The structure of the graft copolymers was confirmed by Fourier Transform InfraRed (FT-IR) spectroscopy and ThermoGravimetric Analysis (TGA). The inhibition effects of produced graft copolymers (as new kinetic hydrate inhibitors) and polyvinyl alcohol were investigated on gas hydrate formation with a methane-propane mixture which forms the structure II of the hydrate. In all experiments, the initial pressure was adjusted at 23 bar, temperature at 2 ˚C, and the stirring rate at 400 rpm. All of the tested materials reduce hydrate formation rate and their inhibition strength was PVA-g-AAM1 PVA > PVA-g-AAM1 بود. نتیجه­ های آزمایشگاهی و سینتیک تشکیل هیدرات نشان دادند که کوپلیمر پیوندی PVA-g-AAM1 سرعت متوسط رشد هیدرات را نسبت به تشکیل هیدرات با آب خالص، تا 11 درصد کاهش می‏ دهد. همچنین کوپلیمر پیوندی PVA-g-AAM2 این سرعت را تا 29 درصدکاهش داده که نشان دهنده پتانسیل مناسب تر آن به عنوان یک بازدارنده جدید سینتیکی سازگار با محیط زیست، است.}, keywords_fa = {بسپارش,کوپلیمر پیوندی,هیدرات گازی,بازدارنده سینتیکی}, url = {https://www.nsmsi.ir/article_28241.html}, eprint = {https://www.nsmsi.ir/article_28241_c16cf9a4c702ec5669d15ce54fcb688b.pdf} }
