Experimental Study on Spent FCC Catalysts for the Catalytic Cracking Process of Waste Tires

Abstract

Research on the synergistic high-value reuse of waste tires and used catalysts in spent fluid catalytic cracking (FCC) catalysts was carried out in this study to address the serious ecological and environmental problems caused by waste tires and spent FCC catalysts. The experiment, in which a spent FCC catalyst was applied to the catalytic cracking of waste tires, fully utilized the residual activity of the spent FCC catalyst and was compared with a waste tire pyrolysis experiment. The comparative experimental results indicated that the spent FCC catalyst could improve the cracking efficiency of waste tires, increase the output of light oil in pyrolysis products, and improve the quality of pyrolysis oil. It could also be used for the conversion of sulfur compounds during cracking. The content of 2-methyl-1-propylene in catalytic cracking gas was found to be up to 65.59%, so a new method for producing high-value chemical raw materials by the catalytic cracking of waste tires with spent FCC catalysts is proposed.

“…They analyze both the advantages and disadvantages for both methods of co-firing fuels. Wang et al [22] study the synergistic high-value reuse of waste tires and used catalysts in spent fluid catalytic cracking (FCC) catalysts to address the serious ecological and environmental problems caused by waste tires and spent FCC catalysts. Their results show that the content of 2-methyl-1-propylene in catalytic cracking gas is found to be up to 65.59%.…”

Influence of Binder Type on the Mechanical Properties of SIFCON Composites Made With Waste Steel Fibers

“…Bu atıklar doğal ortamda çözünemediğinden çevreye ve sağlığımıza zarar vermekle beraber ekonomiye de geri kazandırılamamaktadır [12]. Atık miktarınınki artış ile birlikte ekolojiye verilen zararın artışı atık lastiklerin artık global bir probleme dönüştüğünü göstermektedir [13]. Halen ömrünü tamamlamış lastiklerin yüksek kalorileri nedeni ile alternatif yakıtlar şeklinde, lastiklerin kaplanmasında, asfalt üretiminde değerlendirilmektedir [14][15][16].…”

A Novel Method to Investigate the Activity Tests of Fresh FCC Catalysts: An Experimental and Prediction Process from Lab Scale to Commercial Scale

“…Fluid catalytic cracking (FCC) technology has been (and is still) one of the most important conversion processes in petroleum refinery for converting heavy fractions to more valuable fuels, such as gasoline, diesel, liquefied petroleum gas (LPG), olefinic gases, and some other products [1][2][3]. Due to the high flexibility of operation for different types of feedstocks, such as biomass-derived feedstocks, FCC technology has been long-lasting, and witnessed several stages of developments and revolutions for catalyst, feedstock, process technology, and reactor design [4][5][6]. In other words, the wider diversity of feedstocks, fluctuation of product market, and environmental emissions control have continuously proposed a number of challenges for fresh FCC catalysts, reaction conditions, and even production distribution [7][8][9][10].…”
