Development of bifunctional catalyst for the single-step synthesis of dimethyl ether
Şener, Mehmetali İlker; Sezgi, Naime Aslı; Department of Chemical Engineering (2019)
Depletion of fossil fuels, global warming concerns and increasing CO2 emissions necessitated the utilization of syngas in the production of alternative fuels over the last few years. Dimethyl ether (DME) is considered as promising diesel substitute or LPG additive due to its high cetane number and good burning properties. The single-step DME synthesis method, which involves consecutive methanol formation and methanol dehydration reactions, enables the production of DME directly from the syngas. Despite the ...
Tek basamakta birincil alkollerin seçici yükseltgenmetepkimeleri için tekrar kullanılabilir polimer sentezi
Öztürk, Perihan; Akdağ, Akın (null; 2015-08-23)
2,2,6,6-tetrametilpiperidinokzil (TEMPO) radikali alkol yükseltgenme tepkimelerinde ikincil yükseltgen olarak kul-lanılmaktadır [1]. Bu radikalin yükseltgen olarak aktifleşebilmesi için birincil yükseltgen olarak elektron kabul eden bir yapı gerekmektedir [2]. Önceki çalışmalarımızda N-Halamin bağları içeren hidantoin içeren polimerler TEMPO için klor kaynağı olarak kullanılmıştı [3]. Hidantoin bileşiğininin yapısındaki amit ve imit bağları halojenleri kararlı bir şekilde tutabilmekte ve gerektiğinde diğer ...
Investigating the methane production efficiency of single- and two-phase anaerobic digestion and population dynamics of a second-phase anaerobic digestion
Koç, Engin; Bayramoğlu, Tuba Hande; Duran, Metin; Department of Environmental Engineering (2015)
The aim of this thesis study was to investigate the methane production efficiency of single-phase and two-phase anaerobic digestion (AD) in batch reactors and anaerobic sequencing batch reactor (ASBR). It was also aimed to monitor the population dynamics and change in the quantity of aceticlastic methane-producers of the second-phase of a two-phase ASBR. Two sets of batch reactors were conducted, namely, Batch Reactor Set-1 and Batch Reactor Set-2. The aim of Batch Reactor Set-1 was to investigate the effec...
A Scalable evolutionary algorithm for solving the one-dimensional bin packing problem on GPU using CUDA
Özcan, Şükrü Özer; Coşar, Ahmet; Sahillioğlu, Yusuf; Department of Computer Engineering (2015)
One-dimensional Bin Packing Problem (1DBPP) is a challenging NP-Hard combinatorial industrial engineering problem which is used to pack finite number of items into minimum number of fixed size bins. Different versions of 1DBPP can be faced in real life. Although the problems that have small number of items up to 20 can be solved with brute-force algorithms, large problem instances of the 1DBPP cannot be solved exactly due to its intractable nature. Therefore, heuristic approaches such as Genetic, Particle S...
Hybrid metaheuristic algorithms for single and multi-objective 2d bin packing problem
Beyaz, Muhammed; Coşar, Ahmet; Dökeroğlu, Tansel; Department of Computer Engineering (2015)
2D Bin packing problem (2DBPP) is an NP-hard combinatorial optimization problem. Objects with di erent width and length sizes are packed in order to minimize the number of unit-capacity bins according to an objective function. Single or multiobjective versions of this well-known industrial engineering problem can be faced frequently in real life situations. There have been several heuristics proposed for the solution of 2DBPP until now where it is not possible to find the exact solutions for large problem i...
