Pyrolysis Oil Stabilisation by Catalytic Hydrotreatment

Oct 27, 2010In any case, without active catalyst or (high pressure) hydrogen, significant charring of pyrolysis oil occurs. Reduction of charring is possible by applying a (relatively) low temperature catalytic hydrotreatment at 175 to 250 C, in which reactive components in the oil are 'stabilized'. Get price
