Description
При нагреве березовой древесины в жидком керосине до 260° происходит процесс пиролиза. При этом выдел ютс 5-7% кислот, значительное количество эфиров, кетонов и фенолов. С постепенным новышением температуры керосина от 95 до 100° из древесины отгон етс 1игроскопическа влага с ничтожным содерл анием кислот, затем при 220-250° выдел етс концентрирозапна жижка. Керосин отгон етс вод ным паром, нолучаема д)евссина бурого цвета обладает достаточно большой механической прочностью, она приобретает равпомерньн цвет от темножелтого до коричневого, в зависимости от конечной температуры. Последнее свойство может быть использовано в мебельном производстве .When birch wood is heated in liquid kerosene to 260 °, the pyrolysis process takes place. This releases 5-7% acids, a significant amount of esters, ketones and phenols. With a gradual increase in the temperature of kerosene from 95 to 100 °, 1ygroscopic moisture is distilled off from the wood with a negligible content of acids, then at 220-250 ° the concentrate-sludge is released. Kerosene is distilled off with water vapor, but the resulting e) eussin of brown color has a sufficiently high mechanical strength, it acquires a uniform color from dark yellow to brown, depending on the final temperature. The latter property can be used in furniture production.
Така древесина вл етс стойкой к гнилостным процессам, поэтому в некоторых случа х этот способ может заменить нропитку.Such wood is resistant to putrefactive processes, therefore, in some cases, this method can substitute for impregnation.
Получающуюс таким образом жижку можно отбирать по фракци м . При этом в средних фракци х жижка может содержать до 30% кислот, что облегчает ее переработку и выделение отдельных комнонентов .The resulting slurry can be collected by fraction. At the same time, in the medium fractions, the slurry may contain up to 30% acids, which facilitates its processing and the isolation of individual components.
Предмет изобретени Subject invention
Способ термической обработки древесины в среде жидких нефтепродуктов , о т л и ч а ю щ. и и с тем, что, с целью сохранени ее механической прочности и максидгального извлечени органических продуктов , древесину нагревают в среде керосина нри температуре не выше 260°, затем остатки керосина и жидкие продукты удал ют перегретым паром.The method of heat treatment of wood in the environment of liquid petroleum products, about tl and h and y y. and in order to preserve its mechanical strength and maxidagal extraction of organic products, wood is heated in kerosene at a temperature not higher than 260 °, then kerosene residues and liquid products are removed with superheated steam.
