Application of Zeolitic Additives in the Fluid Catalytic Cracking (FCC)
Current article describes application of zeolites in fluid catalytic cracking (FCC). The use of several zeolitic additives for the production light olefins and reduction of pollutants is described. Application of zeolites as fluid catalytic cracking (FCC) catalysts and additives due to the presence of active acid sites in the zeolite framework increase the formation of desired cracking product...
متن کاملAgglutination of single catalyst particles during fluid catalytic cracking as observed by X-ray nanotomography.
Metal accumulation at the catalyst particle surface plays a role in particle agglutination during fluid catalytic cracking.
متن کاملIron ochre – a pre-catalyst for the cracking of methane
BACKGROUND Iron ochres are gelatinous sludges that can cause problems in terms of water management. In this work, the application of iron ochre obtained from a river has been applied to catalytically crack methane - another potential waste product - into two useful products, hydrogen and a magnetic carbon-containing composite. RESULTS The powder X-ray diffraction (XRD) pattern of the iron och...

متن کاملHigh-Resolution Single-Molecule Fluorescence Imaging of Zeolite Aggregates within Real-Life Fluid Catalytic Cracking Particles**
Fluid catalytic cracking (FCC) is a major process in oil refineries to produce gasoline and base chemicals from crude oil fractions. The spatial distribution and acidity of zeolite aggregates embedded within the 50-150 μm-sized FCC spheres heavily influence their catalytic performance. Single-molecule fluorescence-based imaging methods, namely nanometer accuracy by stochastic chemical reactions...
