Catalytic Cracking of Waste Cooking Oil to Alkane-Based Hydrocarbon Over Activated Carbon Supported La and Ce Oxides
The increasing global demand for fuel, along with pressing environmental regulations and concerns, and the need for energy security, all point to the biofuel industry seeing rapid growth in the near future. The objective of this study was to study the performance of a series of activated carbon (AC) supported La and Ce oxide catalysts in the catalytic cracking of waste cooking oil into alkane-based hydrocarbon. Coconut-shell activated carbon was loaded with various amounts of lanthanum and cerium were prepared via wet impregnation. The catalytic cracking activity was evaluated in a fixed bed reactor under N2 flow at 450 °C and a weight hourly space velocity of 8 h−1 at 60 min. The physical and chemical properties of the prepared catalysts were characterized by BET, SEM–EDX, XRD, TPD-NH3/CO2, FTIR, and TGA. The results indicated that 5 wt% La/AC performed superiorly with a liquid product of 87.03% which composed of 99.09% hydrocarbons, that were mostly alkane (79.89%) with n-(C15 + C17) 66% selectivity (66.13%).
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
