Abstract

Sintesis Fischer-Tropsch merupakan reaksi polimerisasi yang menghasilkan berbagai produk seperti parafin, olefin, alkohol dan aldehida. Tujuan dari penelitian ini adalah mengetahui kinerja katalis bimetal Fe dan Co dengan support HZSM-5 untuk sintesis Fischer-Tropsch. Penelitian ini terdiri dari dua tahap. Tahap pertama diawali dengan membuat katalis HZSM-5 berukuran mesopori yaitu dengan proses desilikasi, kemudian diimpregnasi dengan bimetal Fe dan Co sehingga didapatkan katalis Fe-Co/HZSM-5. Metode impregnasi yang digunakan adalah incipient wetness impregnation. Pada proses impregnasi dilakukan variasi berupa rasio logam Fe dengan Co (1:9, 2:8, 3:7). Katalis Fe-Co/HZSM-5 yang tebentuk dilakukan uji karakteristik. Uji karakteristik meliputi BET, XRD, FTIR, EDX dan SEM-EDX. Tahap kedua adalah reaksi katalitik (proses Fischer-Tropsch) dari katalis Fe-Co/HZSM-5 yang telah terbentuk. Proses Fischer-Tropsch dilakukan dalam reaktor fixed bed, dengan suhu operasi 225, 250 dan 275oC dilakukan selama 120 jam dalam sekali running. Selanjutnya dilakukan analisa GC-MS untuk mengetahui komposisi produk dari hasil reaksi katalitik (proses Fischer- Tropsch). Pada ratio 2:8 dengan suhu 2250C mampu meghasilkan produk kerosin dan diesel, serta beberapa senyawa turunan benzene.

Fischer-Tropsch synthesis is a polymerization reaction that produces various products such as paraffin, olefins, alcohols, and aldehydes. The purpose of this study was to determine the performance of Fe and Co bimetal catalysts with the support of HZSM-5 for Fischer-Tropsch synthesis. This study consists of two stages. The first stage was started by making mesopore-sized HZSM-5 catalyst, namely by the desilication process, then impregnated with Fe and Co bimetallic so that Fe-Co / HZSM-5 catalyst was obtained. The impregnation method used is the incipient wetness impregnation. In the impregnation process variations are made in the ratio of Fe to Co (1: 9, 2: 8, 3: 7). The formed Fe-Co / HZSM-5 catalyst was tested for characteristics. Characteristic tests include BET, XRD, FTIR, EDX, and SEM-EDX. The second stage is the catalytic reaction (Fischer-Tropsch process) from the formed Fe-Co / HZSM-5 catalyst. The Fischer-Tropsch process is carried out in a fixed bed reactor, with operating temperatures of 225, 250 and 275oC carried out for 120 hours in one run. GC-MS analysis was then carried out to determine the composition of the product from the results of the catalytic reaction (Fischer-Tropsch process). At a ratio of 2: 8 with a temperature of 2250C it can produce kerosene and diesel products, as well as several benzene derivative compounds.
