Supporting staff, PSE research group

            Looking calm and low profile, and also enjoys helping students in conducting research both in the equipment design and processes technology. At first glance did not show that men who daily called as Pak Taryo, is a figure who mastered all the technical aspects in the PSE research group

Research Title:

Integrated Pyrolysis – Tar Decomposition Process Using Wood Waste and Low Grade Iron Ore

 

Research Outline:

Among all biomass conversion processes, pyrolysis is one of the promising. As well-known, pyrolysis produce char as main product, tar and gases as by-products containing carbon and energy. In the pyrolysis process, tar Char is main product used as agent of reduction. Tar is an undesirable material caused blockage, corrosion of the downstream equipment, tar aerosol formation and carcinogenic. Therefore , steps should be taken to remove or decompose tar into gas fuel ( syngas ) , H2 and other compounds. There are three ways to remove, it is the physic, catalytic and non - catalytic , but in terms of economic and technical,  catalytic processes is the most promising. Several materials were studied by a number of researchers  as potential catalyst such as Ni, Pt, Rh, and Pd but deactivation of catalyst due to carbon deposition is main problem. The use of low-grade iron ore as the catalyst can be used as an alternative to overcome these problems because the carbon deposits formed can be utilized in the iron - making process as a reduction agent replacing coke.

This study will integrate the process of pyrolysis - tar decomposition using low grade iron ore as catalyst. In addition to the decomposed or reduced tar, low-grade iron ore expected better quality for using directly in iron-making industry.

Research Title:

Catalytic Cracking Bio-oil of Palms Oil Empty Fruit Bunches Into Liquid Bio-Fuel

 

Research Outline:

The need of energy is increasing and oil reserves as a primary energy resources is decreasing that is the reason why seeking alternative energy source is inevitable. Biomass especially palms oil empty fruit bunches (PEFB) which are abundant in Indonesia can be processed into bio-oil by pyrolysis process. The potential for direct substitution of bio-oil for petroleum  may be limited due to the high viscosity, high oxygen content and corrosiveness. Consequently, upgrading of the bio-oil before use is desirable to give liquid product that can be used  in a wider variety of applications. Furthermore, upgrading process, which is  neccessary to improve the quality of bio-oil through reduction of oxygenates normally involves process such as catalytic cracking. One of the main challenges in catalytic cracking of bio-oil is undesired formation and retention of carbonaceous deposits, called coke. Coke causes catalyst deactivation through poisoning catalyst acid site and pore blockage. In order to minimize catalytic coke formation,  Bio-oil derived from PEFB was upgraded through catalytic cracking using series tubular reactor under atmospheric pressure with zeolite mesoporous catalyst. The objective of this research is to study the effect of catalytic cracking temperature and thickness of bed catalyst to selectivity of aromatic hydrocarbon especially gasoline,  to study kinetic  catalytic cracking reaction of bio-oil and to study exergy analysis method.  The catalytic cracking system consist of tube reactor, a liquid feed system, a liquid feed pump, furnace, stove, a gas of LPG system, a condenser and a cooler water pump. The process was conducted in continue with volumetric rate of bio-oil 10 ml/minute. Compound composition of bio-oil and product were measured using gas chromatography-mass spectroscopy (GC-MS).
