Title

Second Generation of Biodiesel Production from Indonesian Jatropha Oil by Continuous Reactive Distillation Process Arief Budiman; Ratna D Kusumaningtyas; Sutijan Sutijan; Rochmadi Rochmadi; Suryo Purwono

The batch process of biodiesel production deals with problems related to the labor and separation cost since it is slow, entailing several separation steps, labor intensive, and not suitable for a very large-scale production. Therefore, a second generation process technology for biodiesel should be developed. In this work, a continuous transesterification using reactive distillation was proposed. The goal was to bring in a more efficient reactor system by combining chemical reactions and separation simultaneously in one unit. In this work, a laboratory-scale Reactive Distillation was applied for the biodiesel synthesis from the Indonesian refined jatropha oil in the presence of NaOH catalyst. The experimental investigation demonstrated the effects of the temperature, catalyst loading, and molar ratio of the reactants. The best result was achieved on the process conducted at the reaction temperature of 65 ºC with molar ratio of methanol to triglycerides of 10:1 and catalyst loading of 0.75% w/ w oil. The reaction conversion was 94.83% and methyl ester content of the product was 99.27%. The fuel characteristic of biodiesel agreed with the Indonesian national standard and ASTM specification.

Dynamic Cycling State of Nonadiabatic Catalytic Combustion of Propylene Suryo Purwono
ASEAN Journal of Chemical Engineering Vol 6, No 1 (2006)
Publisher : Department of Chemical Engineering, Universitas Gadjah Mada

An experimental study of nonadiabatic fixed-bed reactor for controlling propylene gas was made under flow reversal operation. Temperature measurements were made within the catalyst and packing beds. The influence of the operating parameters on the shape of temperature profiles, conversion, and heat removal were studied. The experiments showed that the maximum measured reactor temperature and heat removal were rather insensitive to changes in cycle duration and sensitive to feed flow rate and reactant concentration. The simulation results for the variation of concentration, flow rate, and cycle time showed the experimentally observed behavior Further simulations showed that runaway can occur when concentration was high.

CO Oxidation over Metal Oxide CatalystSupported by Indonesian Natural Zeolite Suryo Purwono
ASEAN Journal of Chemical Engineering Vol 2, No 1 (2002)
Publisher : Department of Chemical Engineering, Universitas Gadjah Mada

The objectives of this study are to attempt to develop catalysts and to find the operating conditions under which combustible waste gases concentrations in the exhaust gases can be eventually reduced to satisfy air pollution standards. The results shows that using impregnation method, nickel and vanadium metals, as active components of the catalyst, can be dispersed on the natural zeolite as catalyst support. The reaction rate measurements of catalytic oxidation of CO was done in the temperature range between 300 and 550°C using a differential micro-reactor. The catalysts used for this experiment were vanadium pentoxide and nickel oxide on activated natural zeolite. To avoid fluidization, the reactant gases were flowed downward. The results show that the reaction rate depends strongly on the bed temperature and feed concentration and is not controlled by bulk phase mass transfer and pore diffusion.

The need for energy, especially the petroleum-based one, is steadily increasing along with population growth and technological advancement. Meanwhile, oil exploitation from oil reservoirs using primary and secondary techniques can only obtain about 30%-50 % out of the original oil in place. Enhanced Oil Recovery (EOR) is a method for increasing oil recovery from a reservoir by injecting materials that are not found in the reservoir, such as surfactant, polymer, etc. This research aims to develop a mathematical model representing two-phase flow through porous media in the EOR process. This model was extended from mass balance and fluid flow in porous media equations. The reliability of the model was then validated by water flooding and polymer flooding experiment. A porous media, constituted by a silica sand pack, was saturated with 2 % brine and sequentially flooded with HPAM polymer solution at various concentrations (5,000-15,000 ppm). The volume of the oil coming out from the media at any time intervals was measured. Validation of the model was carried out by optimizing the model parameters to obtain the best curve-fitting on the plot of the percentage of cumulative recovered oil against time. The results showed that the proposed mathematical model was reliable enough to express both water and polymer-flooding processes.
