Exhausted coffee residue (ECR) and husk (CH) are potential feedstock for energy production through thermochemical biochemical conversion processes. Kinetic study of ECR CH is essential the design optimization different In this study, four iso-conversional methods were employed in estimation activation (EA) pre-exponential factor (A). The used includes Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-S...

The catalytic pyrolysis of Chlorella vulgaris, high-density polyethylene (Pure HDPE) and, their binary mixtures were conducted to analyse the kinetic and thermodynamic performances from 10 100 K/min. parameters computed by substituting experimental ANN predicted data into these iso-conversional equations plotting linear plots. Among all models, Flynn-Wall-Ozawa (FWO) model gave best prediction ...

Herein, cotton stalk biomass was initially characterized to understand its physicochemical properties as a raw material for biochar production. Furthermore, thermal analysis conducted using thermogravimetric (TGA), and the results were further utilized evaluate stalk's kinetic behavior under decomposition in an inert environment. Advanced kinetics technology solutions (AKTS) software first time...

Abstract Non-isothermal reaction mechanism and kinetic analysis for the synthesis of monoclinic lithium zirconate (m-Li 2 ZrO 3 ) were investigated by processing TG-DTA, along with XRD, DLS, HRTEM. For this purpose, solid-state Li CO was carried out TG-DTA at different heating rates (10, 20, 30 °C/min) from room temperature to 1100 °C. The thermal data used calculate parameters two types isocon...

In this study, we show that adding halloysite nanotubes (HNT) to carbon black (CB)-packed acrylic rubber (ACM) composites improves their thermal properties. The thermo-oxidative stability, and dynamic mechanical properties of ACM (filled simply with 70 phr CB) hybrid comprising a fixed amount CB (60 phr) variable (2, 4, 6, 8, 10 were investigated. As evidenced by the oxidation induction time an...

One of the decisive factors in obtaining the desired properties in coatings is their complete curing, which necessitates the study of kinetics of curing. In recent years, many studies have been conducted on the use of polyhedral oligomeric silsesquioxane (POSS) in coatings. Creating functional groups on POSS and using it in formulation can create new or improve the properties of coatings. I...

Abstract The effects of particle size on the apparent kinetics carbothermal reduction process phosphate rock were studied by non-isothermal thermogravimetric analyses. Phosphate various was reacted with coke and silica under high purity argon atmosphere. kinetic model parameters reaction different sizes derived combination model-free (Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, Tang, Starink) m...

Abstract In the context of processing, utilization and disposal polylactic acid composites, pyrolysis is a promising technique that addresses this complex synergy. work, kinetics thermodynamic parameters rice husks/clay fiber-reinforced PLA composites were investigated using Kissinger–Akahira–Sunose (KAS) Ozawa–Flynn–Wall (OFW) at multiple heating rates (16, 25 34 °C min −1 ). composites’ follo...

Abstract Rice husk is abundantly available biomass in Indonesia and it can be a potential source of high-value energy source. In the present work, pyrolysis rice was subjected to various temperature used as method produce bio-oil. The decomposition profile examined at different heating rates (10, 20, 30, 40°C/min) using thermogravimetric analysis (TGA) method. kinetics were evaluated three kine...

Many agro-industrial companies grow amaranth for the subsequent production of oil, flour, cereals, flakes, and bran. After grain is extracted, waste in form inflorescences remains, which can be used to obtain useful new products. This work investigated use pyrolysis recycle inflorescence wastes (AIW). Thermochemical conversion experiments an inert medium were carried out a laboratory setup at 5...
