Abstract

Studi penggunaan katalis tembaga molybdenum oksida berpenyangga silica (CuMoO₃/SiO₂) untuk oksidasi parsial metana menjadi methanol dan formaldehida telah dilakukan. Preparasi katalis dilakukan dengan metode impregnasi. Hasil identifikasi dengan XRD menunjukkan bahwa komponen katalis terdiri dari senyawa MoO_3,Cu₂Odan SiO₂. Uji kinerja katalis dilangsungkan dalam reaktor pipa lurus berunggun tetap, beroperasi pada temperature 400, 450 dan 500 ⁰C dan tekanan 1 atm. Produk reaksi dianalisis menggunakan gas kromatografi buatan Shimadzu dengan kolom mole sieve 5A dan porapak Q. Konversi metana tertinggi diperoleh 34,1% menggunakan katalis dengan rasio Cu: Mo 1: 3, temperatur reaksi 400 ⁰C. Perolehan methanol tertinggi 3,4 % dan perolehan formaldehida tertinggi 7,3%.
