Design and development of laboratory scale microwave assisted glycerolysis reactor to perform glycerolysis reaction for waste cooking oil (WCO)

, 2019
Biodiesel from waste cooking oil is a renewable fuel that can be derived from waste cooking oil through transesterification process. However, it is learned that most of the waste cooking oil contains high level of FFA which may lead to saponification ...

Lipase catalyzed glycerolysis of ratfish liver oil at stirred tank basket reactor: A kinetic approach

, 2018
The kinetics of the lipase (Novozym 435) catalyzed glycerolysis of ratfish liver oil has been studied at pilot plant scale. A model derived from a generalized Michaelis–Menten mechanism was developed to describe the rates of disappearance of ...

Microwave-irradiated zinc chloride catalyzed glycerolysis of high free fatty acid vegetable oil

, 2015
Biodiesel, a popular alternative to fossil-based diesel, can be produced from cheap and sustainable sources like waste cooking oil. However, waste cooking oil, with its inherent FFA content, requires a pre-treatment step to lower the FFA content, making ...

Application of a novel solid superbase catalyst of Na2O/molecular sieve analogs (HND-63) in synthesis of plant-based monoglyceride and its catalytic mechanism

Grain & Oil Science and Technology
Monoglyceride (MAG) is a widely used nonionic surfactant. In this work, an economic and green solid superbase HND-63 was utilized to synthesize monoglyceride, and the independent variables were examined to achieve the highest MAG content.
