Description
Известно, что из древесных опилок, древесной муки, мелко иэмельченного корь , сена, соломы, сухих хвойных игл и листьев после их обработки посредством предварительного в течение некоторого времени нагревани при температуре около 180°, под уменьшенным давлением или в атмосфере инертного газа и последующего прессовани (при температуре от 150-250 под давлением 600-1000 кг/см) получаютс издели коричневого или черного цвета, отличающиес механической прочностью, стойкостью к действию паров воды, воды, слабых кислот и щелочей. Автором насто щего изобретени предложено вышеуказанные мелкоизмельченные материалы подвергать перед прессованием пропитке (при кип чении или.т. п.) растворами или эмульси ми солей, железа , меди, марганца, кобальта, алюмини и других металлов, обычно примен емых в качестве крэкинг-катализаторов. Дл приготовлени солей, концентраци которых в растворах или эмульси х может быть невысокой (1%-10%), следует брать органические кислоты, как например , муравьиную, уксусную, фталевую, нафтеновые, а также оксикислоты, продукты окислени нефт ных масел и т. п.It is known that from sawdust, wood flour, finely chopped measles, hay, straw, dry conifer needles and leaves after they are processed by preheating for some time at a temperature of about 180 °, under reduced pressure or in an inert gas atmosphere and subsequent pressing (at a temperature of 150-250 under a pressure of 600-1000 kg / cm) brown or black products are obtained, characterized by mechanical strength, resistance to the action of water vapor, water, weak acids and alkalis. The author of the present invention has proposed to apply the above-mentioned finely divided materials before pressing to impregnate (during boiling or the like) solutions with solutions or emulsions of salts, iron, copper, manganese, cobalt, aluminum and other metals commonly used as cracking catalysts. . To prepare salts whose concentration in solutions or emulsions may be low (1% -10%), organic acids, such as formic, acetic, phthalic, naphthenic, as well as hydroxy acids, oil oxidation products, etc, should be taken. P.
Пропитанные материалы высушивают и прогревают при температуре выше 150°, а затем прессуют при 180-250°. Про (204)Impregnated materials are dried and heated at temperatures above 150 °, and then pressed at 180-250 °. Pro (204)
грев в присутствии распыленных металлов их окислов солей ведет к сокращению срока, необходимого дл крэкинга перечисленных материалов и выделени первоначальной молы.warming in the presence of sputtered metals, their oxides of salts leads to a reduction in the time required for the cracking of these materials and the release of the original mole.
Пример 1. 1000 г древесной еловой муки пропитывают 5%-м раствором муравьинокислого железа или меди, высушивают при 110°, а затем прогревают при помешивании и под вакуумом (ок. 80 мм) при температуре 180° в течение 2 час. и обработанный таким образом материал прессуют под давлением в 800 кг/см при температуре 210-220°.Example 1. 1000 g of fir tree flour are impregnated with a 5% solution of iron or copper formic acid, dried at 110 °, and then heated with stirring and under vacuum (about 80 mm) at a temperature of 180 ° for 2 hours. and the material thus treated is pressed under a pressure of 800 kg / cm at a temperature of 210-220 °.
Пример 2. 1000 г древесной дубовой муки пропитывают 5%-м раствором нафтената меди в ксилоле, отжимают и прогревают в течение 2 часов при 180- 200°, после чего прессуют, как указано в примере 1.Example 2. 1000 g of wood oak flour are impregnated with 5% copper naphthenate solution in xylene, squeezed and heated for 2 hours at 180-200 °, and then pressed as indicated in example 1.
Пример 3. 1000 г измельченной на триплексе Кернера соломы или сена пропитывают 10%-м раствором уксуснокислого алюмини , отжимают и высушивают при 100°, после чего прогревают при температуре 210-240° и прессуют, как указано в примере 1,Example 3. 1000 g of crushed on Kerpner triplex straw or hay is impregnated with 10% aluminum acetate solution, pressed and dried at 100 °, then heated at 210-240 ° and pressed, as indicated in example 1,
