Biocomposite Material

A case study was performed, concerning the behavior and degradation of a polymeric biocomposite material – “liquid wood”. This material is biodegradable and it is obtained from renewable resources. Three presentation forms – Arbofill Fichte, Arboform F45 and Arboblend V2, were subjected to the action of external factors present in a marine environment. The results pertaining to the change in the physico – chemical properties of “liquid wood” when subjected to the action of seawater and seawater microorganisms, with significant – but nevertheless positive – consequences upon the environment. The material exhibits good performance after the surface and mass stabilization – due to water, C, Na, Cl and O absorption. As such – due to the emergence of a protective organic biofilm – growth of microorganisms significantly decreases and electric conductivity increases. This case study may be viewed as a starting point for subsequent studies of “liquid wood”.

Transport Behaviour

Shortchained alkylphenols (SCAP) represent a main constituent of crude oil and coal liquefaction products. Due to their specific oil/water partitioning behaviour and high aqueous solubility they can be detected in oil exploitation waters and groundwaters affected by various spills near oil pipelines, oil exploitation sites and coal liquefaction plants. New efficient and powerful analytical techniques have been developed that allow the identification of all 34 individual compounds (C0-C3) without derivatisation and in complex matrices. Due to the different physico-chemical properties of the SCAP, differential transport behaviour in groundwater can be observed, changing the relative concentrations of SCAP downgradient in space and time. These characteristic ratios can be employed to derive information on migration direction and the ageing of the source of contamination. A case study is presented to illustrate the use of this new tool.

The paper characterized and transesterified castor seed oil. The resulting product was tested as feedstock for biodiesel production. It was carried out at the Department of Mechanical Engineering, the Federal University of Technology, Akure, Ondo State, Nigeria, over a period of eight months. The oil was extracted in a soxhlet extractor with n-hexane as the solvent. The oil obtained was filtered and then characterized. Transesterification was carried out using a laboratory scale biodiesel processor. The fuel and physico-chemical properties of the oil and its biodiesel were determined following ASTM, EN and AOCS methods. The results revealed that all the properties of the biodiesel are within the ASTM limits for biodiesel except the kinematic viscosity. The oil contains 89% ricinoleic acid and has high solubility in methanol due to the hydroxyl group and requires minimum amount of catalyst to give maximum biodiesel yield. The heating value obtained for the oil and its biodiesel were 32 MJ/kg and 38 MJ/kg. The castor seed oil investigated has oil content of 34%, and the properties characterized are all within the limits for biodiesel.  Castor oil has excellent solubility in methanol and hence theoretically an ideal feedstock for biodiesel production.
