Optimization of the preparation of activated carbon from palm kernel shell for methane adsorption using Taguchi orthogonal array design

Abstract

The preparation of activated carbon from palm kernel shell for methane adsorption was studied. Taguchi orthogonal array design was employed to optimize the preparation of activated carbon. The statistical results show that the optimized conditions are the impregnation ratio of 0.55, the activation temperature of 900 o C and the activation time of 150 min. The impregnation ratio has the most influence on methane adsorption based on S/N ratio analysis. The mathematical model was developed using regression analysis as a function of independent variables. The results of experiment using optimum conditions fall within the predicted value obtained from the developed model. Activated carbon prepared at optimum conditions which have the highest BET surface area of 1,548.0 m 2 /g and the total pore volume of 1.0 cm 3 /g recorded the highest methane uptake compared to other conditions. The equilibrium data of the adsorption characteristic fitted favourably to the Freundlich isotherm.

Analisis Proksimat Karbon Kulit Kemiri (Aleurites moluccana) dengan Variasi Suhu Karbonisasi

“…Karbon dapat didefinisikan sebagai amorf yang memiliki porositas dan luas permukaan yang tinggi [5], karena struktur berpori ini, karbon aktif banyak digunakan dalam berbagai aplikasi, seperti adsorben zat warna [6], adsorben logam berat dan gas [7], katalis, elektroda (baterai dan superkapasitor) [8]. Karbon dapat disintesis dari biomassa yang tersusun dari lignoselulose.…”

REVIEW: SINTESIS KARBON AKTIF DENGAN MENGGUNAKAN AKTIVASI KIMIA ZnCL2

“…Sementara pada variasi waktu karbonisasi antara 30 sampai 70 menit yang dilakukan oleh Bacaoui, dkk (2001), diperoleh bahwa waktu berpengaruh signifikan, dengan waktu optimum 68 menit (Bacaoui dkk., 2001). Akan tetapi, hasil berbeda diungkapkan oleh Syed-Hassan dan Zaini (2016), di mana variasi waktu karbonisasi (60-150 menit) merupakan variabel yang tidak berpengaruh signifikan terhadap luas permukaan, pada studi pembuatan karbon aktif dengan rancangan percobaan Taguchi dengan tingkat kepercayaan 95%. Hasil serupa juga diperoleh pada penelitian Loredo-Cancino, dkk (2013) di mana waktu tidak berpengaruh signifikan dalam optimasi luas permukaan karbon aktif.…”

Recent advances of ring opening of epoxidation of palm oil derived from oleic acid via in situ hydrolysis under moderate temperature

“…Vegetable oils are renewable, sustainable, and biodegradable sources of raw material, and the epoxidation of these oils can provide a greener, cleaner, and more affordable alternative to petroleum-based epoxidized resins. 5 In addition to the environmental benefits, epoxidation of vegetable oils also offers several advantages in terms of their material properties. 6 Vegetable oil-based epoxy resins can provide comparable or even superior performance to petroleum-based resins, and they can also offer benefits in terms of their processing costs, biodegradability, energy consumption, and safety.…”

“…Epoxidation of vegetable oils is becoming an increasingly popular alternative to petroleum‐based epoxidized resins. Vegetable oils are renewable, sustainable, and biodegradable sources of raw material, and the epoxidation of these oils can provide a greener, cleaner, and more affordable alternative to petroleum‐based epoxidized resins 5 . In addition to the environmental benefits, epoxidation of vegetable oils also offers several advantages in terms of their material properties 6 .…”
