Removal of hydrogen sulfide as ammonium sulfate from hydropyrolysis product vapors |
摘要 |
A system and method for processing biomass into hydrocarbon fuels that includes processing a biomass in a hydropyrolysis reactor resulting in hydrocarbon fuels and a process vapor stream and cooling the process vapor stream to a condensation temperature resulting in an aqueous stream. The aqueous stream is sent to a catalytic reactor where it is oxidized to obtain a product stream containing ammonia and ammonium sulfate. A resulting cooled product vapor stream includes non-condensable process vapors comprising H2, CH4, CO, CO2, ammonia and hydrogen sulfide. |

1. A method for processing biomass into hydrocarbon fuels comprising:
processing a biomass in a hydropyrolysis reactor resulting in hydrocarbon fuels, char, and a process vapor stream; cooling the process vapor stream to a condensation temperature resulting in an aqueous stream; sending the aqueous stream to a catalytic reactor; injecting air into the catalytic reactor to obtain an aqueous product stream containing ammonia and ammonium sulfate; and obtaining a cooled product vapor stream, containing non-condensable process vapors comprising H2, CH4, CO, CO2, ammonia and hydrogen sulfide. |
