Abstract
In a pyrolysis gasification and reforming process of waste and biomass at low temperature of about 700 ℃, high concentration hydrocarbons in the gas and tar are formed. Therefore, by using hydrogenation catalysts, the method for efficiently reducing benzene and other lower hydrocarbons included in the reformed gas was examined by experiment using model gas. It became clear that all of benzene converted into methane at the temperature range of about 250-300℃ under the steam existence, lower hydrocarbons (ethylene, ethane and propylene) were also converted into methane. In the system coexisted with benzene and lower hydrocarbon, all of them converted into methane at 300 ℃.
