The Efficiency of Producing Biodiesel from Used Cooking Oil by
Precipitating Blood Cockles Shell Waste with a CaO Catalyst.
4th International Conference Eco-Innovation in Science, Engineering, and Technology.
Abstract
Bio-based waste materials perform an essential duty as valuable sources of
components that can be effectively utilized as active phases in the synthesis
of CaO catalysts for the generation of biodiesel. The abundance of shell Blood
cockles is considerable. Additionally, Indonesia has a stockpile of used
cooking oil. The utilized cooking oil has a notable concentration of fatty acids,
presenting the potential for conversion into biodiesel. The technology of
converting leftover cooking oil into biodiesel through transesterification has
undergone significant advancements. An accelerator is necessary to boost the
biodiesel yield to attain a sufficiently high yield. The CaO catalyst was selected
due to its ability to expedite and boost biodiesel output. This study evaluated
the blood clam shell's potential as a transesterification catalyst for used
cooking oil. This study used temperature and concentration change variables
for transesterification, with a settle variable of 60 minutes. The
concentrations of the variables are 3 N, 4 N, 5 N, 6 N, and 7 N, whereas the
temperatures are 45 ⁰C, 50 ⁰C, 55 ⁰C, 60 ⁰C, and 65 ⁰C. With varying
transesterification times of 60 minutes, transesterification temperatures of
60°C and 65°C, and catalyst concentrations of 6N and 7N, the research
findings indicate that utilizing this catalyst can boost biodiesel yield with
conversion yields of 85%, 88%, and 95%. This demonstrates that
temperature can also promote improving biodiesel production and that using
catalysts can boost the conversion of biodiesel to over 90% or more.
