Waste Cooking Oil Gasification with Pressure Stoves

Kerosene gasification with pressure stoves have been applied to people such mawar stoves. use of waste cooking oil as fuel for pressure stoves are still in the early stages of research. Waste cooking oil viscosity higher than that of kerosene, this is a problem in the use of the mawar stove, since mawar stove used of oil pipeline smaller than 2.5 mm. The research was carried out by utilizing the mawar stove by using waste cooking oil fuel.

The Effect of H-USY Catalyst in Catalytic Cracking of Waste Cooking Oil to Produce Biofuel

The crisis in petroleum is caused by the diminishing supply of petroleum resources from nature. This phenomenon encourages researchers to continue to look for processes and methods to produce energy from other resources. One of these ways is to produce energy that can be utilized from waste, including converting waste cooking oil into biofuel. This method not only could provide a source of renewable energy, but also help resolve the issue of household waste. The process used to produce biofuel from waste cooking oil is by catalytic cracking, where waste cooking oil after pretreatment is converted into biofuel in the flow reactor with H-USY catalyst. In this research, the reaction temperatures used are 400 °C, 450 °C, 500 °C and 550 °C and reaction times are 30, 45 and 60 minutes with the mass ratio of the amount of waste cooking oil to the amount of catalyst used is 40:1 (w/w).
