Polyols in polyurethane production is of great importance. The future will increase the production of polyols from renewable sources. The result of the reduction of fossil fuels will be important in the use of renewable resources. Especially important alt... see more

Amide and ester type polyols were synthesized from rapeseed, sunflower and castor oils, and two types of ethanolamine (diethanolamine and triethanolamine) at different molar ratio. Poly(urethane amides) and polyester urethanes based on the synthesized pol... see more

Biodiesel is produced from esterification and transesterification reactions of various vegetable oils such as coconut oil, palm oil, seed oil, soybean oil, etc. Waste cooking oil has the potential as a raw material for making biodiesel due to its abundant... see more

The exhaustion of natural resources has increased petroleum prices and the environmental impact of oil has stimulated the search for an alternative source of energy such as biodiesel. Waste cooking oil is a potential replacement for vegetable oils in the ... see more

Flexible polyurethane foams is the most produced foam compared to other types of polyurethane foams. The raw material for polyurethane foams is usually derived from petroleum polyols. The availability of petroleum which is getting thinner needs to be soug... see more

The paper provides detailed information involved in the numerical simulation of transesterification of waste vegetable oil (WVO).  The main objective of this work is to perform mixing study based on large eddy simulation particle image Velocimetry (... see more

Transesterification of waste vegetable oil is one of the promising partial substitutes for fossil fuels. The degradation characteristics of waste vegetable oil using supercritical alcohols (ethanol and methanol) have been studied in this research. The ele... see more

This review paper will conduct mainly about oil-water emulsion treatment using biopolymer-based ultrafiltration membrane. Oil emulsion wastewater mainly use ultrafiltration process for its treatment due to its continuable process, high efficiency and low ... see more

The world's oil reserves are running low, which makes the government also implement a mandatory B30 policy starting in early 2020. With this policy, it is necessary to develop energy by utilizing renewable energy such as vegetable oil that can be converte... see more
