• RSM was applied to optimize the engine performance and exhaust emissions. Alumina nanoparticle is a good addition for diesel–biodiesel blends improve mitigate emissions of diesel engine. Adding nano-alumina blend significantly increases torque brake power. improves combustion decreases specific fuel consumption. The CO HC were decreased with nano-diesel–biodiesel blends. In this study, combined effect alumina nanoparticles concentration in blended fuels speed on emission characteristics...
There are increasing concerns and growing regulations over contamination environmental pollution. One of the major is pollution caused by mineral oils. As world oil reserves dwindling pressures for finding alternative replacements increasing. Vegetable oils a biodegradable renewable source lubricants. Thus, they seem to be attractive candidates replacement In this study, chemical modification sunflower waste cooking through epoxidation reaction was used improve its physicochemical properties...
In water-scarce regions, the desalination and purification of water wastewater have become critical strategies to address dwindling resources effects prolonged droughts. Particularly in agriculture, largest global consumer water, implementing sustainable solutions is essential. This study investigates greenhouse effluent, utilizing solar energy through a multi-effect distillation process. The simulation was conducted for greenhouses ranging from 500 2000 m² Tehran Province over yearly...
Exhaust pollutants from two-stroke petrol engines are a problem for the environment. Biolubricants new generation of renewable and eco-friendly vegetable-based lubricants, which have attracted lot attention in recent years. In this paper, applicability Technique Order Preference by Similarity to Ideal Solution (TOPSIS) method support process building scoring system selecting an appropriate lubricant has been analyzed. For purpose, biolubricants (TMP-triesters) based on castor oil, palm waste...
Biolubricants are a new generation of renewable and eco-friendly vegetable-based lubricants which have attracted lot attention in recent years. In this research study back-propagation neural network model has been developed for predicting the effect different types biolubricants on performance exhaust emissions 200 cc two stroke engine. The inputs lubricant type, lambda engine speed. Model outputs are: brake power, torque, BSFC (brake specific fuel consumption) include CO, CO2, UHC, O2 NOx...
Dermal absorption is a key parameter in non-dietary human safety assessments for agrochemicals. Conservative default values and other criteria the EFSA guidance have substantially increased generation of product-specific vitro data some cases, vivo data. Therefore, from 190 GLP- OECD guideline-compliant dermal studies were published, suggesting defaults should be revised (Aggarwal et al., 2014). This follow-up article presents an additional 171 also combined dataset. Collectively, provide...
Abstract The reduction in crude oil resources, its volatile prices, and the irreparable environmental pollution caused by their production consumption have led to worrying global challenges. At same time, ever‐increasing population growth growing industrialization resulted an increasing demand for petroleum‐based products, including lubricants. In this respect, proper management of biomass produce higher value‐added products such as biolubricants is very important. Iran, with a more than 80...
In recent years, due to the favorable climate conditions of Iran, cultivation rapeseed has increased significantly. The aim this study was investigate possibility biodiesel production from one genotype (TERI (OE) R-983). An ultrasonic approach used in order intensify reaction. Response surface methodology (RSM) applied identify optimum process. results research showed that conversion found be 87.175% under optimized a 4.63:1 molar ratio (methanol oil), 56.50% amplitude, and 0.4 s pulses for...
Abstract Production of biodiesel from castor oil (CO) using ultrasound-assisted has been investigated in this study. The objective the present work was therefore to determine relationship between various important parameters alkaline-catalyzed transesterification process obtain a high reaction yield short time. response surface methodology (RSM) used statistically analyze and optimize operating process. A central composite design (CCD) approved study effects time, methanol molar ratio,...
Abstract Vegetable oils, whose hydrocarbon structure is very similar to that of petroleum products, are ideal renewable and sustainable alternatives lubricants. Bio-lubricants commonly synthesized by modifying the chemical vegetable oils. In this study, microwave irradiation was applied intensify mass-transfer-limited transesterification reaction produce trimethylolpropane triester (bio-lubricant) from camelina oil as a promising local energy crop. A rotatable RSM-BBD method find optimal...
The cost associated with raw materials for biodiesel production is the most determinant factor in final price and therefore non-edible, easily available, inexpensive feedstocks are envisaged. Pistacia atlantica mutica (PAM) oil-rich abundantly available biomass Iran's jungles that can be considered as a promising energy crop production. Its seeds contained 30% of high quality oil. fatty acid profile PAM oil rich 16–18 carbon chains, close to those petrol-diesel effects ultrasound-assisted...
