Ni-brown coal char composite with the Ni loading of 20.3 wt % were applied for low temperature gasification of a wood biomass. The composite was fabricated with the simple manner, immersion of brown coal into the Ni amine complex solution and drying followed by heat treatment between 400 and 650℃. The gasification experiments were carried out between 400 and 600℃ with a fixed-bed reactor. The biomass was pyrolyzed up to 900℃. The composite showed better catalytic performance for tar reforming into gaseous species compared to that of previous Ni loaded brown coal char with the Ni loading of ca. 10 wt %. Lower temperature fabrication of the composite significantly reduced the grain size of Ni, providing better tar reforming performance.
