Abstract

Penelitian ini bertujuan untuk mempelajari studi kinetika dietil eter dari etanol dalam reaktor kontinyu menggunakan katalis granule Cr-Co/γ-Al₂O₃ melalui proses dehidrasi etanol. Variabel yang dipelajari yaitu pengaruh laju alir gas nitrogen dan suhu reaksi terhadap produksi dietil eter, konversi etanol, dan yield DEE. Proses produksi dietil eter dilakukan pada reaktor fixed bed dengan suhu reaksi 100°C, 125°C, 150°C, dan 200°C serta laju alir gas nitrogen sebesar 200 mL/menit, 400 mL/menit, dan 600 mL/menit. Produk yang terbentuk dianalisis menggunakan Gas Chromatography (GC) untuk mengetahui konsentrasi dietil eter yang dihasilkan. Hasil analisis GC menunjukkan bahwa konversi etanol terbesar, yaitu 93,12%, diperoleh pada laju alir gas nitrogen 200 mL/menit dan temperatur reaksi 150°C, sedangkan yield DEE tertinggi, yaitu 0,34%, diperoleh pada laju alir gas nitrogen 200 mL/menit dan temperatur reaksi 150°C. Yield dietil eter yang dihasilkan mengalami peningkatan pada suhu 100°C hingga 150°C. Studi kinetika melalui reaksi elementer menunjukkan bahwa reaksi merupakan reaksi orde dua dengan persamaan laju reaksi yang diperoleh, yaitu −rₐ = 18,485 Cₐ².

The research aimed to study the kinetics of diethyl ether synthesis from ethanol in a continuous reactor using a heterogeneous granular Cr-Co/γ-Al₂O₃ catalyst. The variables studied were the effects of nitrogen gas flow rate and reaction temperature on diethyl ether production, ethanol conversion, and diethyl ether yield. The DEE production process was carried out in a fixed-bed reactor at reaction temperatures of 100°C, 125°C, 150°C, and 200°C, with nitrogen gas flow rates of 200, 400, and 600 mL/min. The reaction products were then analyzed using Gas Chromatography (GC) to determine the concentration of DEE obtained. The GC results showed that the highest ethanol conversion was 93.12%, obtained at a nitrogen gas flow rate of 200 mL/min and a reaction temperature of 150°C. Meanwhile, the highest DEE yield was 0.34%, obtained at a nitrogen gas flow rate of 200 mL/min and a reaction temperature of 150°C. The DEE yield increased with increasing temperature from 100°C to 150°C. The kinetic study based on elementary reactions indicated that the reaction followed second-order kinetics, with the reaction rate equation obtained as −rₐ = 18.485 Cₐ².
