters based on FA contents and seed yield, and the seven plants in Cluster IV were identified as good candidates for oil production. Our results confirmed that the individual differences did occur in P. ostii and Fengdan cannot be simply treated as one uniform cultivar. Also, these results may help simplify the selection of plants for oil peony breeding and accelerate the development of the oil peony industry.

Research and Design in Fire Furnace for oil Transportation

Research and Design in Fire Furnace for Oil Transportation

2011 2nd Asia-Pacific Conference on Wearable Computing Systems

作者： Du Qing Wang Jinhai Zheng Yu Xia Limei School of Information and Communication engineering TJPU

As the fire furnace is being widely used in the industrial production, security and the furnace combustion efficiency become the key factors. We can send signals to the fuel supply device to stop the supply of the fuel when the fire is out by monitoring the flame in the furnace in real time. In this way we can prevent the accumulation of fuel which will cause the explosion and finally make the procedure goes safely. In this design crude oil is heated directly, that means the oil will absorb the heat released by the furnace fuel combustion. UV（ultraviolet） sensor is used to detect the flame in the furnace. Under the specific circumstances of the oil heating furnace, we chose gas as fuel which can be easily got in the oil plant. And more importantly gas will release a lot of UV radiation during the burning of gas, this will make the detection easier and more accurate. The system is very practical and has promising future.

Producing Renewable Biodiesel Fuel Using the Transesterification Process

引用

World Journal of engineering and technology 2015年第3期3卷 105-110页

作者： T. W. Chung Y. J. Chen Department of Chemical engineering Chung Yuan Christian University Taoyuan Taiwan

Biodiesel fuels are considered an alternative to fossil fuels. This is one of the effective means of transferring solar energy to dynamic energy via photosynthesis. It is also being considered in order to reduce the levels of carbon dioxide production worldwide. Biodiesel fuels are a renewable, biodegradable, and clean energy source. Producing enough biofuels to replace fossil fuels will bring the advantages of reduced air pollution and reduced other environmental impacts of fossil fuels. In this study, the response surface methodology (RSM) was used to design the experimental runs and to discuss the manufacturing variables on the transesterification of palm oil into fatty acid methyl ester (i.e. biodiesel fuel). The variation of the degree of effect for each variable in the transesterification process was observed. A second-order model was obtained to predict the yield of biodiesel fuel and the viscosity as a function of the reaction time, the mass fraction of catalyst in methanol and the molar ratio of methanol to plant oil. The experimental data of the yield and the viscosity of biodiesel fuels in different manufacturing variables are discussed in this study. Analysis of variance (ANOVA) was also applied to discuss the main factor and interaction factor effects of the manufacturing variables on the responses of the yield of unrefined biodiesel fuels. The shortage of farmland in Taiwan is a problem that needs to be solved before mass propagation of biofuels can be accomplished. In southeastern Asia, there are many farms and most energy farm products are cultivated (e.g. palm oil or Jatropha oil). In addition to sunflowers and soybeans in Taiwan, those energy farm products are possible choices for production of biodiesel fuel in Taiwan. The cooperation between Indonesia and Taiwan on the plantation of palm or Jatropha trees in Indonesia has conducted and will be one of the possible ways to solve the problem of the shortage of energy farm products in Taiwan.

作者： Barat Ghobadian Mechanics of Agricultural Machinery engineering Tarbiat Modares University (TMU) Tehran Iran

This paper describes a brief review of biodiesel R & D developmental trends at Tarbiat Modares University (TMU) bio- energy research laboratories (lab.), Tehran, Iran. The developmental trends at includes potential and feasibility study, cultivation of a sample bioenrgy farm, technology innovation and its scale up (patents) for fuel processing, and finally the fuel application in diesel engines. A national investigation was carried out to find out the possible potential of sustainable feedstock for biodiesel production. The results showed that easily available biodiesel feedstock is waste cooking oil with a maximum potential of 750 *** and an approximately 350 ***. of collectable waste cooking oil. A castor oil plant farm was cultivated to harvest castor plant seeds, extract its oil, produce biodiesel fuel and use it in diesel engines. This led to a series of patent and consequently technology innovation from 7 lit. lab. scale to semi-continuous, semi-industrial scale of 2 ton capacity.

The European Union Framework Programme 71 Enerfish project aims to demonstrate a new poly-generation application with renewable energy sources for the fishery industry in Vietnam. The fish processing plant under consideration can be made by energy self-sufficient when all fish waste oil is processed into biodiesel and further converted to electricity and heat （for cooling） in a CHP （combined heat and power） unit. The purpose of the present paper is to discuss the profitability of such plants in southeast Asia. The economic model shows that electricity production is, due to the low electricity tariff, uneconomical （except during electricity blackout）, even if cogeneration heat can be utilized. This prompt a design of the plant whereby the necessary heat for the biodiesel process is taken from the waste heat produced by the compressors of a CO2 cooling system. According to the calculations and assumptions of the present study, the profitability of biodiesel production from fish cleaning wastes in Vietnam depends strongly on the market prices for fish waste and fish oil. Different business case scenarios are described.

Investigation was focussed to application of waste POX （partial oxidation）, e.g., meal rape in form of suspension in high boiling hydrocarbons from crude oil distillation. There is an opportunity for utilization of biomass waste resulted from fuels bio-components production. A decrease of oxygen and water steam demand in feed for POX process was observed in this variant. Catalytic effect of iron nanoparticles or nickel nitrate as catalysts in improvement of the pilot plant biomass/oil partial oxidation was investigated as well. Presence of catalyst in the feed supports formation of carbon monoxide and suppression content of methane in the gas product. Experimental data were well compared with process simulation based on eauilibrium reactor model.

针对目前学界有关剪切滑移作用对裂缝中流体渗流研究较少的情况,分析现有研究方法的缺陷,改进现有的研究模型,以固定研究目标尺寸为基础,引入Lattice Boltzmann方法,研究流体在剪切滑移结构中的渗流,并考察非匹配性和接触面积对流体渗流的影响。结果表明:随机二维剖面线可拆分为V型、正弦和凹槽等基本单元体;在基本单元体、二维剖面线中,裂缝面的滑移造成渗流方向上开度分布的非均匀性,渗透率呈现数量级的减小;非匹配情况下的裂缝渗透率比匹配情况下的低,随滑移距离的增加,流体渗流能力均呈先下降后上升趋势;三维裂缝结构的渗透率随滑移距离的增加总体呈下降趋势,下降幅度比基本单元体和二维剖面线结构要低;裂缝面产生剪切滑移时,结构间的非匹配性造成流体渗流轨迹呈三维迂曲性;剪切滑移所造成的非匹配性及接触面积,均对渗流能力有负面作用,但非匹配性可以对裂缝结构起到一定的自支撑作用。
