Abstract. Caragana, a shrub which widely distributed in many parts of China, is an available feed and biomass energy resource. Pelletization is one of the promising utilization for Caragana. In this study, chopped Caragana samples were compacted in a piston cylinder under four pressure levels (30,75, 120,165 MPa) and at four moisture content levels (6%, 11%, 16%，21% (w.b.)) to produce pellets. The results showed that applied pressure and moisture content all significantly affected pellet density and density expansion ratio. The pellet density ranged from 775.59±13.33 to 1085.82±8.89 kg/m3. Among them, the pellet density increases first and then decreases with increasing water content, and increases with pressure increasing. According to a comprehensive analysis, Caragana has the highest quality pellet under the conditions of a moisture content of 11% and a pressure of about 120 MPa.
