Oil Palm Trunk
Plywood manufacture waste (60%)
Generated every >25 years cycle during replanting Cannot be used as timber as is. Current utilization- plywood manufacture which uses only 40% 60% wastes unutilized

Output
Oil palm trunk (OPT) ~ potential feedstock for syngas production Gasifying agent ~ air, steam, O2 and CO2 Syngas ratio ~ 1.33 (S/C = 1.00) When using higher S/C, syngas ratio = 1.84 (H2 = 36.4%, CO = 19.7%) using steam with S/C = 3.20 Syngas ratio > 1 ~ Potential for DME production DME used for fuel engine DME ~ lower content Nox emissions, less engine noise and smoke production

Output
Optimum conditions for DME production using commercial catalyst obtained for duration of 5 hours reaction time; Reaction pressure = 2 MPa Reaction Temperature = 280 0C Feed Gas Flow Rate = 50 ml/min Catalyst weight = 3 gram GHSV = 1000 ml/g.cat.hr This condition used for DME production using local catalyst (Catalyst 1 & Catalyst 2) Catalyst 1 (0.72%) produced higher yield of DME compared to commercial catalyst (0.40%) ~ potential as local catalyst Higher yield can be obtain if increase the duration of synthesis reaction time until steady state condition achieve.
