چکیده

The increasing significance of biomass in attaining ultimate sustainability a multitude vectors demands deeper understanding its underlying components. pyrolytic breakdown cellulose, major component, has been subject intense research since the 1950 s, and despite significant carried out published thus far, kinetics cellulose degradation continue to be source debate. Herein, this work investigates using Advanced Kinetics Technology Solutions (AKTS) software. Kinetic parameters were computed three methods, Friedman’s differential iso-conversional, FWO ASTM-E698. results indicate Ea values 40–181, 68–166, 152.1 kJ/mol, Friedman’s, ASTM-E698 respectively. Based on obtained via iso-conversional method, predictions under isothermal, non-isothermal stepwise heating profiles are presented. revealed that rapid takes place up 80% conversion, temperature 350–400 °C is required efficiently achieve this, while temperatures 650 higher needed 100% conversion less than 2 h, isothermal conditions.

Isothermal and Non-isothermal Methods

a comparison was made between the experimental non-isothermal a vs. t curves and those calculated on the basis of a previous isothermal study. It was observed that for low heating rates, when the "thermal lag" is negligible, the dynamic measurements are in good agreement with the isothermal ones. Furthermore, for process (I), two mathematical methods proposed for the interpretation of the non-i...

Thermal behavior and decomposition kinetics of rifampicin polymorphs under isothermal and non-isothermal conditions

The thermal behavior of two polymorphic forms of rifampicin was studied by DSC and TG/DTG. The thermoanalytical results clearly showed the differences between the two crystalline forms. Polymorph I was the most thermally stable form, the DSC curve showed no fusion for this species and the thermal decomposition process occurred around 245 °C. The DSC curve of polymorph II showed two consecutive ...

patterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment

although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...

Microstructure and strength modelling of Al–Cu–Mg alloys during non-isothermal treatments Part 1 – Controlled heating and cooling

A model is developed to predict the precipitation kinetics and strengthening in Al–Cu–Mg alloys during non-isothermal treatments consisting of controlled heating and cooling. The prediction of the precipitation kinetics is based on the Kampmann and Wagner model. The precipitation strengthening by the shearable Cu–Mg co-clusters is modelled on the basis of the modulus strengthening mechanism and...

Formation kinetics of hydroxymethylfurfural, lactulose and furosine in milk heated under isothermal and non-isothermal conditions.

A detailed kinetic study of hydroxymethylfurfural, lactulose and furosine formation was performed upon heating milk at temperatures between 90 degrees C and 140 degrees C. In case of prolonged heating, formation kinetics could be described by a fractional conversion model. Considering only the first phase of the model, kinetics could be simplified to a pseudo-zero order model. A first assessmen...
