Abstract

To obtain ethanol purity >99.5%, an adsorption method using Lampung Natural Zeolite (ZAL) is needed. In order to be used as a zeolite adsorbent, activation must be carried out using UV light lamp irradiation germicidal lamp 254 nm, blacklight lamp 360 nm and insect lamp 546 nm. The results of the BET characteristic test showed that the surface area of ??the non-treated zeolite was 41,331 m2/g, the germicidal lamp was 41,158 m2/g, the black light lamp was 40,399 m2/g and the insect lamp was 38,796 m2/g. The largest total pore volume was obtained from UV germicidal lamp activated zeolite 0.0690 cc/gram and the average pore size was found in insect lamp activated zeolite 35.57. After the activation of the zeolite, pellets were formed using a binder from wheat flour with a composition of 35% by weight of zeolite, then the zeolite was calcined to remove the binder that was still attached and opened the pores that were closed by the binder. The results obtained were dehydrated ethanol to increase purity using zeolite activated by UV germicidal lamp 98.69% v/v for 45 minutes, blacklight and insect lamp 98.69% v/v for 55 minutes.

Abstract

Palm oil shells are solid waste from the palm oil processing industry. In 1 ton of palm oil produces 6.5% shell waste. Solid waste can be converted into fuel as a substitute for oil, namely bio-briquettes as an alternative fuel through a combustion process with less air. This study aims to determine the effect of time variations on the quality and yield of bio-briquettes produced using a combined pretreatment method of densification (with additional binder) and torrefaction at a temperature of 275 oC and time variations of 30, 45, 60, 75 and 90 minutes. Torrefaction is a new method in the briquetting process where this method takes place at low temperatures. The results showed that the longer the torrefaction time, in general, the value of water content, ash content, volatile matter content, fixed carbon value and burning time also increased. However, this is inversely proportional to the yield value of the resulting product, so the best quality is obtained in 75 minutes with a moisture content of 0.86%, ash content 2.38%, volatile matter content 18.23%, fixed carbon value 78.51 %, product yield is 36.3165% and calorific value is 5964 Kcal/kg.
