Method and system for converting associated gas

A gas conversion system to form a product gas from an associated gas stream, wherein the associated gas stream contains methane and non-methane hydrocarbons, the gas conversion system comprising:

• a steam generator capable of receiving system water and outputting steam;
• a mixing valve system capable of flow controlling at least a portion of the associated gas stream and the steam, and outputting a feed gas which is a mixture of the steam and the at least a portion of the associated gas stream;
• a super heater capable of receiving the feed gas and superheating the feed gas to a predetermined temperature range to form a superheated feed gas;
• a heavy hydrocarbon reactor containing a first catalyst having a leading edge and capable of receiving the superheated feed gas onto the leading edge and cracking a portion of non-methane hydrocarbons of the superheated feed gas into carbon oxides and hydrogen to form a heavy hydrocarbon reactor wet reformate comprising the associated gas stream methane, the carbon oxides, and the hydrogen;
• and
• a synthetic natural gas generator containing a second catalyst capable of receiving the heavy hydrocarbon reactor dry reformate to convert a portion of the carbon oxides and the hydrogen into converted methane to form a synthetic natural wet processed gas containing the associated gas stream methane and the converted methane, wherein the synthetic natural wet processed gas has an overall higher methane mole fraction than the associated gas stream.
