The energy crisis and environmental pollution have recently fostered research on efficient
methods such as environmental catalysis to produce biofuel and to clean water …

An ever-increasing energy demand and environmental problems associated with
exhaustible fossil fuels have led to the search for an alternative renewable source of energy …

Due to food shortages and increasing fuel prices, scientists are trying to find suitable
feedstocks for biodiesel production that do not divert food products to bioenergy. Although …

Rising global prices, increasing energy demand, and increasing greenhouse gas have led
to the use of biodiesel fuel. Biodiesel fuel is a suitable alternative to diesel in diesel engines …

In this report, the utilization of mixed methanol–ethanol system for the production of
biodiesel from waste cooking oil (WCO) using enhanced eggshell-derived calcium oxide …

The present study aimed to optimize the process on the yield percentage of biodiesel from
Argemone mexicana oil using calcium oxide as catalyst derived from chicken eggshells. The …

This study investigated the transesterification of waste cooking oil using methanol and
modified wheat bran ash and CaO as the catalyst. Under a simple solid-state reaction …

Biodiesel is becoming an alternative renewable energy source as it is safe, biodegradable,
and eco-friendly. Biomass-based, heterogeneous CaO nanocatalyst, prepared using …

Researchers have shown considerable interest in finding a sustainable, low cost, and
readily available substitute for the commercial calcium oxide (CaO) catalyst. In this work, raw …

Most of the world's energy needs are met by oil, and many countries import a large portion of
their oil demand. This causes a very critical problem, such as energy dependence. On the …
