Evaluation of Effect of Steam Pretreatment on Water and Liquor Absorption of Wood Particles
This research was investigation of steaming pretreatment on water and liquor absorbtion by wood particles. In this study, wood particles steamed at two different temperature (110oC- 140oC), and then were saturated in water and liquor at two different temperature (25oC, 100oC). Liquor was supplied wi...

| Summary: | This research was investigation of steaming pretreatment on water and liquor absorbtion by wood particles. In this study, wood particles steamed at two different temperature (110oC- 140oC), and then were saturated in water and liquor at two different temperature (25oC, 100oC). Liquor was supplied with two different consistencies. That is, sodium hydroxide %9, sodium sulfite %6 and sodum hydroxide %18, sodium sulfite %12. Result of this research has shown that maximum absorbed water was %95.5. It was treated with steam of 140oC for one hour, and minimum absorbed water was %68.9. It was treated with steam of 110oC for half an hour.
So, maximum of absorbed liquor was %108.64. It was treated with steam of 140oC for one hour. And least of absorbed liquor was %99.88. It was treated with steam of 110oC for half hour. Moreover, maximum of water and liquor absorption for control samples were %94.98 and %107 respectively. However, they were less than treated samples. |
