Abstract

Currently, much attention is devoted to produce bioethanol based on lignocellulosic materials for alternativefuels. Production of bioethanol from lignocellulosic generates black liquor as a waste during the pretreatmentprocess. The black liquor has a potential to produce platform chemicals. Conversion of black liquor into platformchemicals was carried out by hydrothermal liquefaction by involving water as reaction medium at 200275 C.Through the hydrothermal process combined with water at high temperature, catalytic role could be taken over bysodium sulfate. Increase in temperature up to 275C, activity of water combined with sodium sulfate also increasedin decomposition of block chemicals containing in the black liquor. The black liquor was converted into oxygenatedcompounds, such asphenol, propylene oxide, butyrolactone, and quaiacol. The chemicals were recovered as23, 16, 11 and 8 mol%, respectively.

Abstract

Pyrolysis of cacao pod husks as one of agricultural crop residue took place in a fixed bed type of pyrolyzer under atmospheric pressure at 500oC. The process was studied by varying methods and temperature of feeding.The effect of N2 flow rate as carrier gas was also investigated. These effects influenced yield of product after pyrolysis especially on the char. Char as the main product of pyrolysis was recovered as 70 C mol% with one step feeding at 25oC under 20 ml/min of N2. Pyrolysis of cacao pod husk also produced bio-oil that consisted of several chemical compounds such as aliphatic and cyclic ketones, carboxylic acids, furans, aldehydes, alcohols, phenols and heterocyclic aromatics.

Abstract

Catalytic cracking of vegetable oil for the production of bio-hydrocarbons had been developed. In this study, the catalytic cracking of Refined-Bleach-Deodorized Palm Oil (RBDPO) had carried out over Fluid Catalytic Cracking Unit (FCCU) equilibrium catalyst in a micro activity test reactor at 510°C under various catalyst to oil (CTO) ratio of 1.20 - 2.01 g/g. The catalytic cracking of RBDPO had produced the organic liquid product (OLP) containing bio-hydrocarbon, water, gas, and coke on the catalyst converted to CO2 during the catalyst regeneration process. The increase in CTO ratio from 1.20 to 2.01, OLP yield decreased from 80.48% to 70.12%. The OLP was separated into gasoline, light cycle oil (LCO), and heavy cycle oil (HCO) based on boiling point difference by a simulated distillation gas chromatography (SimDis GC). High gasoline fraction as 31.56% was produced at CTO of 2.01 g/g. The gasoline fraction contained olefins, aromatics, paraffin, iso-paraffins, and a small amount of naphthenes and oxygenates. The presence of chemicals in the gasoline fraction influenced the research octane number (RON) of the fuel.Keyword: bio-hydrocarbon; catalytic cracking; micro activity test reactor; RBDPO
