“…RSM is an effective statistical technique for optimizing multifactor experiments, building models, evaluating the effects of several parameters for desirable responses. The eventual objective of RSM is to determine the optimum operating parameters for the system, or to determine the region that satisfies the operating specifications [26]. RSM has been reported to optimize the process parameters in biofuel production [27], but this was the first effort that RSM was applied to optimizing the process parameters in order to minimize the energy consumption in UV-A pelleting.…”

Cellulosic biomass can be used as a feedstock for biofuel manufacturing. Pelleting of cellulosic biomass can increase its bulk density and thus improve its storability and reduce the feedstock transportation costs. Ultrasonic vibration-assisted (UV-A) pelleting can produce biomass pellets whose density is comparable to that processed by traditional pelleting methods (e.g. extruding, briquetting, and rolling). This study applied response surface methodology to the development of a predictive model for the energy consumption in UV-A pelleting of wheat straw. Effects of pelleting pressure, ultrasonic power, sieve size, and pellet weight were investigated. This study also optimized the process parameters to minimize the energy consumption in UV-A pelleting using response surface methodology. Optimal conditions to minimize the energy consumption were the following: ultrasonic power at 20%, sieve size at 4 mm, and pellet weight at 1 g, and the minimum energy consumption was 2.54 Wh.

“…The quantitative analysis provides verification that the FAME conversion in biodiesel is greater than 96.5% (mol/mol) in accordance to the specifications reported in EN 14214 [22]. As detailed in EN 14103, the FAME conversion was calculated using Equation (2).…”

“…Prior to use, CaCO 3 was calcined at 800°C for 90 min to remove CO 2 and generate CaO in which the active salt precursor Ca(OH) 2 will be subsequently obtained. Typically, to obtain 45 wt.% calcined CaCO 3 loaded catalyst, 13.5 g of calcined CaCO 3 was added to 200 mL of pure deionized H 2 O in a threeneck flask under magnetic stirring at 700 rpm to prepare an aqueous solution of Ca(OH) 2 . The solution was heated in a closed system at 70°C.…”

“…To date, the majority of heterogeneous ultrasoundassisted transesterification studies utilize refined oils as their feedstock [1,2,6,[9][10][11]. Salamatinia et al [12] have recently reported that biodiesel could be produced from palm, corn, canola, and sunflower oils using ultrasound.…”

Ultrasound-assisted transesterification of refined palm oil (RPO) and crude palm oil (CPO) to produce biodiesel using a palm oil mill fly ash supported calcium oxide (CaO) catalyst is studied in this work. The reaction time is significantly reduced from a maximum of 360 min under conventional mixing to just 30 min with the use of ultrasound. Under ultrasonic cavitation, the required catalyst loading and methanol to oil molar ratio to produce comparable yields and fatty acid methyl esters (FAME) conversions as conventional mixing are lower. For RPO, the ultrasound-assisted transesterification conditions of 60% ultrasonic amplitude, 30 min reaction time, 4 wt.% catalyst loading, and 9:1 methanol to oil molar ratio result in maximum biodiesel yield and FAME conversion of 85.23% and 97.02%, respectively. As for CPO, maximum biodiesel yield of 73.23% and FAME conversion of 97.04% are obtained under the same conditions with the exception of a methanol to oil molar ratio of 12:1. Key physicochemical properties of the produced biodiesels are found to be within the limits set by EN 14214 and ASTM D 6751. Catalyst reusability tests indicate that the catalyst can be used up to three consecutive cycles after regeneration using methanol washing followed by recalcination at 850°C for 2 h.
