In this study, a heterogeneous basic catalyst was synthesized from a catalyst composite
material (CCM) of coffee husk ash and char mixture (A/C) impregnated with KNO3 and …

Biodiesel has gained wide acceptance as an alternative energy source despite its high cost
of production. This study investigated the possibility of lowering the cost of biodiesel …

The current research was aimed to corroborate as well as compare the feasible applicability
of waste banana peel and empty fruit bunch (EFB) in synthesising high‐performing …

In this study, alkali and bifunctional catalysts were synthesized for waste frying oil methyl
ester (WFOME) synthesis. Coffee husk (CH) and CH blended with Eragrostis tef straw …

This study explores the enhancement of biodiesel production via microwave-and ultrasonic-
assisted transesterification, comparing their efficiencies against conventional methods using …

In this work, we discuss the valorization of biomass waste-derived orange peel ash (OPA) by
exploring its applicability as a heterogeneous catalyst in aqueous aldol reactions and …

Potassium hydroxide (KOH) immobilized on rapana shells-based anorthite (ART) and waste
coal fly ash (CFA) was investigated as a catalyst (KOH/ART and KOH/CFA) for sunflower oil …

In this work, the beads and powder potassium hydroxide (KOH) and potassium carbonate
(K2CO3) supported on alumina oxide (Al2O3) were successfully prepared via incipient …

In facilitating a shift from the traditional fossil fuel into biofuels, a heterogeneous bio-based
catalyst was utilized to produce biodiesel. This bifunctional catalyst was produced using a …

Fossil fuels are non-renewable resources and their excessive usage may cause extinction.
To overcome the problem of possible extinction of this energy source, the production of …
