Hydrogen can store and deliver usable energy, but it does not typically exist by itself in nature and must be produced from compounds that contain it such as biomass. Hydrogen can be used as fuel which produce from gasification process that used renewable sources as feedstock. Large amount of empty fruit bunch (EFB) has been produced in Malaysia and yet has no specific used in large quantity and it is being incinerated or used as landfill material dumped in the plantation. These situations have led to increased CO2 and other greenhouse gas (GHG) emissions in the atmosphere. During preliminary study, it shows that there are very limited studies being done in the process design development of the hydrogen production by using EFB from oil palm. Despite of tremendous experimental studies done on the effectiveness of using EFB for production of hydrogen, the process implementation in industry is still discouraging. This is due to lack of proven technology and high capital cost of investm...

In Malaysia, the growth of economic is connected to the fossil energy resources which are continued to effect by the growing of energy demand. Hydrogen is an alternative for energy and electricity generation, especially for transportation application and can significantly reduce the carbon monoxide (CO) emission and air pollution. The research on renewable energy especially from biomass such as oil palm empty fruit bunch (OPEFB) can contributes to reduce the concern over the energy insecurity and will help Malaysia in creating a sustainable energy supply. Research on the hydrogen production process by using OPEFB was reported in several papers. However, the review criteria and the best technology for hydrogen production process application are still missing. This paper attempts to develop hydrogen technology database from various types of hydrogen production process of OPEFB. It can be used to determine the most feasible and promising route to be applied. This study is also signific...

Malaysia is one of the largest producers of palm oil and this industry plays an important role in Malaysia economic growth. As this industry grows larger, a significant amount of oil palm waste is generated, creating the problem of overloading biomass waste. Since the oil palm waste has many significant uses such as empty fruit bunches (EFB), the interest in production of hydrogen gas as the renewable energy from EFB also increases. The most common and favorable thermochemical processes to produce the hydrogen gas is gasification process in fluidized bed reactor. Regardless of tremendous experimental studies done on effectiveness of using EFB for production of hydrogen, the process implementation in industry is still discouraging. This is due to lack of proven technology and high capital cost of investment. In this study, a computational modeling was developed for EFB gasification in fluidized bed gasifier using the ASPEN PLUS simulator (v. 8.8) to optimize the gasification tempera...
A heat integrated flowsheet has been designed for hydrogen production from oil palm empty fruit bunch (EFB) via steam gasification with in-situ CO(2) capture. The process energy requirement and cost are calculated from the mass balances, energy balances and the economic model of flowsheet. The flowsheet calculation and cost minimization are carried out using MATLAB. The flowsheet under investigation includes steam generation unit, gasification unit and gas cleaning unit. For heat integration studies on the flowsheet, the pinch analysis is employed to obtain the energy efficient and self-sustained system. The heat integration study is carried out using SPRINT software. The analysis shows that considerable saving can be obtained for steam production using heat integration application as there is a large amount of available waste heat from the gas cleaning and cooling units. The results show that the minimum hot utilities required is 601.85 kJ/h and the minimum cold utilities is 13.82 ...
Bio-Hydrogen from Low Temperature Thermo-Chemical Conversion of Oil Palm Efb
Jurnal Teknologi, 2015
A low temperature thermo-chemical conversion of biomass to maximise the hydrogen-rich sync gas product to replicate a one-step hydrogen production using oil palm empty fruit bunches (EFB) as an alternative process for renewable hydrogen production is studied. The slow pyrolysis with inexpensive and abundant selected catalysts alkali metal hydroxides such as NaOH is conducted in a pyrolyser unit with a continuous feeding system. The bio-hydrogen is expected to be free of CO and CO2, and the process could be optimized at relatively low temperature of 500-600K, which is significantly lower than the normal temperature ranges for biomass gasification process.
