Description
Изобретение относитс к химической очистке кислородогетероциклических соединений , в частности фурфурола.This invention relates to the chemical purification of oxygen heterocyclic compounds, in particular furfural.
Целью изобретени вл етс увеличение выхода очищенного продукта и степени очистки фурфурола за счет повышени адсорбционной емкости адсорбента.The aim of the invention is to increase the yield of the purified product and the degree of purification of furfural by increasing the adsorption capacity of the adsorbent.
Поставленна цель достигаетс тем, что известный адсорбент дл очистки фурфурола от продуктов его осмолени , включающий оксид алюмини , имеет следующий состав: щелочной оксид алюмини 40 - 60%; цеолит МдА остальное.This goal is achieved by the fact that the known adsorbent for purification of furfural from the products of its tarification, including aluminum oxide, has the following composition: alkaline aluminum oxide 40–60%; zeolite mda rest.
Проведены опыты по адсорбционной очистке фурфурола на лабораторном адсорбере диаметром 20 и высотой 200 мм при комнатной температуре и скорости подачи фурфурола 0.120 л/ч. Окислительную регенерацию адсорбента после сдува оставшегос фурфурола и термодесорбции примесей проводили при 500 - 530°С. В опытах использован фурфуроп (технический ) состава, мас.%: карбонильные соединени 92,94; смолистые вещества 5,5; вода 1,5; органические кислоты 0.06. Содержание перекисей составл ло 0,48 мг-экв/л и сернистых соединений 0.0192 г/л.Experiments were performed on the adsorption purification of furfural on a laboratory adsorber with a diameter of 20 and a height of 200 mm at room temperature and a feed rate of furfural of 0.120 l / h. Oxidative regeneration of the adsorbent after blowing the remaining furfural and thermal desorption of impurities was carried out at 500 - 530 ° C. In the experiments, a furforop (technical) composition was used, wt.%: Carbonyl compounds 92.94; resinous substances 5.5; water 1.5; organic acids 0.06. The peroxide content was 0.48 mEq / l and sulfur compounds 0.0192 g / l.
Результаты сведены в таблицу, где представлены полученные показатели очистки фурфурола при использовании предлагаемого адсорбента с различным соотношением компонентов.The results are summarized in the table, where the obtained indicators of purification of furfural are presented using the proposed adsorbent with a different ratio of components.
Из таблицы следует, что абсорбент предлагаемого состава (примеры 1 - 3) в процессе очистки фурфурола обладает значительно более высокой адсорбционной емкостью, равной 0,062 - 0,068 кг/кг, что соответственно обеспечивает повышение выхода очищенного фурфурола до 24,4 - 28,0 кг/кг, степени удалени смолистых веществ до 98.8 - 100,0%, воды до 62,8 - 65.0%. органических кислот до 50,0 - 52,6%, перекисей до 62,4 - 64,4%. сернистых соединений до 62,0 - 86,8%.The table shows that the absorbent of the proposed composition (examples 1 - 3) in the furfural purification process has a significantly higher adsorption capacity of 0.062 - 0.068 kg / kg, which accordingly provides an increase in the yield of purified furfural to 24.4 - 28.0 kg / kg, the degree of removal of resinous substances to 98.8 - 100.0%, water to 62.8 - 65.0%. organic acids up to 50.0 - 52.6%, peroxides up to 62.4 - 64.4%. sulfur compounds up to 62.0 - 86.8%.
Использование предлагаемого адсорбента позволит повысить качество очищенного фурфурола за счет увеличени глубины удалени таких примесей, как вода, органические кислоты, перекиси, сернистые соединени повысить производительность установки адсорбционной очистки фурфурола за счет увеличени выхода очищенного продукта.The use of the proposed adsorbent will improve the quality of purified furfural by increasing the depth of removal of impurities such as water, organic acids, peroxides, sulfur compounds, and improve the performance of the installation of adsorption purification of furfural by increasing the yield of the purified product.
