Perengkahan Residu Minyak Bumi PPSDM Migas Dengan Metode Aquathermolysis

Abstract
Heavy oil is generally composed of hydrocarbons as the main component and several types of impurity compounds in small amounts.Cracking with aquathermolysis method is one way to reduce the physical properties of petroleum residues. Aquathermolysis utilizes water as a solvent at temperatures above the boiling point of water with the help of active materials as cracking agents. This research examines the effect of NiO/Fe3O4 catalyst which is synthesized by coprecipitation method in aquathermolysis reaction of Oil and Gas PPSDM Residue.The aquathermolysis reaction was carried out in a stainless steel batch reactor system.The results shows that the catalyst which is obtained is trevorite crystal Fe1,7Ni1,43O4 and has shown having catalytic activity in the aquathermolysis reaction of Oil and Gas PPSDM Residue. The aquathermolysis reaction to the uncatalyzed residue increased the aliphatic content and decreased the aromatic content in the residue, while the reaction with the catalyst decreased the aliphatic and aromatic hydrocarbon content.Both reactions increase the levels of heteroorganic compounds. If  the ratio of the catalyst to the reactants getting weighter,cause the viscosity of the reaction products getting lower. When compared with the initial residue, the decrease in the viscosity of the reaction product without catalyst, catalyst/reactant = 0.002 ; and catalyst/reactant = 0.01 3.00%, 3.33%, and 6.00%, respectively. The greater the ratio of residual
