Abstract

Minyak nabati murni (Pure Plant Oil / PPO) dari kelapa sawit dapat digunakan sebagai subtitusi bahan bakar solar pada mesin diesel. PPO dapat digunakan dengan mencampurkannya dengan solar, sehingga mengurangi penggunaan bahan bakar fosil yang tidak ramah lingkungan. Akan tetapi, bahan bakar campuran PPO juga memiliki sisi negatif seperti Specific Fuel Consumption (SFC) yang tinggi, viskositas tinggi, nilai kalor yang rendah, dan emisi NOx yang cenderung sedikit lebih tinggi. Dalam studi ini berbagai campuran PPO dan solar diuji di PLTD. Hasilnya menunjukkan bahwa PPO sebaiknya digunakan dengan campuran solar dan proses pre-heating dilakukan sebelum masuk ke mesin. Penggunaan PPO juga teruji sebagai bahan bakar yang ramah lingkungan, kandungan sulfur yang rendah, serta menghasilkan emisi gas rumah kaca yang rendah. Agar PPO dapat digunakan pada mesin diesel, maka perlu beberapa perubahan seperti modifikasi mesin seperti pre-heating PPO, modifikasi sistem injektor, dual fuelling, dan blending PPO dengan solar. Kata kunci : biofuel, PPO, kelapa sawit, PLTD, performa mesin diesel

Abstract

The influence of solvent was examined in the single- and two-stageliquefaction of Tanito Harum coal with FeNi supported oil carbon black(FeNi/KB) and a synthetic pyrite. FeNi/KB catalyst provide a high oi l yield inthe single-stage liquefaction when tetralin or 1methylnapthalene wasused, while pyrite (FeS2) gave a low oil yield in the liquefaction with 1-methylnapthalene although it produced a high enough oil yield in theliquefaction with tetralin. The single-stake liquefaction of coal gave extremelylow oil yields under the solvent free conditions for all catalysts examined. Inthe liquefaction of coal with solvent, the difference of oil yield producedbetween single-stage and two stage is small. However, the conversion of H--donor solvent after liquefaction was much lower than that of single-stageliquefaction. In the free-solvent liquefaction coal, two-stage liquefactionproduced much higher oil yield than single-stage.Kata kunci: solvent, catalyst, single-stage coal liquefaction, two-stage coalLiquefaction

Abstract

DME has characteristics similar to LPG so that the storage and handling are not so different from LPG. DME could be used as a solvent that can extract typical types of rubber/polymer material. The aims and objectives of this study are to determine the effect of DME/LPG (100/0, 80/20, 50/50, 30/70, 20/80) on the stability of the DME/LPG mixture on the stove and also to observe the effect on several rubber materials/polymers on stove accessories. The study reveals that the usage of a DME/LPG mixture between 20/80 - 30/70 does not require a replacement of any substitute materials but only requires minor modifications to the stove. However, at a higher DME composition, the use of the fuel needs to replace the seal that is resistant to DME. It occurs due to the change of the gas composition when it is used.
