Summary Hi(her reaction temperature and lon(er holdin( period ,ill produce more
uniform and denser product
Hi(her reaction temperature and lon(er holdin( period ,ill produce products,ith lo,er or(anic chlorine content.
The or(anic chlorine in the products ,as con6erted to inor(anic chlorine- ,iththe lo,est or(anic chlorine content of %.! 3! 3&=%% ppm5 in the ra, MSW.
The inor(anic chlorine can then e ,ater ,ashed and de,atered to reduce th
total chlorine content in the products.
Heatin( 6alues of the hydrothermally treated products ,ere not sustantiallyaltered. The hi(hest heatin( 6alue recorded ,as 4" M;?0(- ,ith an a6era(e for
all products of 4% M;?0(- ,hich is almost e@ual to that of lo,9(rade su9ituminous coal.
The inno6ati6e hydrothermal treatment can e considered as an alternati6e
MSW treatment that produces a safe- usale- and lo, chlorine content solidfuel
