The Role of Intraparticle Diffusion in Kinetic Model Discrimination: Proof of Concept Testing for Methanol Dehydration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...

CLASSIFICATION OF SOLID PARTICLE CRUSHING EQUIPMENT

open access: yes
Our raw materials that reach production are mostly hard and large in size. This causes us a lot of inconvenience in production, and at the same time, it also causes the quality of our products to decrease. Therefore, after the arrival of our raw materials, they are first washed, crushed and similar operations are carried out and washed to the ...

Elastoplastic constitutive model for granular materials considering meso-particle damage

open access: yesYantu gongcheng xuebao
Establishing a constitutive model for granular materials that accounts for particle shape and breakage mechanisms has been crucial for calculating the mechanical stability of earth-rock dam projects. Initially, through the triaxial compression tests, the

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Single Particle Crushing under Slow Rate of Loading

open access: yes, 2010
application/pdfAn experimental study of the single particle crushing under a slow (constant) rate of loading was carried out by using specimens shaped into sphere made of quartz glass, borosilicate glass and six kinds of minerals. The diameters of sphere

Impact of Chitosan Incorporation on PBAT Composite: Thermal, Viscoelastic, Mechanical, and Morphological Properties

open access: yesJournal of Applied Polymer Science, EarlyView.
The abstract explains the impact of various concentrations of chitosan on PBAT composite. Indeed, the composite is produced at increasing concentrations of chitosan (10%, 20%, and 30%). The decrease in the tensile strength with increased conc. of chitosan was recorded. Furthermore, the same impact was recorded for TGA analysis.

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.
