Abstract

One of the abundant biomass resources in Indonesia is water hyacinth, which can be converted into energy through pyrolysis. This research explores the effect of temperature on the co-pyrolysis process of a mixture of water hyacinth and young coal to produce bio-oil, gas, and char. The method used is pyrolysis with temperature variations on the mixture of water hyacinth and young coal in a batch reactor.  The testing was conducted at a temperature of 400°C with various compositions of water hyacinth and coal mixtures, and the resulting products in the form of bio-oil, gas, and char were then measured to determine the yield. The research results show that in the pyrolysis of pure water hyacinth, gas production reaches 120 grams, bio-oil 108 grams, and char 72 grams. The addition of coal up to 30% increases char production to 113 grams, but decreases gas production to 94 grams and bio-oil to 87 grams.  The gas produced is dominated by methane (67.315%) in a mixture of 70% water hyacinth and 30% coal, while hydrogen reaches 33.721% in pure water hyacinth.
