Abstract

A hydroconversion catalytic process of Indonesian petroleum residue from Plaju(UP IV) refinery plant was investigated. A series of liquefaction tests using a 1liter stirred batch autoclave reactor under reference condition e.i.: initial hydrogenpressure of 12 MPa and 2.0 of atomic ratio of sulfur to iron were conducted. Theinfluence of the temperature of 430,450,470oC and the reaction time of 30,60,90minute was used and compare the yield structure of each run. It was found thatthe oil yield and gases CO, CO2 and hydrocarbon yield increased significantly bythe increasing of the temperature reaction and holding time. While, the liquidbottom yield had a tendency to decrease which reversely to the oil yield. It alsoappeared that hydrogen consumption would tend to increase with increasing oilyield, leading to the more efficiently use of gaseous hydrogen. As a result, thehydroconversion catalytic process could be applied to upgrade petroleum residuewhich indicated by increasing oil yield in mild condition.Kata Kunci: hidrokonversi katalitik, residu minyak bumi

Abstract

This study presents the investigation on the reactivity of vacuum oil residue(VOR) as solvent in Banko coal liquefaction, so called ?Co-processing?. Processsolvent derived from BSU tests is used as reference solvent in this study. Theliquefaction tests are carried out using a gas-flow type autoclave (5L) with 200gcoal (daf), 400g of coal-derived solvent (b.p.300-420 oC), 1.0-3.0 wt% daf as Feof catalyst and elemental sulfur (S/Fe atomic ratio of 2.0) at 14.7MPa, 450oC for60min under a constant gas flow of H2-0.5%H2S. The study suggests that VORas solvent is much more reactive than process solvent under the same condition.Therefore the co-processing gives higher oil yield than coal liquefaction usingprocess solvent derived from BSU tests. It also produces lower CLB, CO+CO2and hydrocarbons yields. This indicates that there is a synergism effect betweenthe VOR as a donor solvent and the coal. The molecular structure of VOR at thefirst time was decomposed into molecular fragments. These fragments were thenattached onto the coal?s structure and lead to decompose the structure of thecoal. It was also found that co-processing consumed less hydrogen gas thanreference liquefaction process. In short, this finding obtained in this study cangive promising sight for implementing the coal liquefaction plant in Indonesia at acommercial scale.Kata kunci: vacuum oil residue, Banko, liquefaction, co-processing reactive,synergism effect
