Increasing Bioethanol Content From Pineapple Skin Using Catalyst Waste as Adsorben Results from Cracking Process in PT. PERTAMINA RU III
Bioethanol is an ethanol produced from fermentation that has passed the distillation results. One of the raw materials that can be used to make bioethanol is pineapple skin. Sugar content contained in pineapple skin is 11.40%. From the fermentation process using bread yeast the resulting bioethanol content is 4,5%. To increase the bioethanol produced, other methods besides distillation are used, namely the adsorption process. The adsorbent used in this study is Pertamina RU III waste cracked. The use of this type of adsorbent is as a substitute for natural zeolite adsorbents which are more relatively expensive than Pertamina RU III wasted cracked that is easily to get and more economical. The purpose of this research is to find out how to increase bioethanol using this type of adsorbent. The result of this research is increasing contents of 65,855% with physically activated.
