In this work,a comparative study of biogas production from cow dung,tomato waste,food waste and spinach was done under the same operating conditions. Biogas production was measured using water displacement method for a period of 14 days and at an average temperature of 32.5℃. The results showed that cow-dung produced more biogas compared to other substrates at p H between 6.5 and 7.1.

A polyhydroxybutyrate-co-hydroxyvalerate（PHBV） is mingled with natural rubber latex（R） to develop its mechanical property of the blend. Normally, substantial effects of the PHBV are hard, fragile, and inelastic, whereas the natural rubber is represented itself as very high elastic matter. The mixtures between the PHBV and natural rubber latex（R） are considered in different proportions. The PHBV solutions（w/v） are defined suitability at 1%（P1）, 2%（P2）, and 3%（P3）. Their liquid mixtures of the PHBV to natural rubber latex（P:R） are fabricated the blended films in three different ratios of 2:3, 1:1 and 3:2, respectively. The PHBV blended films are characterized the crystallinity form by x-ray diffractometry（XRD）, which are appeared their identity crystals at 13.30 and 16.68 degree（2θ）. Mechanical characterizations of the blends are examined by a universal testing machine（UTM）. The average elastic moduli of P1, P2, and P3 mixtures are indicated as 773, 955, and 1,007 k Pa, respectively. Their tensile strengths, similarly to elastic moduli, enhance with the PHBV concentrations. The effects of mechanical behaviors and crystallinity reveal that the PHBV blends can be improved their properties by more flexible with natural rubber latex.

One of the main problems of palladium based catalysts for a direct formic acid fuel cell (DFAFC) is their low stability during a long-term operation. In these studies, the Pd-ZrO2catalyst supported on the multiwall carbon nanotubes (MWCNTs) was prepared and thermo-chemically treated. These catalysts were tested in a fuel cell for formic acid electrooxidation, and their chemical composition and structure were characterised by the XPS, STEM, HR-TEM and XRD techniques. It was found that the Pd-ZrO2/MWCNTs catalyst after synthesis causes oscillations of the cell voltage during operation resulting in significantly higher deactivation resistance than that of Pd/MWCNTs. This may be attributed to the "self-cleaning" mechanism of poisoned Pd catalyst by carbon monoxide through the electrochemical oxidation of COads(adsorbed) to CO2(gas). © 2015 Hydrogen Energy Publications, LLC.

Establishment of biomass supply chain is preliminary stage for biomass energy production especially in proposing potential processing plant location. Most of the relevant biomass is produced in abundance in agriculture sector. In Malaysia, biomass supply is obtained mainly from oil palm plantation which governed under Federal Land Development Authority. Biomass supply chain deals with harvesting, storage, pretreatment and transportation. Low energy density of biomass combined with availability of biomass that is widely distributed contributes huge constraints to the problem. To address this issue, P-graph modelling is used as the methodology to solve combinatorial complexity of the biomass supply chain in Federal Land Development Authority Jengka. Few possible locations for building new biomass processing plant and storage hubs were introduced in the optimisation problem. Existing plant mills, hubs and possible plant locations were interconnected to create a network. Fuel consumption for transportation was calculated by taking into account the road profiles of the routes in Jengka. The resulting solution from Accelerated Branch and Bound algorithm in P-graph shows that the optimal solution is through building new plant in location 1, 2 and 4 for a profit of 77.35 M MYR/y (18.3 M €/y).

In this work, commercial cellulases and hemicellulases were evaluated for their hydrolytic activity towards pretreated oil palm empty fruit bunches (OPEFB). A total of three commercial cellulase preparations, Novozyme Celluclast®, Novozyme Cellic®Ctec, Dupont Accellerase®1500, and a commercial hemicellulase preparation, Novozyme Cellic®Htec, were evaluated. The assays were performed either using the cellulase alone or cellulase in combination with the hemicellulase, formulated at different enzyme activity ratios. Among the three cellulases, the Novozyme Cellic®Ctec yielded the highest reducing sugars, whereby 32.9% hydrolysis yield of OPEFB was achieved. The addition of the commercial hemicellulase to Celluclast® and Accellerase®1500 enhanced OPEFB hydrolysis. However, the addition of the hemicellulase to Cellic®Ctec, failed to enhance the production of the reducing sugars. Nevertheless, the amount of reducing sugars produced using Cellic®Ctec alone was the highest when compared to other enzyme combinations. It can be concluded that among the three commercial cellulases evaluated, the Novozyme Cellic®Ctec is the best enzyme for OPEFB hydrolysis.

Total Site Heat Integration (TSHI) is an extension of Pinch Analysis for energy recovery between processes via centralised utility system. Locally Integrated Energy Sector (LIES) is introduced to integrate renewable energy sources and urban energy consumptions with industrial process. This concept has been extended to utilise the industrial low grade heat for district heating system. However, the concept has not been considered for district or centralised space cooling system which are more demanded in tropical countries. In tropical countries like ASEAN, residential and service buildings consumed 59% of the total energy consumption. For Malaysia, the energy consumption for buildings sector is projected to increase by 3.1% per year between 2011 and 2035. The main contributor for this high energy consumption is the cooling system requirement, which includes air conditioners and refrigerators. Industrial low-grade heat can be utilised for operating an absorption refrigerator to generate cooling. This can reduce the energy consumptions for industrial processes, as well as space cooling proposes. This paper introduces a new methodology which incorporates absorption chillers in TSHI to reduce the site cooling requirements. The methodology is illustrated by a literature case study.

Use of corn steep liquor as an economical nitrogen source for biosuccinic acid production by Actinobacillus succinogenes

引用

IOP Conference Series: Earth and Environmental Science 2016年第1期36卷

作者： J P Tan J M Jahim T Y Wu S Harun T Mumtaz Chemical and Process Engineering Department Faculty of Engineering and Built Environment Universiti Kebangsaan Malaysia 43600 UKM Bangi Selangor Malaysia.

Expensive raw materials are the driving force that leads to the shifting of the petroleum-based succinic acid production into bio-based succinic acid production by microorganisms. Cost of fermentation medium is among the main factors contributing to the total production cost of bio-succinic acid. After carbon source, nitrogen source is the second largest component of the fermentation medium, the cost of which has been overlooked for the past years. The current study aimed at replacing yeast extract- a costly nitrogen source with corn steep liquor for economical production of bio-succinic acid by Actinobacillus succinogenes 130Z. In this study, a final succinic acid concentration of 20.6 g/L was obtained from the use of corn steep liquor as the nitrogen source, which was comparable with the use of yeast extract as the nitrogen source that had a final succinate concentration of 21.4 g/l. In terms of economical wise, corn steep liquor was priced at $ 200 /ton, which was one fifth of the cost of yeast extract at $ 1000 /ton. Therefore, corn steep liquor can be considered as a potential nitrogen source in biochemical industries instead of the costly yeast extract.
