Cement wastes as transesterification catalysts for the production of biodiesel from Karanja oil

Biodiesel Synthesis From Waste Cooking Oil Using a Variety of Waste Marble as Heterogeneous Catalysts

“…The results of IR spectra of CaO are similar to those of calcined egg shells powder and calcined C. brunneus shell (Bharathiraja et al, 2018;Mazaheri et al, 2017). Similarly, the peaks at 1420-1500 cm -1 and 3650 cm -1 for CO 3 -2 and OH stretching, respectively, were also confirmed from IR spectra of calcined C. brunneus shell and calcined cement wastes (Mazaheri et al, 2017;Kumar et al, 2018).…”

A review on non-edible oil as a potential feedstock for biodiesel: physicochemical properties and production technologies

“…Some of these properties are viscosity (mm 2 s À1 ), density (kg m À3 ), cloud points ( C), power points ( C), cetane number (MJ kg À1 ), acid value (mg KOH per g oil), sulphur content and oxidation stability. 33,[140][141][142] Biodiesel produces from edible and non-edible oil must mitigate the standard specication of biodiesel set by ASTM 6571, EN 14214. Table 7 presents physicochemical properties of non-edible biodiesel and standard specication of biodiesel for ASTM 6571 and EN 14214.…”

Research advancement and commercialization of microalgae edible oil: a review

“…4 Most research uses farm-level algae risk models to develop production models that fit the cultivation systems or production scenarios, and cost estimation occurs through process simulators such as Aspen plus. 101,102 To verify the commercial feasibility of microalgae biomass products, life-cycle assessment and resource assessment are also indispensable. The current results of TEA are quite different, mainly due to the different growth structure, production path, financial input and productivity assumptions in each model.…”
