To realize the energy recovery of wheat straw, pyrolysis behavior straw was studied at three heating rates (10, 20, and 30 K/min) based on thermogravimetric analysis (TG–DTG). Kinetics thermodynamics were analyzed using Flynn–Wall–Ozawa (FWO) Kissinger–Akahira–Sunose (KAS) model-free methods, reaction mechanism determined Coats–Redfern (CR) model-fitting method. The results show that there are ...

Abstract The most common polymeric nanocomposites are constituted of organically-modified clays. Generally, these organic modifiers based on quaternary ammonium salts. These systems have as disadvantage the low thermal resistance its under processing. Ionic liquids (IL) with different molecular structures can be used modifier in lamellar clays-based nanocomposites, being promising not only to i...

In this study, RuO2-embedded PES membrane was prepared and it used for protein separation. The antifouling properties of the fabricated composite membranes were also investigated using bovine serum albumin (BSA) as solution. mean roughness increased proportionally by introducing RuO2 particles. porosity higher than that pristine membrane. On other hand, has smaller average pore size after addit...

In connection to present energy demand and waste management crisis in Pakistan, refuse-derived fuel (RDF) is gaining importance as a potential co-fuel for existing coal fired power plants. This research focuses on the co-combustion of low-quality local with RDF mean reduce environmental issues terms strategy. The combustion characteristics kinetics coal, RDF, their blends were experimentally in...

In the present work, kinetic and thermodynamic analysis of ficus wood was carried out using thermogravimetric (TGA). Thermal degradation has been evaluated under dynamic conditions from 373 K to 1173 at heating rates 5, 10, 20, 50 K.min?1. The performed isoconversional methods (Friedman (FR), Flynn-Wall-Ozawa (FWO) Vyazovkin (VYA)) integral master-plots method estimate triplets. data were used ...

To further understand the effect of chrome tanning on the thermal stability of leather, the thermal shrinkage behaviors of native and chrome-tanned collagen fibers were studied by differential scanning calorimetry (DSC) using isoconversional and multivariate non-linear regression (Multivar-NLR) methods. The activation energies of the shrinkage processes were evaluated by both the differential (...

Abstract Biocopolymers based on vanillin/fufurylamine–biobenzoxazine (V-fa) and epoxide castor oil (ECO), a bioepoxy, were prepared for application as dental fiber-reinforced composite post. The mechanical thermal properties of the V-fa/ECO biocopolymers assessed with regard to influence ECO content. addition at an amount 20% by weight into poly(V-fa) preserved stiffness, glass transition tempe...

This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...

In view of the global objective carbon neutrality, using natural biomaterials to prepare bio-based polyurethane (BPU) is a significant means reducing our heavy dependence on fossil fuels. If utilization these increase, appropriate treatment methods after they reach end their life cycle are challenge that must be addressed in advance. present study, thermogravimetric (TG) experiments were conduc...
