“…Carbonaceous coconut shell nanoparticle can be used as reinforcement when carbonized during friction stir processing and welding [4] and can also find application in other reinforcements.It can be used as raw material for activated carbon industries. In all activated carbon producer, coconut shell has been proven to produce top grade active carbon charcoal which got great performance [5], [6], [7], [8].It can be used as filler for synthetic resin glues (thermoset moulding powder) in plywood and laminating board companies [9], [10].It can also be used as compound filler in the production of phenol formaldehyde moulding powder (Bakelite plastic) as filler and extender [11].In South Asian countries, CS-NPs has been used as mosquito repellent by making it into mosquito coils as a burning medium and as a means of controlling fungus in the wood [12].It can be used as lost circulation materials in the oil well drilling companies [13].It can also be used in resin casting, mastic adhesives as well as bituminous products [14].…”

Coconut Shell (CS) as agricultural lignocellulosic biomaterial and agro-waste is predominantly available in India, Malaysia, Nigeria, Thailand, Sri Lanka, and Indonesia. It has proven to have effective durability characteristic, good abstractive resistance, high toughness, and good adsorption properties, and is most suitable for long standing use in many applications such as reinforcement, source of energy, fillers as well as activated carbon and its performance, efficiency and effectiveness depend wholly on whether is in form of nano-, micro-, and macro- particles. In this data, effects of milling time on morphological characteristics was experimented using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and X-Ray Fluorescence (XRF) analyses. The SEM images were taken at magnifications of 1.00kx, 2.00kx and 5.00kx which gives respective 50 µm, 20 µm and 10 µm in different milling time of 0, 20, 40 and 60 mins. Digital Vibratory Disc Milling Machine (VDMM) rated 380 V/50 Hz at 940 rpm was employed for the grinding and the morphology of the milled nanoparticles were characterised. It was revealed from the data collected that 0 min (i.e. 75 µm sieved) has the highest mean area value of 16.105 µm2 and area standard deviation of 200.738 µm2 with least value of a number of particle size distribution of 809 µm. In contrast, 60 mins milled has the lowest values for mean area and area standard deviation of 8.945 µm2 and 115.851 µm2 respectively with the highest number of particle size distribution of 2032 µm. It was observed that milling time increases the number of particle sizes distributions and reduces the area of particle size.

“…In order to enhance the performance of the engine, Vinukumar et al conducted the engine experiment with the addition of coconut shell nanoparticles with diesel and biodiesel blend. Without changing any modification, the engine shows better performance with reduced NOx emission [10]. Similarly, the engine operated with various blends of mahua biodiesel and sardine fish oil biodiesel showed better performance compared to diesel fuel [11,12].…”

Plastic is a resilient, chemically inert, lightweight, and low-cost material. It sticks around in the environment for more than hundred years, threatening nature and spreading toxins. The current study deals with the use of waste polymeric materials and de oiled cake for the production of liquid oil and its blend on the performance and emission characteristics of diesel engine. The tests were conducted in an engine fuelled with diesel and four distinct blends such as 5% (B5), 10% (B10), 15% (B15), and 20% (B20), respectively. The liquid oil was produced by co-pyrolysis of neem de oiled cake (NDC) and waste polystyrene (WPS) in 1 : 2 blend ratio. The raw pyrolysis oil and its different blends were tested for their physical and chemical characteristics in order to find their suitability. Brake power (BP), brake thermal efficiency (BTE), brake-specific fuel consumption (BSFC), emissions of carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) are used to assess the performance of the engine. The experimental results reveal that BTE at all blends is lower than diesel at all loads and the BSFC increases with increasing blend ratio and falls with increasing engine load. At higher loads, the deviation of performance and emission values from baseline diesel up to B10 is very small. It is found from the results that the liquid oil derived from NDC and WPS up to 10% blend will be the promising additive for fossil fuels.

“…Coconut shells, a non-degradable material and an environmental concern could be used as an effective heterogeneous catalyst for biodiesel generation, a green energy source. More interestingly, we could nd only four published papers 319,[321][322][323] in the WOS title search of "biodiesel", "coconut", and "shell" in the period of 1970-2020. Of signicance, the synthesis of new catalysts with low costs and high activity from coconut shells could play crucial roles in the environmental and industrial aspects of green and sustainable catalysts for biodiesel production.…”
