Abstract

Dengan makin terkurasnya minyak-minyak "ringan" dan "mudah" perhatian makin diarahkan pada minyak-minyak berat dansulit. Slah satu masalah dalam pengembangan potensi minyak berat ialah tiadanya metode baku yang khusus dirancang dan teruji untuk minyak berat.

Abstract

Spesifikasi bahan bakar minyak di Indonesia ditetapkan dalam Peraturan Direktur Jenderal Minyak dan Gas Bumi No. 002/P/DM/migas/1979 yang ditetapkan pada tanggal 25 Mei 1979. Peraturan ini kemudian mengalami perubahan, yaitu dengan Peraturan Direktur Jenderal Migas No. 004/P/DM/Migas/1979 yang membaharui ketentuan-ketentuan spesifikasi khususnya mengenai bahan bakar penerbangan avtur.

Abstract

The survey of gas oil production and impact of more stringent specification on the catalyst performance of ASEAN refineries conducted in 1996 revealed that a total feedstock of 5,673 MBPSD are processed into 1,131 MBPSD gas oil. This consist of the following product distribution: straight-run gas oil 85.44%, thermal cracked gas oil 2.52% cat. Cracked gas oil 3.50% and hydrocracked gas oil 8.54% on total gas oil products. About 50% of this total gas oil is processed in hydrotreating processes to improve the performanceof diesel oil.This paper reviews the production of gas oil components in ASEAN and the effect of the changing gas oil quality requirement on hydrotreating catalyst performance.

Abstract

Recent economic development in Indonesia, as in other ASEAN countrie, has resulted in improved prosperity as reflected by the significant increase in the numbers of motor vehicles, particulary in big cities. This growth in car population and traffic is unfortunately accompanied by increase in not only of the country’s energy consumption but also increased air pollution. Almost 70% of atmospheric pollution in big cities is reported to be contributed by motor vehicles.In view of this situation, the Government of Indonesia has launched the “Blue Sky program” and introduced unleaded gasoline. Indonesia manufacturing industries have responded also by designing “nationalautomobiles” to be fabricated in Indonesia, and to run with unleaded gasoline. Some of these vehicles will be equipped with catalytic converters to reduce exhaust gas emissions.In support of this program, LEMIGAS R/D Center for Oil and Gas Technology is developingits-own catalytic converters that can be fitted into these cars. The work carried out toward this end is outlined briefly in this paper
