Abstract
A comprehensive experimental and modelling study is done on the Biomethanation from water hyacinth plant (Eichhorniacrassipes) to optimise the yield of methane gas with three different catalysts. Water hyacinth grows in the rivers, lakes etc. and it is a huge source of biomass that is easily available. The costs related issues are therefore quite considerable. The experiment of catalytic Biomethanation on water hyacinth was carried out under anaerobic condition in semi-batch digester and batch digester under controlled pH with range of 6.2 to 7.12 and at temperature 30-40°C. In this study, the pH, temperature, VFA (volatile fatty acid) was measured once in every week. This present research incorporates a comparative study on the yield of methane gas between control set-up and catalytic set-up.
