In the present study mixtures of polymeric and cellulosic biomass materials were pyrolized in the presence of two different catalysts (sepiolite and aluminium bauxite) in various ratios by two different reactors; a rotary kiln reactor (RKR) and a fixed bed pyrolysis reactor (FBR). The results were compared to determine the effects of pyrol-ysis parameters such as catalysts, feedstock and reactor types on the energy content of the final products. First, the polymeric and cellulosic materials were mixed at certain ratios and thus the mixtures were prepared. Then, thermally activated catalysts were added to these mixtures. At the end of the experiments, certain properties such as higher heating value (HHV), the elemental concentrations, particle size and size surface areas of the end products (for solid and liquid phases) were calculated and analysed. The HHV of the liquid products from bauxite added mixture in RKR and FBR was 42.74 MJ/kg and 40.95 MJ/kg respectively. Besides the HHV of the oil products from sepiolite added mixture in RKR and FBR was 41.28 MJ/kg and 38.94 MJ/kg respectively. These values are same and close to HHV of the conventional diesel (42.7 MJ/kg). However no considerable effect seen on HHV of char products from catalyst added mixtures. On the other hand, due to the SEM images the char products it can be clearly concluded that com-paring with FBR, RKR had the better performance on pyrolysis of the biomass mixtures.

Bu çalışmada polimer ve selüloz içerikli biyokütle malzemeleri, iki farklı katalizör (sepiyolit ve alüminyum boksit) kullanımında ve oksijensiz bir ortamda piroliz edilmiştir. Piroliz işlemleri döner yataklı piroliz reaktör (DYR) ve sabit yataklı reaktör (SYR) olmak üzere iki ayrı reaktörde gerçekleştirilmiştir. Çalışmada biyokütle içeriği bileşen oranları, iki farklı katalizörün aynı oranlarda katılması ve farklı tip reaktör kullanımı gibi parametrelerin son ürüne etkileri belirlenmiştir. Öncelikle belirli oranlarda polimer ve selüloz içeren biyokütle karışımları hazırlanmıştır. Ardından ısıl aktif katalizörler biyokütle karışımlarına eklenmiştir. Deneylerin sonunda elde edilen katı ve sıvı son ürünlerin üst ısıl değer (HHV), element içeriği, parçacık boyutları ve yüzey alanı ölçüm değerleri hesaplanmış ve analiz edilmiştir. DYR ve SYR reaktörlerinden boksit katalizörlüğünde elde edilen sıvı ürünlerin HHV değerleri sırası ile 42,74 MJ/kg ve 40,95 MJ/kg olarak bulunmuştur. Bunun yanında DYR ve SYR reaktörlerinden sepiyolit katalizörlüğünde elde edilen sıvı ürünlerin HHV değerlerinin ise 41,28 MJ/kg ve 38,94 MJ/kg değerlerinde olduğu görülmüştür. Bu değerlerin günümüzde de yaygın olarak kullanılan geleneksel dizel yakıtın HHV değerine (42,7 MJ/kg) oldukça yakın olduğu görülmektedir. Buna karşın elde edilen katı numunelerin HHV değerlerinde kayda değer bir farklılık görülmemiştir. Diğer yandan katı numunelerin SEM görüntüleri incelendiğinde SYR ile kıyasla DYR de gerçekleşen biyokütle karışımlarının pirolizinde daha iyi performans gösterdiği anlaşılmaktadır.
