An active heterogeneous Al2O3 modified MgZnO (MgZnAlO) catalyst was prepared and the catalytic activity was investigated for the transesterification of different vegetable oils (refined palm oil, waste cooking palm oil, palm kernel oil and coconut oil) with methanol to produce biodiesel. The catalyst was characterized by using X-ray diffraction, Fourier transform infrared spectra, thermo gravim...
In Malaysia, most of the PKC produced are from expeller extraction. Though solvent extraction is also used in the extraction of palm kernel oil but the process is costly and screw press extraction (expeller) is the rule in many palm oil processing plants. The difference in the quality of expeller PKC and solvent extracted is small, although in general expeller PKC contains more oil (4%-8%) than...
The product ion of crude palm oil and palm kernel is a complex problem due to the inf luence of processing variables and environmental factors. These processing variables inf luence the amount of crude palm oil and palm kernel losses during processing. Instead of mathematical model, fuzzy logic approach provides a simpler and easier mechanism to describe the relat ionships between the processin...
Oil palm (Elaeis guineensis) is the most productive oil bearing crop worldwide. It has three fruit forms, namely dura (thick-shelled), pisifera (shell-less) and tenera (thin-shelled), which are controlled by the SHELL gene. The fruit forms exhibit monogenic co-dominant inheritance, where tenera is a hybrid obtained by crossing maternal dura and paternal pisifera palms. Commercial palm oil produ...
An overview from the perspective of one manufacturer is provided on products that utilise either palm oil or palm kernel oil. The manufacturer is Macphie of Glenbervie while the products are of a wide-ranging nature for use in bakery, food service and food-manufacturing. Much of the discussion concerns cream alternatives on the grounds that this product-category places great demand on the type ...
Pyrolysis of palm kernel shell in a fixed-bed reactor was studied in this paper. The objectives were to investigate the effect of pyrolysis temperature and particle size on the products yield and to characterize the bio-oil product. In order to get the optimum pyrolysis parameters on bio-oil yield, temperatures of 350, 400, 450, 500 and 550 °C and particle sizes of 212–300 μm, 300–600 μm, 600μm...
Oleochemicals refer to chemicals from natural oils and fats of both plant and animal origins. However, they also include those derivatives derived from the subsequent modification of carboxylic acid group of fatty acids by chemical or biological means, and other compounds obtained from further reactions of these derivatives. Prior to 1980, about 90% of the raw materials for oleochemical industr...
Fatty hydroxamic acid derivatives were synthesized using Lipozyme TL IM catalyst at biphasic medium as the palm kernel oil was dissolved in hexane and hydroxylamine derivatives were dissolved in water: (1) N-methyl fatty hydroxamic acids (MFHAs); (2) N-isopropyl fatty hydroxamic acids (IPFHAs) and (3) N-benzyl fatty hydroxamic acids (BFHAs) were synthesized by reaction of palm kernel oil and N-...
