174 RELATIONSHIP BETWEEN METHANE AND HYDROGEN PRODUCTION IN AN ANAEROBIC FAECAL INCUBATION SYSTEM

Anaerobic Treatment of Glycerol for Methane and Hydrogen Production

This work focused on glycerol exploitation for biogas and hydrogen production. Anaerobic digestion of pure glycerol was studied in a continuous stirred tank reactor (CSTR), operated under mesophilic conditions (35C) at various organic loading rates. The overall operation of the reactor showed that it could not withstand organic loading rates above 0.25 g COD L d, where the maximum biogas (0.42 ...

Comparative study of hydrogen and methane production in the human colon using caecal and faecal homogenates.

Rates of hydrogen and methane production were compared in caecal and faecal homogenates in six methane producers. Faecal homogenates produced hydrogen and methane in the absence of and after the addition of lactulose, whereas caecal homogenates produced hydrogen but little methane.

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
