“…The buffer capacity increases from 11.81 to 19.07 mmol L -1 when the 6-aminocaproic acid is added at concentrations ranging from 20 to 50 mmol L -1 , and at 100 mmol L -1 the buffer capacity does not increase significantly (21.541 mmol L -1 ). The EMD values for I -, NO 3 and S 2 O 3 2-show no significant variation in the range studied and are all close to zero. Therefore, 10 mmol L -1 HCl and 50 mmol L -1 6-aminocaproic acids were chosen for the BGE composition.…”

“…The S 2 O 3 2ion is in excess then the peak broadening is expected. The peak broadening for NO 3 is not a problem because it still has an intense UV absorption signal in 210 nm for the concentration utilized. Table S1 in the Supplementary Information (SI) section contains the data obtained from the simulations carried out in Peakmaster.…”

“…Biodiesel is an important alternative energy source. Compared to mineral diesel, biodiesel has several advantages, such as renewability, biodegradability, no toxic effects on the environment, 1,2 compatibility with diesel engines 2,3 and it usually contains no sulfur or aromatic compounds. 1,4 Biodiesel is produced by a transesterification reaction, where fatty acids are released from triacylglycerols and these react with alcohols to form the corresponding esters.…”

A new and fast method was developed to determine the iodine number of biodiesel samples by capillary zone electrophoresis (CZE). In this procedure, the biodiesel sample reacts with Wijs solution in the presence of a catalyst and all the remaining iodine monochloride is converted to the iodide ion, which is quantified by CZE. Only small amounts of sample and reactant are required and µL level amounts of chloroform and Wijs solution. The reaction time was reduced to 3 min and the total analysis time is less than 15 min. The simplicity and speed of the method can be further enhanced by using single-point calibration. The limits of quantification (LOQ) and determination (LOD) values were better than 0.6 and 0.18 g per 100 g of biodiesel. Instrumental, intraday, and interday precisions were better than 1.13, 1.04 and 6.02% relative standard deviation (RSD). The accuracy was statistically verified by comparison with the standard method EN 14111.

Abstract:Techno-economic assessments (TEA) of biodiesel production may comply with various economic and technical uncertainties during the lifespan of the project, resulting in the variation of many parameters associated with biodiesel production, including price of biodiesel, feedstock price, and rate of interest. Engineers may only collect very limited information on these uncertain parameters such as their variation intervals with lower and upper bound. This paper proposes a novel non-probabilistic strategy for uncertainty analysis (UA) in the TEA of biodiesel production with interval parameters, and non-probabilistic reliability index (NPRI) is employed to measure the economically feasible extent of biodiesel production. A sensitivity analysis (SA) indicator is proposed to assess the sensitivity of NPRI with regard to an individual uncertain interval parameter. The optimization method is utilized to solve NPRI and SA. Results show that NPRI in the focused biodiesel production of interest is 0.1211, and price of biodiesel, price of feedstock, and cost of operating can considerably affect TEA of biodiesel production.
