The catalytic thermal degradation of polypropylene over aluminum containing ordered mesoporous MCM-41 and SBA-15 based materials was studied in a semi-batch reactor. Heavier molecules degraded to lighter hydrocarbons in the presence of catalysts and they gave high ethylene selectivity among the gaseous products. Additionally, butane selectivity increased with the use of catalysts. SBA-type catalysts showed higher selectivity to lighter hydrocarbons (<C-14). C-7 selectivity among the liquid products was high when aluminum isopropoxide was used in the synthesis of catalysts and C-18 selectivity increased significantly when aluminum nitrate was used in the synthesis of MCM-type catalysts.

Thermal degradation of poly(propylene oxide) and polyepichlorohydrin by direct pyrolysis mass spectrometry
Uyar, T; Hacaloğlu, Jale (2002-09-01)
The thermal degradation of poly(propylene oxide), (PPO) and polyepichlorohydrin, (PECH) were studied with the use of direct pyrolysis mass spectrometry. The effects of heating rate and dissociative ionization on fragmentation pattern have also been investigated. It has been determined that PPO degrades via a random cleavage mechanism, the labile C-O bond scissions being preferred, An analogous degradation mechanism can be proposed for PECH. Yet, the elimination of side chains, evolution of HCl and the loss ...
Thermal degradation of polystyrene composites. Part I. The effect of brominated polyepoxy and antimony oxide
Kaya, Hatice; Hacaloğlu, Jale (2014-01-01)
Thermal degradation of polystyrene (PS) involving brominated polyepoxy (BA) and antimony oxide (PS/BE/Sb2O3) was studied systematically via direct pyrolysis mass spectrometry. Thermal decomposition of brominated polyepoxy was started by loss of end groups. The relative yields of high mass thermal degradation products of PS and the product distribution of brominated polyepoxy and antimony oxide were changed noticeably during the pyrolysis of PS/BE/Sb2O3 composite. Its thermal decomposition was initiated by t...
Thermal degradation of polysiloxane and polyetherester containing benzoxazine moieties in the main chain
Bagherifam, Shahla; Kışkan, Barış; Aydogan, Binnur; Yagci, Yusuf; Hacaloğlu, Jale (2011-01-01)
In this study investigation of thermal characteristics of polysiloxane and polyetherester containing benzoxazine moieties in the main chain was performed via pyrolysis mass spectrometry. Pyrolysis mass spectrometry analyses revealed that the thermal stability and the extent of cross-linking enhanced when the benzoxazine moieties were separated by thermally more stable units such as siloxanes. However, when the siloxane chain units were long, possibility of polybenzoxazine growth decreased significantly and ...
Catalytic oxidation of nitrogen containing compounds for nitrogen determination
Karakaş, Gürkan (2019-02-15)
The high temperature catalytic oxidation (HTCO) performance of Al2O3 supported Pt, Cu, Cu-Ce and Fe catalysts were systematically studied with a perspective of selective oxidation of nitrogenous compounds to nitric oxide for quantitative determination of bound nitrogen. The catalyst samples were prepared via impregnation and characterized by XRD and BET. In addition, temperature programmed reaction experiments with acetonitrile and oxygen were conducted to evaluate the catalytic activity and selectivity tow...
Catalytic combustion of ethyl acetate
GÜRMEN ÖZÇELİK, TUĞBA; Atalay, Sueheyda; Alpay, Erden (Elsevier BV, 2007-01-01)
The catalytic combustion of ethyl acetate over prepared metal oxide catalysts was investigated. CeO, Co2O3, Mn2O3, Cr2O3, and CeO-Co2O3 catalysts were prepared on monolith supports and they were tested. Before conducting the catalyst experiments, we searched for the homogeneous gas phase combustion reaction of ethylacetate. According to the homogeneous phase experimental results, 45% of ethylacetate was converted at the maximum reactor temperature tested (350 degrees C). All the prepared catalysts were test...
