The present work aims at cost-effective approaches for biodiesel conversion from niger seed (NS) oil by employing the transesterification process, Box–Behnken design (BBD), and artificial intelligence (AI) tools. performances of yield are reliant on variables (methanol-to-oil molar ratio M:O, reaction time Rt, catalyst concentration CC, temperature RT). BBD matrices representing parameters were...

To improve the pod-picking efficiency of combine harvester for both peanut seedlings and peanuts, a longitudinal axial flow device is designed in this study. The fixation adjustment modes rod were determined. roller’s rotational speed, diameter, roller, effective rod-picking length, screw-feeding stirrer’s critical parameters determined by theoretical calculation. A combined design quadratic re...

Bio-succinic acid production using microorganisms has been interesting as an environmentally friendly process. Palm oil mill effluent (POME) was considered a cheap substrate to lower the cost of production. It revealed that 2-fold diluted POME produced more succinic than undiluted and 5-fold POME. In addition, effects various neutralizing agents on utilized manage pH CO2 supply indicated utiliz...

In recent years, there has been increasing interest in the functional components of sweet potato because its nutritional and medicinal value. The aim this study is to analyse how much phenolic compounds composition (derived from caffeoylquinic acids) varies as a result cooking. Traditional techniques such as: boiling, oven roasting more processing microwave cooking were tested. Three varieties ...

An ultrasound-assisted method was used to prepare gadolinium oxide (Gd2O3)-zeolitic imidazolate framework (ZIF)-8 nanocomposites. The surface morphology, particle size, and properties of the Gd2O3-ZIF-8 nanocomposites were examined using scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, ultraviolet-visible (UV-vis) spectroscopy. synthesized as a catalyst degrade m...

Microwave assisted extraction (MAE) was investigated for the of total saponins compounds from starfish Echinaster sepositus. In order to achieve optimization microwave and determine influence each operational variable (the solvent concentration (X1), irradiation time (X2), power (X3), liquid-solid ratio (X4)) on saponins, response surface methodology (RSM) coupled with a Box–Behnken design (BBD...

Bamboo waste (BW) was activated with a K2CO3 precursor in microwave process for the adsorption of MB dye from an aqueous solution. The prepared bamboo-waste-activated carbon (BWAC) analyzed by instrumental techniques such as FTIR, SEM, and BET analysis. surface BWAC mesoporous area 107.148 m2/g. removal optimized three variables adsorbent dose, pH, contact time using Box–Behnken design (BBD) mo...

Due to the increasing sales of extended-range hybrid vehicles and increasingly stringent emission regulations for light in China, performance diesel engines range extenders plateau region have attracted attention. In order obtain superior operating at high altitudes, a multi-objective optimization optimal economic point engine was performed an altitude 1960 m. A system model with MC-EGR-VNT (ME...

The source of catalyst and feedstock used for transesterification oil play a significant role in cost, starvation consumers especially edible sources. This investigation aimed at the castor with aid calcined anthill as support. Box Behnken Design (BBD) Response Surface methodology was employed to study relationship among variable production such time (1 – 3 h), temperature (40 60oC), loading 9 ...

Kaolin clay (KN) was employed as an inorganic filler to modify a cross-linked chitosan-glyoxal Schiff’s-based chitosan composite derivative (CTS-GLY). The resulting (CTS-GLY/KN) found be promising synthetic biopolymer that can potentially utilized for color removal well COD reduction of industrial anionic dye (remazol brilliant blue R, RBBR). surface porosity, crystallinity, morphology, functio...
