Methane conversion factor
WebMethane conversion rate as the fraction of the GE being converted into methane (IPCC 2001). For other animal categories the default emission factors are taken (Tier 1; IPCC 1997). The emissions from manure depend on the animal category, the amount of manure per animal and the manure management system. For CH 4 a Tier Web10 nov. 2024 · Preliminary tests on a 17 cm long reactor at 1030 °C offered a methane conversion rate of about 18% over 50 hours, and Liu says they have recently made some adjustments to reach 30% conversion.
