An experimental study was performed on an adsorption refrigeration unit powered by a solar energy and equipped with three different types of activated carbon (1: Coconut, 2: Palm seeds, 3: Charcoal). In this Study design, factorial analysis and optimization of a prototype unit were described. The activated carbon coupled with methanol was used as an adsorbent-adsorbate pairs. Experimental tests...

Digital technology in the form of a drying oven is used for process sample biomass fuel. There are 2 types used, namely Coconut Shell and Acacia tree branches. The as fuel oven. This study aims to analyze change temperature, humidity heat with various mass variations coconut shells acacia Mass 1000 gr, 1500 2000 2500 3500 gr. research begins by burning from first variation last variation.

A horizontal drum kiln is a traditional method widely used in Southeast Asian countries for producing biochar. An understanding of temperature conditions the and its influence on biochar properties crucial identifying suitable applications. In this study, four agricultural residues (corncob, coconut husk, shell, rice straw) were production. The turned into within 100–200 min, depending their st...

Activated carbons with micropores for adsorption and filtration of the volatile constituents of mainstream cigarette smoke, together with mesopores for enhanced mass transport were prepared by a novel route. Treatment of coconut shell or other lignocellulosic precursors with aqueous NaOH, followed by thorough washing, charring and steam activation produced carbons with enhanced adsorption chara...
