Protolytic Ring-Opening Cracking of Methylcyclohexane over Hierarchical High-Silica USY Zeolite: A Haag-Dessau Cracking
نویسندگان
چکیده
To reveal the influence of acid sites with different spatial locations USY zeolite micro-/mesoporous structures and Si/Al ratio, catalytic cracking methylcyclohexane on zeolites is employed to study synergism effects porous (“active region”) in hierarchical zeolites. The results showed that have increased numbers accessibly strong Brønsted greatly enhanced diffusion ability due pore-structure, resulting mainly monomolecular protolytic scission reactions less bimolecular hydrogen transfer. isomerization reaction from intramolecular transalkylation isomerics are intermediates reaction. occurs high-silica USY-zeolites follows Haag-Dessau cracking.

Hierarchical Macro-meso-microporous ZSM-5 Zeolite Hollow Fibers With Highly Efficient Catalytic Cracking Capability
Zeolite fibers have attracted growing interest for a range of new applications because of their structural particularity while maintaining the intrinsic performances of the building blocks of zeolites. The fabrication of uniform zeolite fibers with tunable hierarchical porosity and further exploration of their catalytic potential are of great importance. Here, we present a versatile and facile ...
متن کاملSelective formation of propylene by hexane cracking over MCM-68 zeolite catalyst.
Dealumination of MCM-68 zeolite with MSE topology enhanced the selectivity to propylene (45-50%) and durability to coke formation during hexane cracking, regardless of the reaction temperature, which is attributed to the control of the position and density of acid sites originating from the framework Al atoms.
متن کاملCracking a hierarchical chaotic image encryption algorithm based on permutation
In year 2000, an efficient hierarchical chaotic image encryption (HCIE) algorithm was proposed, which divides a plain-image of size M×N with T possible value levels into K blocks of the same size and then operates position permutation on two levels: intra-block and inter-block. As a typical position permutation-only encryption algorithm, it has received intensive attention. The present paper an...
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...
متن کاملShape of a cracking whip.
The crack of a whip is produced by a shock wave created by the supersonic motion of the tip of the whip in the air. A simple dynamical model for the propagation and acceleration of waves in the motion of whips is presented. The respective contributions of tension, tapering, and boundary conditions in the acceleration of an initial impulse are studied theoretically and numerically.
