Indonesia's limited fossil energy reserves trigger the emergence of the fuel crisis problem in Indonesia. To overcome the problems of fuel scarcity several ways can be done, among others, by mixing fuel and bioethanol. The use of bioethanol is one of the ... see more

Technological developments in diesel engines require improvements to the fuel injection system to meet the criteria for economical, high-power and efficient combustion and meet environmental regulatory standards. One method that has a lot of interest is c... see more

Growing demand for hydrogen promotes the research devoted to the development of new catalysts for hydrocarbons processing in absence of H2 or at its low concentration. In the present work, it was shown that during the conversion of straight-run gasoline o... see more

The influence of bioethanol content and parameters of the cavitation field on the quality indicators of motor gasolines: volatility and octane number is studied. Studying the effect of bioethanol and cavitation treatment of bioethanol-gasoline mixture wil... see more

Penelitian ini bertujuan untuk mengetahui potensi triptamin sebagai antioksidan untuk gasoline serta pengaruhnya terhadap sifat fisik gasoline. Metode yang digunakan yaitu menguji aktivitas antioksidan melalui uji periode induksi dan massa gum, sedangkan ... see more

Activity test and regeneration of NiMo/active natural zeolite catalyst for hydrocracking of waste plastic fraction of polyprophylene (PP) type have been carried out. The catalysts was prepared by loading Mo followed by Ni Metals onto the natural zeolite (... see more

Optimation of time and catalyst/feed ratio in catalytic cracking of waste plastics fraction to gasoline fraction using Cr/Natural Zeolite catalyst has been studied.The natural zeolite was calcined by using nitrogen gas at 500 oC for 5 hours. The chromium ... see more
