Abstract

Fermentation of palm oil mill effluent (POME) produces biohydrogen in a mixture at a specific set condition. This research was conducted to purify the produced mixed biohydrogen via absorption and membrane techniques. Three different solvents, methyl ethanolamine (MEA), ammonia (NH3) and potassium hydroxide (KOH) solutions, were used in absorption technique. The highest H2 purity was found using 1M MEA solution with 5.0 ml/s feed mixed gas flow rate at 60 minutes absorption time. Meanwhile, the purified biohydrogen using a polysulfone membrane had the highest H2 purity at 2~3 bar operating pressure. Upon testing with proton exchange membrane fuel cell (PEMFC), the highest current and power produced at 100% H2 were 1.66 A and 8.1 W, while the lowest were produced at 50/50 vol% H2/CO2 (0.32 A and 0.49 W). These results proved that both purification techniques have significant potential for H2 purification efficiency.
