A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...

Residence time is a critical factor in determining the size of an open face biofilter. Four test biofilters were constructed with media comprised of yard waste compost and brush chips to compare 8 s. and 4 s. residence time. Biofilter performance was monitored for ten months by measuring pressure drop, moisture content, odor threshold, hydrogen sulfide, and ammonia concentrations. Odor reductio...
