Biodiesel emerges as a viable option to replace fossil fuels, but the traditional process for production of biodiesel requires large energy expenditure, since transesterification has slow conversion due immiscibility alcohol and oil. On other hand, with hydrodynamic cavitation method, shorter time can be achieved high yield; however, there are few studies related this method. Therefore, objecti...

When ultrasound waves pass through a medium, a series of compression and rarefaction waves on the molecules of the medium are produced. This enforces a sinusoidal acoustic pre...

Cavitation remains a popular field of scientific research due to the generated effects and wide range possible applications. At same time, despite active development technologies for treatment liquid materials by cavitation action, equipment used initiation action has not fundamentally changed. In this regard, main direction efficiency technological processes based on impact should be search wa...

A novel approach is developed for desulphurization of fuels or organics without use of catalyst. In this process, organic and aqueous phases are mixed in a predefined manner under ambient conditions and passed through a cavitating device. Vapor cavities formed in the cavitating device are then collapsed which generate (in-situ) oxidizing species which react with the sulphur moiety resulting in ...
