Evaluation of oil yield of oil Shale by Infrared Spectrometry Coupled with Ultrasound-assisted Extraction

Chemical Research in Chinese Universities 2015年第3期31卷 352-356页

作者： ZHAO Zhenying LIN Jun YU Yong HOU Chuanbin SUN Yuyang College of Instrumentation & Electrical Engineering College of Construction Engineering Jilin University Changchun 130061 P.R.China

The oil yield of oil shale was evaluated by Fourier transform infrared（FTIR） spectrometry coupled with ultrasound-assisted extraction. The extraction conditions, including the amount of sample, extraction time and extrac- tion temperature, were examined and optimized. Twenty-four oil shale samples were collected and divided into calibration set and prediction set randomly with a ratio of 2：1. The oil yields of all the samples were determined by the routine method（low-temperature retorting） for reference. The linear regression（LR） equations of oil yield vs. the total area of the spectrum peaks in a wavenumber range of 3100--2800 cm-1 as well as the sum of absorbance of three absorption peaks（2855, 2927 and 2955 cm-l）, and the multiple linear regression（MLR） model of oil yield vs. the absorbances of the three absorption peaks were constructed with the samples in calibration set and applied to the evaluation of the oil yields of the samples in prediction set, respectively. The results show that the MLR model provides more accurate predictions than the other LR two equations. The determination coefficient（P2p ）, the root- mean-square error of prediction（RMSEP） and the residual prediction deviation（RPD） of the MLR model are 0.9616, 0.6458 and 3.6, respectively. The present method is a rapid and effective alternative to the routine low-temperature retorting method.

Asian Agricultural Research 2023年第10期15卷 17-19页

[Objectives]To explore the extraction conditions of essential oil from eucalyptus leaves.[Methods]The essential oil of eucalyptus leaves was extracted by steam distillation,and the yields of essential oil from eucalyptus leaves under different extraction times,soaking times and different solid-liquid ratios were analyzed through orthogonal test with three factors and three variables.[Results]The effects of various factors on extraction results were:distillation time>solid-liquid ratio>soaking time.When the extraction time and soaking time were 1.5 and 2 h,and the solid-liquid ratio of eucalyptus leaves to distilled water was 1:10,the yield of essential oil was the highest(0.8%).The yield of essential oil increased with the increase of extraction and soaking time,but when reaching the optimal value,the yield decreased with the extension of time.Increasing the solid-liquid ratio can improve the yield of essential oil,but beyond a certain value the yield increased gradually while the cost performance decreased.[Conclusions]The results will provide some reference for the recovery and utilization of eucalyptus leaves.

Molecular Assisted Breeding and Adaptability Analysis of Zhongyouza 11 with Super High oil Content

引用

Agricultural Sciences in China 2007年第11期6卷 1306-1314页

作者： LI Yun-chang HU Qiong MEI De-sheng LI Ying-de XU Yu-song TAN Zu-meng oil Crop Research Institute Chinese Academy of AgricUltural Sciences~National Center for Oil Crops Improvement~Key Laboratory ofMinistry of Agriculture for Oil Crops Improvement Wuhan 430062 P.R. China

Using a three-line system of Shaan 2A cytoplasmic male sterility, a hybrid variety rapeseed, Zhongyouza 11, was developed by the combination of traditional methods and a molecular marker-assisted breeding technique. This hybrid variety had high grain yield, high oil content, wide adaptability, and good quality. The oil content of Zhongyouza 11 is steadily above 43% in the three ecological regions along the Yangtze River valley, which is the largest winter oilseed production area in China. The highest oil content of Zhongyouza 11 reached 46.68% in the upper reaches of the Yangtze River valley in 2003- 2004, which was the highest among all lines involved in the national regional rapeseed variety trials. In the regional yield trials in Hubei Province, the average yield of Zhongyouza 11 reached 2 853 kg ha-1 （2002-2004）, yielding more than the control variety Zhongshuang 6 by 11.34%. In the national trials, the yield of Zhongyouza 11 reached 2 405.7, 2 697.3, and 2770.2 kg ha-1 in the upper, middle, and lower reaches of the Yangtze River valley, yielding more than the control varieties by 11.52, 12.9, and 14.92%, respectively, in 2003-2005. Both the high oil content and high grain yield contributed to the high oil yield of Zhongyouza 11. The oil yield of Zhongyouza 11 in the national trials reached 1 083.3, 1 210.2, and 1224.8 kg ha-1, yielding more than the controls by 29.42, 27.65, and 20.98%, respectively, in the upper, middle, and lower reaches of the Yangtze River valley. The highest oil yield reached 1 369.65 kg ha-1 in the middle reach of the Yangtze River valley （2003-2004）, with an increase of 46.21% compared to the control. The experimental sites distributed widely along the Yangtze River valley, cover most of the Chinese winter rapeseed production areas. Among the 89 experimental location/ years, the yield of Zhongyouza 11 surpassed the controls at 77 location/years in the trials, indicating its wide adaptability. Zhongyouza 11 was the only one that passed the national regional trials in all three regions

Weed Competition Periods Affect Grain yield and Nutrient Uptake of Black Seed(Nigella Sativa L.)

Horticultural Plant Journal 2016年第3期2卷 172-180页

作者： Seyyed Mohammad Seyyedi Parviz Rezvani Moghaddam Mehdi Nassiri Mahallati Department of Agronomy Faculty of AgricultureFerdowsi University of Mashhad

The combination of the relatively open plant canopy and slow growth,especially at early growth stages,results in lower competitiveness of black seed(Nigella sativa L.) than weeds.Thus,weed interference is known as an important factor affecting black seed yield.Therefore,to determine the critical period of weed control and its effects on nutrients uptake of black seed field experiments were conducted in 2011 and 2012.Two quantitative series of weed removal treatments including weed-infested and weed-free treatments were implemented from black seed emergence to maturity harvest.To determine critical period of weed control,plots were weed-infested or weed-free for 0,14,28,42,56,70 days after emergence,in weed-infested and weed-free treatments,respectively.The results revealed that N,P and K contents in weed tissues significantly increased with increasing weed-infested periods during both years of the experiment.The reduction in grain and oil yield due to longer periods of weed-infested conditions or shorter periods of weed-free conditions were accompanied by simultaneous reduction of N,P and K uptake in black seed grains and tissues.Overall,N,P and K contents in weed tissue were found to be 1.8 to 2 times higher than that of black seed.It was concluded that 58 or 49 days weed-free periods are required to avoid yield loss(above 5% or 10%) in black seed.

采用两个品种Hyola308和Hyloa401（Brassica napus L.）,完全随机区组设计,4次重复,在Darab农业实验中心研究了种植密度和播种日期对油菜籽产量及其结构的影响。密度分别为48,67和111株/m2,播种日期分别为2002年10月22日,11月11日和12月1日。结果表明,随着作物密度的增加,收获指数（HI）和种子蛋白质的百分含量显著增加。但是每株的角果数减少了。延迟播种显著降低了每株角果数,每平方米的角果数,千粒重,收获指数和菜籽油的百分含量,但却显著增加了单个角果的种子数和种子的蛋白质含量。播种日期对种子产量没有显著影响,但是第二个播期获得的种子产量、油产量均最高。两品种在每平方米角果数,每角果种子数,千粒重,收获指数和种子蛋白质含量上都有明显的不同。播种日期、种植密度和品种之间的交互作用,对种子产量影响显著,Hyola401在48株/m2时,产量最高。对于这两个品种,延迟播种和增加密度都降低了种子和油的产量。
