“…Catalyst reusability in biodiesel production is one of the most important criteria in industry 44. Reusability was tested with 1 g of CaO120 catalyst in 100 g of WCO with a reaction time of 1 h and oil/methanol ratio of 1/9.…”

The utilization of waste cooking oil (WCO) and bleached palm oil (BPO) for the production of biodiesel in the presence of hydrothermally treated calcium oxide (CaO) derived from waste chicken eggshells was investigated. Waste chicken eggshells were calcined at 850 °C and then hydrothermally treated at 120 and 140 °C to produce two sets of CaO catalysts. Hydrothermal treatment of the catalysts resulted in a decrease of the crystallite size from 47 to 30 and 28 nm at temperatures of 120 and 140 °C. The catalytic performance of the CaO catalysts was evaluated with WCO and BPO, respectively. WCO gave biodiesel yields of 82.7 and 83.1 % for CaO catalysts aged at 120 and 140 °C respectively. BPO gave 79.4 and 79.6 % yields, respectively, for the same set of catalysts.

“…It can also be deduced that the leaching of calcium oxide content in the catalyst was the main reason for the sudden drop in conversion. (Kostić et al, 2016, Satya Lakshmi et al, 2020. Most samples were within the ASTM range for standard diesel from the result of the blended diesel samples.…”

“…The statistical second order central composite (CCD) design was used in planning of regeneration experiments using Design-Expert software (demo version). In addition, temperature and time were selected as process factors in the experimental plan; as seen in Table 1, positive levels of factors were determined from fresh catalyst preparation conditions and the negative levels were determined from similar catalyst regeneration studies cited in the literature [18,19].…”

Reusability of two heterogeneous catalysts in ultrasound (US) assisted biodiesel production was investigated in comparison to each other. An ultrasound (US) generator (200 W, 20 kHz) equipped with a horn type probe (19 mm) was used. Regeneration experiments were planned according to second order central composite design (CCD) method. After the eighth use of the catalysts, biodiesel yield decreased from 99.1% to 90.4% for calcined calcite (CaO) and from 98.8% to 89.8% for calcined dolomite (CaO.MgO). Furthermore, regeneration of spent catalysts by calcination was investigated; optimum temperature and time were found as 750 °C and 90 min, lower than fresh catalyst preparation conditions. The regenerated catalysts were reused in a second process cycle; biodiesel yield was calculated as 97.2% for CaO and 96.5% for CaO.MgO. Finally, the process showed that calcination is an energetically favorable regeneration process of spent catalysts.
