For this reason, the effect of temperature was investigated using this catalyst in further runs.In the experiments carried out at different temperatures, oil yields firstly increased and then decreased with further increase in reaction temperature; whereas, the amount of gas formed during the liquefaction reaction increased and solid residue decreased steadily with temperature.

Abstract

In this study, the effects of catalysts (Na2CO3, K2CO3 and HCOOH) and temperature on the liquefaction of poplar wood slurries were investigated.In the experiments undertaken to elucidate the effect of various catalysts at 250°C and for 2 hour liquefaction duration time, HCOOH was found to be more effective catalyst than the other alkaline catalysts when both oil yields and their C contents were considered. For this reason, the effect of temperature was investigated using this catalyst in further runs.In the experiments carried out at different temperatures, oil yields firstly increased and then decreased with further increase in reaction temperature; whereas, the amount of gas formed during the liquefaction reaction increased and solid residue decreased steadily with temperature.

Özet

Bu çalışmada % 10'luk kavak odunu çamurunun sulu fazda sıvılaştırılmasında katalizörlerin ve sıcaklığın etkisi incelendi.Sıvılaştırma üzerine çeşitli katalizörlerin (Na2CO3, K2CO3 ve HCOOH) etkisinin 250°C sıcaklık ve 2 saat' lik sıvılaştırma süresi için araştırıldığı deneylerde, HCOOH'in gerek yağ verimi gerekse yağdaki karbon yüzdesi yönünden diğer alkali katalizörlere göre daha etkili olduğu bulundu. Bu yüzden sıcaklığın etkisinin incelendiği deneylerde HCOOH katalizör olarak kullanıldı.Farklı sıcaklıklarda (250, 300 ve 350°C) yürütülen deneylerde yağ verimi sıcaklıkla önce artmakta, ancak sıcaklığın daha fazla artırılmasıyla azalmaktadır. Buna karşılık reaksiyonda oluşan gaz miktarı sıcaklıkla sürekli olarak artmakta ve katı artık miktarı azalmaktadır.
