بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی بیان شده اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...
15 صفحه اولKinetic Study of the Decomposition of Cellulose to 5-Hydroxymethylfurfural in Ionic Liquid
The kinetics of cellulose decomposition in ionic liquid was investigated using microcrystalline cellulose as a raw material. Curve fitting of cellulose degradation kinetic data was carried out by MATLAB. Experimental results demonstrated that the cellulose decomposition rate constant, k1, was less than the constant for glucose decomposition to 5-hydroxymethylfurfural (5HMF), k2, in the ionic li...
متن کاملZeolite Catalyzed Hydrolysis in Aqueous and Ionic Liquid Media
Hydrolysis of ethyl acetate and starch in water and of cellulose in an ionic liquid by using HY and HZSM-5 solid acid catalysts are compared. In water, HZSM-5 is more active than HY. This trend is reversed in ionic liquid. Reactivity differences are explained based on interactions between solvent and catalyst acid site local environments, which depend on zeolite channel structure and Si/Al rati...

متن کاملEnhanced Hydrolysis of Cellulose in Ionic Liquid Using Mesoporous ZSM-5.
Mesoporous ZSM-5 prepared by alkaline treatment was demonstrated as an efficient catalyst for the cellulose hydrolysis in ionic liquid (IL), affording a high yield of reducing sugar. It was demonstrated that mesoporous ZSM-5 (SiO₂/Al₂O₃ = 38) had 76.2% cellulose conversion and 49.6% yield of total reducing sugar (TRS). In comparison, the conventional ZSM-5 had a mere 41.3% cellulose conversion ...
