“…Biomass with lower contents of fixed carbon and ash is very useful upon the pyrolysis, as established by Moral and Sensöz 80 . Also, biomass with lower contents of fixed carbon and ash could produce a higher yield of BO 81 . The HHV of the MCS was comparable with those reported for various biomass sources (Table 5).…”

Mandarin (Citrus reticulata) seeds were exploited as possible nonedible feedstock for the synthesis of liquid biofuels, namely, biodiesel and bio‐oil via alkali–alcoholysis and pyrolysis routes, respectively. The alkali–alcoholysis reaction of mandarin seed oil with an equivalent mixture of methanol–ethanol alcohols was examined and optimized by analysis of variance (ANOVA). The best experimental yield of biodiesel (95.55 ± 1.55 wt.%) was comparable with the predicted yield (95.0 wt.%). Also, analysis by one‐way ANOVA showed that the selected variables were statistically significant. The 1H NMR spectroscopy asserted the transformation of the oil to biodiesel. Also, the evaluated properties of the biodiesel were in the range given by ASTM D6751 standards. The mandarin citrus seeds have also subjected to the thermal pyrolysis process in a fixed‐bed reactor to obtain bio‐oil and bio‐char. The influence of the pyrolysis temperature, time, feed particle size, and heating rate on the bio‐oil yield was optimized. The highest yield of bio‐oil (52.34 ± 1.25 wt.%) was attained at 475°C for 60 min using 70 mesh particle size of the feed with a heating rate of 20°C/min. The bio‐oil was analyzed by Fourier transform infrared spectroscopy (FTIR), 1H NMR spectroscopy, and ultimate analysis. The bio‐oil derived from MCS has an empirical formula of CH1.88 O0.16 N0.012 S0.0005 with 37.96 MJ/kg of heating value. The elevated carbon level, low oxygen content, and high calorific value (25.45 MJ/kg) of the attained bio‐char suggest its suitability as a solid fuel. Also, the obtained bio‐char can be utilized for preparing carbon adsorbent as a result of its good surface area.

“…Thermochemical conversion of biomass has an advantage of being capable of readily producing liquid fuel from any organic matter, most importantly lignocellulosic biomass. 15,41 Pyrolysis is an effective thermochemical process for biomass conversion, which uses an oxygen free environment, and operated at reactor temperatures between 300 °C and 700 °C to produce bio-oil. 15 There are several different reactor designs that have been tested for the production of biooil through pyrolysis including: fluidized bed reactors, ablative pyrolysis reactors, and vacuum pyrolysis reactors, fixed bed reactor.…”

Fast pyrolysis of pinewood sawdust and two of its major components, namely lignin and cellulose was carried out using a laboratory scale induction-heating reactor. The effect of five different temperatures (500°, 550°, 600°, 650° and 700 °C) was tested on the product yield and quality. The products were characterized to evaluate the water content, elemental composition, chemical composition and energy content. The char yield decreased with temperature for all of the biomasses. The maximum liquid yield of 55.28% was achieved at 600 °C for pine sawdust, and the highest liquid yields for cellulose and lignin were obtained at 500 °C. Water content in the liquid fraction decreased as reaction temperature increased. The GC-MS revealed that the bio-oil from cellulose was rich in anhydrosugars while majority of the liquid from lignin had high phenolic contents. Analysis of the gas fraction shows that as the temperature increases the gas yield increases, which, when paired with the declining char masses, showed an increase in the biomass breakdown at higher temperatures. Liquid fraction from pine sawdust has the highest HHV with a peak at 550 °C.

“…Thus, waste cooking oil might be utilized effectively in the production of biodiesel, so as to reduce the raw material cost. This may also help in elucidating the challenge of waste disposal arising from waste cooking oil [19][20][21][22][23][24][25]. Additionally, the high cost of biodiesel production can also be considerably reduced by using catalysts from waste materials.…”

This paper intends to explore the most affordable and environmentally friendly method for the synthesis of biodiesel. Substitute fuel is presently a significant topic all over the world, attributable to the efforts of reducing global warming, which is the result arising from the combustion of petroleum or petrol diesel fuel. Due to its advantages of being renewable and environmentally friendly, biodiesel production has the potential to become the major substitute of petrol diesel fuel. Biodiesel is non-toxic, biodegradable, is produced from renewable sources, and contributes a small amount of greenhouse gas (e.g., CO 2 and SO 2 ) emissions to the atmosphere. Research has established that one of the key obstacles to the commercialization of biodiesel is the high price of biodiesel production due to the shortage of suitable raw materials. However, waste-cooking-oil (WCO) is one of the most cost-effective sources of biodiesel synthesis, and can practically minimize the raw material cost. The research was carried out to produce biodiesel from waste cooking oil in order to reduce the cost, waste, and pollution associated with biodiesel production. The application of a microwave heating system towards enhancing the production of biodiesel from waste cooking oil has been given little consideration in the preceding research, particularly with the application of eggshell as a heterogeneous catalyst. However, the tentative results in this study show significant performance in terms of biodiesel production, as follows: (1) the increasing of the reaction time from 120 to 165 min considerably increased the biodiesel production, which declined with a further rise to 210 min; (2) the results of this study reveal that a methanol-to-oil molar ratio of nine is appropriate and can be used for the best production of biodiesel; (3) the production of biodiesel in this study demonstrated a significant increase in response to the further increasing of power; (4) a 120 min response time, a ratio of 9:1 methanol-to-oil molar fraction, 65 • C temperature; (5) and 5 wt % catalyst were found to be the most ideal reaction conditions during this study. In summary, recycled eggshell was re-used as a suitable catalyst to produce new biodiesel from waste cooking oil, applicable to diesel engines.
