“…In another investigation, biochar produced from chicken manure using a batch-type tubular pyrolysis reactor was used as a green catalyst to produce biodiesel (fatty acid methyl ester). The pseudo-catalytic transesterification reaction performance of chicken manure biochar compared well against commercially available porous materials (SiO 2 ), resulting in 95.6% fatty acid methyl ester yield at 350 • C. The study also recommended that in order to avoid thermal cracking of inorganic species (Ca) in chicken manure biochar, it should be produced at temperatures lower than 350 • C [15]. The pattern of product gas evolution during the pyrolysis and gasification of chicken manure was studied at different temperatures and oxygen enrichment in a batch reactor, and the authors concluded that the cumulative energy yields from the gasification process were higher compared to pyrolysis [16].…”

Livestock production is among the most rapidly growing sectors of the agricultural economy driven primarily by growing demand for animal protein, but also posing significant waste disposal issues and environmental impacts. Moreover, opportunities exist for utilising animal waste at the farm level for heat and power generation (thermal conversion) which can contribute to economic sustainability and also provide a bio-fertiliser for soil amendment. The present study is focused on energy and nutrient recovery from poultry litter using a thermochemical conversion technology (fast pyrolysis). The formation of products (gases, biochar and bio-oil) during the fast pyrolysis of poultry litter was experimentally investigated in a laboratory-scale bubbling fluidised bed reactor. Pyrolytic gases accounted for 15–22 wt.% of the product. The carbon content in biochar increased from 47 to 48.5 wt.% with an increase in the pyrolysis temperature. Phosphorous and potassium recovery in the biochar were over 75%, suggesting that it could be used as an organic soil amendment. The high ash content in poultry litter (14.3 wt.%) resulted in low bio-oil and high biochar yield. The bio-oil yield was over 27 wt.% with a higher heating value of 32.17 MJ/kg (dry basis). The total acid number of the bio-oil decreased from 46.30 to 38.50 with an increase in temperature. The nitrogen content in the bio-oil produced from the poultry litter (>7 wt.%) was significantly higher compared to bio-oil produced from the wood (0.1 wt.%).

“…Given the negligible cost of the feedstock, the direct use of waste materials rather than chemical reagents to prepare the base catalyst in transesterification reactions has drawn increased attention. Some waste materials have been used as the feedstock for preparing base catalysts, including eggshell (Gupta et al 2018), chicken manure (Jung et al 2017), fish waste (Shikhaliyev et al 2018), marine barnacle (Manaf et al 2018), disposable diapers (Wang et al 2019), and oil palm empty fruit bunch (Okoye et al 2019). Therefore, utilizing waste materials to prepare a base catalyst can allow for new ways to synthesize GC using the transesterification of glycerol with DMC.…”

Corncob was calcined within a temperature range of 300 °C to 700 °C to prepare a series of corncob residue catalysts for the transesterification of glycerol with dimethyl carbonate (DMC) to synthesize glycerol carbonate (GC). Among the catalysts, the corncob residue catalyst obtained through calcination of corncob at 500 °C (CCR-500) showed a relatively high basicity and satisfactory catalytic activity. The structural investigation results indicated that CCR-500 was composed of carbon material and some alkaline mineral salts. Using CCR-500 as the catalyst, a glycerol conversion of 98.1% and a GC yield of 94.1% were achieved when the reaction was performed at 80 °C for 90 min, with a catalyst amount of 3 wt% and glycerol to DMC molar ratio of 1:3. The comparison of CCR-500 with the reported catalysts indicated that the CCR-500 was a low-cost, high-active, and easily-accessible catalyst for the transesterification of glycerol with DMC.

“…The edible oil mainly includes vegetable oil and animal oil, which are mainly composed of fatty acid or ester with long chain. Fatty acid or ester usually contains rich carbon resources with C 12 -C 24 bonds [5,6]. Therefore, the successful transformation of fed oil to biodiesel may effectively mitigate the current tense energy situation.…”

A series of Ni/KIT6 catalyst precursors with 25 wt.% Ni loading amount were reduced in H 2 at 400, 450, 500, and 550 • C, respectively. The studied catalysts were investigated by XRD, Quasi in-situ XPS, BET, TEM, and H 2 -TPD/Ranalysis methods. It was found that reduction temperature is an important factor affecting the hydrodeoxygenation (HDO) performance of the studied catalysts because of the Strong Metal Support Interaction Effect (SMSI). The reduction temperature influences mainly the content of active components, crystal size, and the abilityfor adsorbing and activating H 2 . The developed pore structure and large specific surface area of the KIT-6 support favored the Ni dispersion. The RT450 catalyst, which was prepared in H 2 atmosphere at 450 • C, has the best HDO performance. Ethyl acetate can be completely transformed and maintain 96.8% ethane selectivity and 3.2% methane selectivity at 300 • C. The calculated apparent activation energies of the prepared catalysts increased in the following order: RT550 > RT400 > RT500 > RT450.
