To　promote　biomass　industry　chain,　and　to　improve　the　value　of　Caragana　korshinskii　Kom＇s　comprehensive　utilization,　research　group　used　microwave　pyrolysis　technology　for　korshinskii　to　obtain　high　quality　of　crude　oil,　and　lots　of　solid　carbon　can　be　prepared　for　high-quality　activated　carbon　by　chemical　activated　method.　This　experiment　is　on　the　preparation　of　activated　carbon　through　chemical　methods,　selecting　activated　agents,　activator　quality　ratio,　activated　temperature　and　activated　time　as　4　effective　factors,　iodine　number　as　the　main　index.　The　orthogonal　experiment　was　carried　out　based　on　the　result　of　single-factor　experiment,　the　process　condition　of　producing　activation　carbon　is　optimized　through　orthogonal　test.　The　results　show　that　the　optimal　process　conditions　of　phosphoric　acid　as　activator　for:　carbon　agent　ratio　of　1:1.5,　activation　temperature　of　550,　activated　time　of　80　min,　under　the　condition　9.8%,　2.77%　and　1013.37　mg/g　correspond　to　its　moisture　content,　ash　content　and　iodine　adsorption　value,　and　the　three　main　indexes　all　reach　the　first　classnational　standard　of　wooden　activated　carbon　for　water　purification.　©　2016,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
