    Konversi Cangkang Sawit menjadi Bio-oil Menggunakan Katalis Ni.Mo/Lempung Cengar
    (2013-07-16) Sandra, Anisa; Bahri Syaiful; Sunarno
    At this time the world experienced an energy crisis. This is due to the high dependence on fossil fuels, petroleum. Petroleum has the non-renewable nature and amount of production decline each year. Therefore, the innovation required to produce an alternative energy,that is bio-oil from biomass such as palm shells. Indonesia, has a vast plantation sector of palm oil. Bio-oil can be produced from palm shell waste through pyrolysis process using a catalyst Ni.Mo / Clay cengar. This study aimed to determine the effect of catalyst ratio Ni.Mo / Clay cengar the bio-oil produced. This pyrolysis used palm shell 50 grams, silinap 500 ml and the weight ratio of catalyst 0, 0.5, 1.5, 2.5, and 3.5% w / w biomass. Bio-oil produced at the optimum catalyst ratio of 0.5% w / w of biomass with yield 40.0%. Results of bio-oil analyzed physics, density 0.9625 g / ml, viscosity 8.99 cSt, flash point 48 ° C, acid value 45.71 g NaOH/ g sample, and heating value 51.47 MJ / kg. GCMS analysis produced chemicals that bio-oil that can be processed further processed into alternative energy sources other than petroleum.
