Abstract The effect of the surface area of palm kernel shell activated carbon (PKSAC) on the properties of n-octadecane-encapsulated shape stabilized phase change material (SSPCM) for thermal energy storage (TES) application were studied. Various surface areas of the PKSAC were prepared using different amounts of H3PO4 treatment given to palm kernel shells from 0, 5, 10, 30 and 40% before the activation. The impregnation of n-octadecane into the different surface areas of PKSACs produced SSPCMs with different physico-chemical characteristics. The DSC analysis indicates that the higher the surface area of the PKSAC resulted in the higher freezing temperature due to the higher PCM loading that was encapsulated into the PKSAC pores. The results obtained from XRD, FESEM, Raman spectroscopy, TGA/DTG and leakage study indicate that the PKSAC is a good framework material for the development of n-octadecane-encapsulated SSPCM. It was also found that the surface area and porosity of the frameworks, activated carbon play an important role on the PCM loading percentage and their ability to be used as a thermal energy storage material.

Oil palm clinker is formed by burning of oil palm kernel shell and fibrous materials in boiler furnace. The clinker is no longer a bio-material that has changed to inert material likes the crushed brick. Large quantities oil palm clinkers have become a waste and caused disposal problem. It requires extra costs for handling, transportation and finding out suitable the dumping site. Research has been conducted to explore the potentiality usage of oil palm clinker as fine and coarse lightweight aggregates at Universiti Pertanian Malaysia. Mixtures of oil palm clinker concretes were designed, prepared and tested. Mechanical properties of a good mixture of tensile strength, compressive strength, modulus of elasticity, creep and shrinkage were satisfied the standard engineering codes of practices. Oil palm clicker concrete was found lighter than conventional concrete, which usually weighs between 2240 and 2400 kg m-3. The means of compressive and tensile strengths were found 30.79 and 3.34 N mm-2 respectively. In addition, the mean of modulus of elasticity was 13.024 kNmm-2. Therefore, oil palm clinker aggregate and concrete are recommended to be used in lightweight reinforced concrete structures.

A shape-stabilized composite phase change material (SCPCM) made of n-nonadecane infused by capillary forces in a compressed reduced graphene oxide-activated carbon matrix (EFB(rGOAC)-M) was prepared from oil palm empty fruit bunch. The composite exhibited improved thermal properties and was used to fabricate an SCPCM by impregnation, in which the pores of the EFB(rGOAC)-M served as the support, while n-nonadecane was the central envelope. The EFB(rGOAC)-M exhibited a specific surface area of 680 m2 g-1 and an average pore size of 22 Å. The successful infiltration of n-nonadecane into the pores of EFB(rGOAC)-M was confirmed via nitrogen gas adsorption-desorption isotherms and scanning electron micrographs. According to the differential scanning calorimeter analysis, the composite SCPCM-5 exhibited melting and freezing temperatures of 37.25 °C and 25.58 °C, respectively, and an associated latent heat value of 82.72 J g-1 and -62.22 J g-1, respectively. There was no seepage during the phase change process (from solid to liquid, as the n-nonadecane was uniformly dispersed in the pores of the carbon matrix (EFB(rGOAC)-M) and held by the capillary and the surface tension forces of the carbon matrix. This innovative, inexpensive and environmentally friendly shape-stabilized phase change material could be applied for thermal energy storage applications.
