Abstract

Спосіб одержання вуглецевого адсорбенту на основі лігніно-целюлозної сировини, а саме - стержнів кукурудзяних качанів, включає подрібнення стержнів, фракціонування розміру частинок одержаної крихти, просочування крихти водним розчином ортофосфорної кислоти з подальшою карбонізацією шляхом термічної обробки в печі в газовому середовищі з одночасною хімічною активацією, промивання вугілля гарячою водою до нейтрального рН промивної води для видалення залишків кислоти і висушування одержаного адсорбенту. Лігніно-целюлозну крихту фракціонують в межах 1-, просочують крихту при масовому співвідношенні кислота/крихта 1:1-2, термічну обробку ведуть в середовищі оточуючого повітря протягом 5-15 хв., причому як піч використовують мікрохвильову піч з частотою 2,45 Ггц.Method of producing carbon adsorbent on the basis of lignin-cellulose raw material, namely - corn cob rods, includes grinding of rods, fractionation of particle size of the obtained crumb, impregnation of crumb with aqueous solution of orthophosphoric acid with subsequent carbonization with subsequent carbonization washing the coal with hot water to a neutral pH of the washing water to remove acid residues and drying the resulting adsorbent. The lignin-cellulosic crumb is fractionated within 1-, impregnated the crumb at a mass ratio of acid / crumb 1: 1-2, the heat treatment is carried out in ambient air for 5-15 minutes, and as a furnace using a microwave oven with a frequency of 2.45 GHz .
