Latest Patents

Jian Li holds a patent for a system titled "Low temperature recovery of kraft black liquor." This invention utilizes three separate reactors for liquor pyrolysis, sulfate reduction, and carbon plus organics combustion. The process involves pyrolyzing oxidized black liquor in a fluid bed reactor at a temperature of 600 degrees Celsius or lower. The resulting char, which contains sodium carbonate and sodium sulfate along with a significant amount of carbon, is separated from the pyrolysis gases. This char is then introduced into an indirectly heated reactor for the reduction of sodium sulfate to sodium sulfide in the solid state. The reduced char is subsequently cooled and leached to produce green liquor. The leached char and gases from the pyrolysis and reduction reactors are combusted in a fluid bed combustion unit, operating below the melting point of sodium carbonate and sodium sulfate mixtures. This innovative system effectively removes volatile oxidized sulfur species formed during combustion.
