Production of green fuel by catalytic cracking of waste cooking oil using different metal modified zeolite catalysts at different reaction temperatures
Minyak sayuran digunakan sebagai bahan mentah dan ditukar kepada minyak kerana ketumpatan tenaga yang tinggi, sifat cair dan ketersediaannya sebagai sumber yang boleh diperbaharui. Walau bagaimanapun, minyak masak sisa juga mendapat perhatian yang ketara kerana ia tidak menyebabkan persaingan makanan vs bahan api dan lebih murah. Keretakan katalitik adalah salah satu cara yang paling berkesan untuk memproses minyak masak sisa dengan memecahkan kehadiran pemangkin. Projek ini membincangkan kesan pelbagai pemangkin zeolit, kesan pemangkin zeolit diubahsuai logam dan juga kesan suhu tindak balas yang berlainan pada prestasi retak pemangkin minyak masak sisa. Minyak masak sisa retak pada suhu tindak balas 250, 300 dan 350 ° C dan halaju ruang berat 1 hr-1 untuk menghasilkan bahan api hijau dalam reaktor katil tetap. Nitrogen dengan kadar aliran kira-kira 200 ml / min digunakan sebagai gas pembawa. Tindak balas dilakukan terhadap ZSM-5, zeolit Y dan mordernite zeolite pemangkin dan diubahsuai dengan logam Fe, Cu dan Ni untuk mengkaji pengaruh pemangkin pada retak pemangkin. Produk yang diperolehi dianalisis dengan kromatografi gas dan mereka diklasifikasikan kepada pelbagai titik minyak, minyak tanah dan diesel. Hasil maksimum produk yang dikehendaki (petrol, minyak tanah, diesel) diperoleh dengan Ni / ZSM-5 dengan suhu reaksi 350 ° C.

Vegetable oil is used as a feedstock and is converted to fuel due to its high energy density, liquid nature and its availability as a renewable source. Nevertheless, waste cooking oil has also gained substantial attention because it does not cause food vs fuel competition and is cheaper. Catalytic cracking is one of the most effective ways to process waste cooking oil by cracking in the presence of catalyst. This project discusses the effect of various zeolite catalysts, the effect of metal modified zeolite catalyst and also the effect of different reaction temperatures on the performance of catalytic cracking of waste cooking oil. Waste cooking oil was cracked at reaction temperatures of 250, 300 and 350°C and weight hourly space velocity of 1 hr-1 to produce green fuel in a fixed bed reactor. Nitrogen with flow rate of about 200 ml/min was used as a carrier gas. The reaction was performed over ZSM-5, zeolite Y and mordernite zeolite catalysts and modified with Fe, Cu and Ni metals in order to study the influence of catalysts on catalytic cracking. The products obtained were analyzed by gas chromatography and they were classified into gasoline, kerosene and diesel boiling point range. The maximum yield of lighter hydrocarbons (gasoline, kerosene and diesel) was obtained when catalytic cracking was performed using Ni/ZSM-5 at reaction temperature of 350°C.
