“…Fuel conversion of cotton stalks is a well-researched area [11][12][13][14]. The pyrolysis test researched was carried out inside a captive sample reactor over a temperature range of 400-760C, using an average cotton stalk particle size of 1mm diameter.…”

Pyrolysis is a viable method of extracting combustible fuels as gases or liquids from various, high carbon and hydrogen containing biomaterials. This Meta-study attempts to find the ideal combinations of processes for maximising biofuel output by comparing a range of biomaterials (cotton stalks, algae and peach scraps), put through the two primary methods of pyrolysis, through analysis of reactor type, Temperature, particle size and lower heating value achieved from biofuel output. It is proposed that the fast pyrolysis of Algae in a Fluidized bed reactor at a temperature of 550°C is the optimum combination of parameters for maximising biofuel output in terms of bio-oil yield and lower heating value (LHV) in kJ/kg.

“…However, there was an obvious shoulder peak between 70 °C and 140 °C for all of the heating rates. Munir et al (2009) suggested that the weight loss taking place around 100 °C was partly related to the beginning of the thermal pyrolysis of hemicellulose and lignin in biomass. The major weight loss occurred beyond 140 °C and up to 420 °C, accompanied by two sharp peaks in the weight loss rate.…”

“…The development of a mathematical model predicting the qualities of gaseous products in the processes of gasification and pyrolysis requires the knowledge of the thermal pyrolysis kinetics of biomass (Kumar et al 2008). Researchers have carried out numerous studies on the thermo-physical characterization of different biomass feedstocks, such as corn stover (Kumar et al 2008), cotton stalk (Munir et al 2009;Sun et al 2010;Zhang et al 2016), pine sawdust (Gao et al 2013), apple pomace (Baray et al 2014), sugar cane bagasse (Munir et al 2009;Meng et al 2013), hardwood residues (Mazlan et al 2015), wood lignin (Liu et al 2008), soybean stalk and sorghum stalk (Zhang et al 2016), etc. In addition, the composition and content of the main biomass component can significantly affect the thermal decomposition during the biomass pyrolysis (Zhang et al 2016).…”

Harnessing energy from biomass is environmentally friendly because of the essentially zero net CO2 impact. As a common agricultural byproduct, corncobs are abundant in quantity. This study was carried out to examine the thermo-physical properties of corncobs and characterize the properties of corncob ash produced from gasification, in order to provide a basis for transforming it into value-added products. The results showed that the pyrolysis of corncobs followed a three-step, stepwise mechanism. Activation energies calculated by the Coats-Redfern method at heating rates of 5, 10, and 20 °C/min were 79.08, 76.73, and 75.78 kJ·mol -1 , respectively, implying that the corncobs could be decomposed easily at high heating rates. The emissions of CO, CO2, CH4, H2, H2O, and O2 during pyrolysis corresponded well with thermal curves. Corncob ash could be a good fertilizer because of its high contents of K, P, and Ca. The high SiO2 content makes the corncob ash suitable for ceramics and blended cement concrete. Sylvite (KCl) and quartz (SiO2) were the two major crystal phases in the corncob ash. Relatively large particles of unburnt carbon residues in the ash indicated that low-cost adsorbent could be developed from these carbon residues.

“…The high temperature weight loss is relatively small due to the left over amount of residue. According to Munir et al (2009), the weight loss associated with moisture evaporation and thermal degradation of all raw materials will give an initial weight loss below 100 °C. All series of ceramic composite seemed to be stable, and less decomposition took place at even higher temperatures (Fig.…”

“…The glass-transition temperature (T g ) is the most important property in determining the suitability of a polymer for an engineering application. Despite its importance, determining the underlying mechanisms that govern the T g phenomenon remains one of the outstanding challenges in polymer physics (Munir et al 2009). A study by Ash et al (2004) concluded that the thermal behaviour of polymer composites depends strongly on the matrix polymer and its chemical and morphological characteristics.…”

The aim of this study was to explore the incorporation of biomass carbon nanofillers (CNF) into advanced ceramic. Biomass from bamboo, bagasse (remains of sugarcane after pressing), and oil palm ash was used as the predecessor for producing carbon black nanofillers. Furnace pyrolysis was carried out at 1000 °C and was followed by ball-mill processing to obtain carbon nanofillers in the range of 50 nm to 100 nm. CNFs were added to alumina in varying weight fractions and the resulting mixture was subjected to vacuum sintering at 1400 °C to produce nanobioceramic composites. The ceramic composites were characterized for mechanical, thermal, and morphological properties. A high-resolution Charge-coupled device (CCD) camera was used to study the fracture impact and the failure mechanism. An increase in the loading percentage of CNFs in the alumna decreased the specific gravity, vickers hardness (HV), and fracture toughness values of the composite materials. Furthermore, the thermal conductivity and the thermal stability of the ceramic composite increased as compared to the pristine alumina.
