This research aimed to produce furfural from oil palm biomass via a biomass-derived solvent (supercritical ethanol) and catalyst (formic acid). The process is 100% biomass-based without the addition of any synthetic chemicals. Ethanol can be produced from biomass through biochemical or thermochemical conversion processes, and formic acid is a by-product of furfural production. Hence, this proposed method is self-sustainable because both can be recycled in the process. Oil palm biomass as a feedstock can address the issue of waste from the palm oil mill industries and turn it into value-added platform chemical such as furfural. In this study, various reaction parameters were evaluated including temperature (240-280 ̊C), reaction time (1-30 min), biomass solid loading (0.4-0.8 g), and alcohol: acid ratio (1:1 and 1:2), in a high-pressure and high-temperature batch reactor. The highest furfural yield of 35.8% was obtained in this study, comparable to other commercial and conventional methods. Although the formation of furfural is promoted by formic acid, the reaction temperature significantly impacted the outcome. The significant role of supercritical ethanol as both solvent and reactant may explain the minimal effect of formic acid as a catalyst in the reaction. The high yield of furfural under supercritical ethanol conditions proven in this study illustrates the great potential of this production method.

Generation of biofuels from renewable resources such as lignocellulosic biomass is a promising approach to reduce the sole reliability on the depleting fossil fuel. The aim of this work is to assess the potential environmental impact of bioethanol production from oil palm frond in a conceptual oil palm based biorefinery model, utilizing wet disc milling as a pretreatment method. A cradle-to-gate approach was selected, beginning with the harvesting and transportation of the frond petiole from the plantation, followed by production of oil palm frond petiole sugars via pretreatment and saccharification prior to bioethanol fermentation, and finally purification of the fermentation products to obtain anhydrous bioethanol. A life cycle assessment was performed using CML 2 baseline 2000 method (SimaPro v8.0), where ten impact categories were evaluated. It was found that the most significant environmental impact was from sugar recovery process with contribution of more than 90 %. This is mainly due to high power consumption by wet disc milling during pretreatment. Apart from that, production of enzyme and chemicals which were used during saccharification consumes high energy thus contributing major problems to the surrounding. Finding of this study helps to identify the hotspot which can be improved to establish a more energy efficient and greener system for bioethanol production from oil palm frond petiole sugars.

Behaviour of porous media combustion is mainly relay of material used in reaction and preheat zone to possesses high thermal efficiency. Present study deals development of porcelain foam porous media which shall acts as preheat zone to obey peclet number. While in reaction zone consist of alumina foam. In a dual layered micro burner the thickness of reaction and preheat zone was kept at 15 and 10 mm respectively. Burner was developed to achieve not just conventional free flame but also generate submerged flame, varying equivalence ratio (ER). Further, premixed combustion performance was enhanced by running ER below 1, which is lean condition. While optimum ER for surface flame and submerged flame was found to be 0.7 and 0.5 respectively. Maximum thermal efficiency during for surface and submerged flame was turn out to be 90 % and 38 % respectively.

We have established a processing method to fabricate three-dimensional porous carbonate apatite (CO3Ap) with interconnected porous structure and improved mechanical strength. Briefly, porous CO3Ap materials were produced via phosphorization of porous calcite precursor in hydrothermal condition. In order to make porous calcite precursor, negative replication of modified polyurethane foam template was conducted. In this study, an in vivo behavior of that porous CO3Ap was evaluated. The interconnected porous CO3Ap material was implanted in the tibia of Japanese male rabbits and removed after a period of 6 months. Micro-computed tomography (μ-CT) scanner and histological analysis were used to characterize the bone formation response of the porous CO3Ap. The results suggest that porous CO3Ap with enhanced mechanical strength was not only osteoconductive but also bioresorbable therefore it could be used as bone substitute material. © 2016 Trans Tech Publications, Switzerland.

Addition of porous materials in reaction zone give rise to significant improvements in combustion performance. In this work, a dual layered micro porous media burner was tested for stable flame and emissions. Reaction and preheat layer was made up of discrete (zirconia) and foam (porcelain) type of materials respectively. Three different thickness of reaction zone was tested, each with 10, 20 and 30mm. Interestingly, only 20mm thick layer can able to show better thermal efficiency of 72% as compared to 10 and 30mm. Best equivalence ratio came out to be 0.7 for surface and 0.6 for submerged flame conditions. Moreover, emission was continuously monitored to detect presence of NOx and CO, which were under controlled limits.
