Bioethanol is one of the most promising biofuels from renewable resources. There are several biomass materials which can be the source of bioethanol production. From those renewable sources, corn was selected as a favorable feed for bioethanol production plant. This is because of corn is the most produce agriculture compare to other biomass materials. Aspen plus v8.8 was used for modelling and thermodynamic design in this work. The result shows that 0.63 million barrels of ethanol per year can be produced from 249278 lb/h corn.

Global warming and air pollution have become one of the important issues to the entire world community. Exhaust emissions from ships has been contributing to the health problems and environmental damage. This study focuses on the ferry routes from ferry terminal in StulangLaut, Johor Bahru to Batam Island, Indonesia because it is one of the world’s most congested straits used for international shipping where located on the border among three countries of Indonesia, Malaysia and Singapore. This study will identify and predictCarbon Dioxide (CO2) emission from the marine transport from ferry terminal in StulangLaut, Johor Bahru along its routes to Batam Island, Indonesia.

Investigating the reforming characteristics and optimal operating circumstances of the biogas reforming reaction for the hydrogen-rich gas generation was the target of this work. Besides, parametric broadcast studies were executed, to increase the hydrogen generation and methane conversion rate, wherein there were the differences of the CH4 flow ratio, steam flow ratio, CO2 flow ratio, and catalyst adding in the reactor. Temperature (100–1000 oC), pressure (1–20 atm) and steam to fuel (S/F) ratio (1–9) were three general varieties of settings to discover equilibrium composition of the products. S/F ratio indeed was effective on hydrogen generation, through the whole range of temperature examination. On the other hand, hydrogen mole fraction dropped by developing the pressure starting 1 to 20 atm. At varied S/F ratios, temperatures and pressures, the solid carbon formation does not found a problem during the biogas reforming. When the temperature reach 750 oC, the conversion of methane was maximized in different pressure and S/F ratio. The maximum hydrogen mole fraction was obtained in S/F ratio of 9 at atmospheric pressure, however; by increasing the pressure to 20 atm, hydrogen decreased significantly. Energy consumption was increasing by rising the temperature in both different pressure and S/F ratio for all gases.
