Humulus lupulus, a kind of hop plant agricultural waste was pyrolyzed in a fixed bed reactor with a heating rate of 10⁰C min-1 in the presence of N2 atmosphere. The effect of pyrolysis temperature was investigated at 450, 500, 550 and 600ᴼC. The characterization of solid product (bio-char) and liquid product (bio-oil) was performed by spectroscopic and chromatographic techniques. Column chromatography, GC-MS and FT-IR analyses were used for the characterization of bio-oil; whereas FT-IR and SEM were the techniques for bio-char characterization. Experimental results showed that liquid products are available to evaluate as valuable chemicals and environmentally friendly synthetic fuels whereas solid products can be used as a low-cost adsorbent for wastewater treatments.
