Анаэробное разложение отходов кормов для домашних животных как сырьевого источника для получения водорода из метана

Потенциальным сырьем для получения водорода (основного носителя для накопления, хранения и транспортировки энергии) является метан из биогаза. Продемонстрирован подход к получению в мезофильных условиях биогаза с высоким содержанием метана (69-72%) из отходов коммерческих сухих и влажных кормов для собак и кошек. За 27-28 суток в анаэробных условиях степень биотрансформации отходов составила 60-88%. В результате минерализации обводненных органических отходов содержание аммонийного азота и фосфора в виде фосфатов составило 676-887 мг NH4 +/л и 77-160 мг РО4 3-/л, соответственно. В анаэробно обработанном стоке наблюдалось накопление сульфид-ионов до 22 мг/л. Полученные по завершению биотрансформации отходов кормов для домашних животных твердый осадок и анаэробно обработанный эффлюент (жидкая фракция) являются потенциальным органическим удобрением для нужд сельского хозяйства, а метан из биогаза – сырье для получения водорода и чистого углерода для нужд наноиндустрии.
