چکیده

فرضیه: در این پژوهش، فرایند پیرولیز زیست‌پلاستیک‌های تهیه‌شده از آمیخته‌ دو پروتئین حیوانی و
آرد کامل سیب‌زمینی مطالعه و سپس، رفتار سینتیکی و ترمودینامیکی آن‌ها طی فرایند پیرولیز بررسی شد. پروتئین‌های استفاده‌شده در این مطالعه شامل پروتئین آب پنیر و ژلاتین گاوی بود که از ضایعات‌ صنایع پرورش و فراورش محصولات دامی استخراج شدند.
روش‌ها: برای بررسی سینتیک تخریب گرمایی از روش‌های مختلف هم‌تبدیلی شامل Friedman،وFlynn-Wall-Ozawa،وKissinger-Akahira-Sunose و Starink استفاده شد. با هر یک از این مدل‌ها، پارامترهای سینتیکی تجزیه گرمایی برای نمونه‌های زیست‌پلاستیک شامل آمیخته‌های ‌ژلاتین گاوی-آرد کامل سیب‌زمینی (BG) و پروتئین آب پنیر- آرد کامل سیب‌زمینی (Wh) و نیز آرد کامل سیب‌زمینی به تنهایی (P) به‌عنوان شاهد محاسبه شد.
یافته‌ها: نتایج نشان داد، محدوده ‌انرژی فعال‌سازی بر اساس روش Friedman برای زیست‌پلاستیک‌های بر پایه آمیخته ‌BG، وWh و شاهد به ترتیب 60.15-214.65، 59.16-264.07وkJ/mol 50.38-216.68 تغییر کرده است. تخمین مدل واکنش با استفاده از روش Criado در دو شرایط تبدیل (a)، اول بین 0.1 تا 0.4 و دوم بین 0.1 تا 0.9، با هدف پوشش‌‌‌دهی رفتار زیست‌پلاستیک‌ها در دو شیوه فراورش و تولید انرژی ‌تجدیدپذیر نشان داد، در تمام زیست‌پلاستیک‌های بررسی‌شده، مدل Valensi و(D2) در شیوه فراورش و مدل Jander و(D3) در شیوه دوم بهترین برازش را بر اساس ضریب تبیین (R2) بین نمودارهای اصلی نظری و سرعت‌های کاهش‌یافته تجربی داشته‌اند. بررسی‌های ترمودینامیکی نمایانگر آن بود که بیشینه تغییرات آنتالپی مشاهده‌شده برای زیست‌پلاستیک‌های آمیخته‌ای ‌BG در تبدیل 0.5 برابر ~210kJ/mol و برای زیست‌پلاستیک‌های شاهد و آمیخته‌ای Wh در نسبت تبدیل 0.6 به ترتیب حدود 259 و  212kJ/mol بوده است. نتایج حاصل از این مطالعه ضمن تبیین رفتار گرمایی زیست‌پلاستیک‌های بر پایه آرد سیب‌زمینی در دماهای مختلف و روند تجزیه گرمایی، به تولید انرژی‌های تجدیدپذیر از ضایعات زیست‌پلاستیک‌ها کمک می‌کند.

چکیده [English]

Hypothesis: The pyrolysis process of bioplastics, prepared from a mixture of two animal proteins and whole potato flour, was studied and their kinetics and thermodynamic behavior during pyrolysis was investigated. The proteins used in this study included whey protein and bovine gelatin, which were extracted from the wastes of animal breeding and processing industries.
Methods: To study kinetics of thermal decomposition, various isoconversional methods including Friedman, Flynn-Wall-Ozawa, Kissinger-Akahira-Sunose, and Starink were used and the kinetic parameters of thermal decomposition were calculated for bioplastic samples consisting of bovine gelatin-whole potato flour (BG), whey protein-whole wheat flour (Wh) and whole potato flour (P) as control.
Findings: The results showed that the variation in activation energy calculated by the Friedman method for BG, Wh and control (P) bioplastic samples was 60.15-214.65 kJ/mol, 59.16-264.07 kJ/mol and 50.38-216.68 kJ/mol, respectively. Prediction of reaction model using Criado’s method in the conversion ranges of 0.1-0.4, and 0.1-0.9, in order to cover the behavior of the bioplastics in two modes of processing and producing renewable energy, respectively, showed that in all investigated bioplastics, Valensi model (D2) in processing mode and Jander model (D3) in the second mode had the best linearity coefficient (R2) between theoretical master plots and experimental reduced rates. Thermodynamic analysis showed that the maximum enthalpy change for BG was observed in the conversion of 0.5 and was equal to ~210 kJ/mol and for the control and Wh bioplastics were observed in the conversion of 0.6 and were equal to ~259 kJ/mol and ~212 kJ/mol, respectively. The results of this study not only determined the thermal behavior of potato-based bioplastics at different temperatures and the thermal decomposition process, but also helped to generate renewable energy from bioplastic wastes.
