Description

лигнина в водном растворе аммиака и акислени  кислородом воздуха -при повышенных температуре и давлении с последующей фильтрацией и переработкой полученного твердого остат1ка, отличающийс  тем,. что, с целью упрощени  процесса, увеличени  выхода готового продукта и .повышени  содержани  в нем легкоусво емых форм азота, суопендирование -провод т при гидромодуле 16-20 и канцентрации аммиака 1-3%, а окисление ведут в присутствии катализатора при 120-160° С и давлении 7-15 ати.lignin in an aqueous solution of ammonia and air oxygenation — at elevated temperatures and pressures, followed by filtration and processing of the resulting solid residue, characterized in that that, in order to simplify the process, increase the yield of the finished product and increase the content of easily assimilable nitrogen forms in it, co-suspension is carried out at a water ratio of 16-20 and ammonia concentration of 1-3%, and oxidation is carried out in the presence of a catalyst at 120-160 ° With and pressure of 7-15 ati.

2. Способ по П. 1, отличающийс  тем, что в качестве .катализатора используют соединени  ж-елеза в количестве 0,0001- 0,0002%.2. The method according to claim 1, characterized in that iron compounds in an amount of 0.0001-0.002% are used as the catalyst.
