Analysis of total hydrogen content in palm oil and palm kernel oil A fast and non-destructive technique based on thermal neutron moderation has been used for determining the total hydrogen content in two types of red palm oil dzomi and amidze and palm kernel oil produced by traditio-nal methods in Ghana.

An equipment consisting of an Am-Be neutron source and 3He neutron Modelling microwave heating of discrete samples of oil palm kernels. Recently, microwave MW pre-treatment of fresh palm fruits has showed to be environmentally friendly compared to the existing oil palm milling process as it eliminates the condensate production of palm oil mill effluent POME in the sterilization process.

The simulation results show that temperature of an OPK is not the same over the entire surface due to constructive and destructive interferences of MW irradiance. This implies that point measurement of temperature reading is inadequate to determine the temperature history kemaj the OPK during the microwave heating process. The simulation results also show that arrangement of OPKs in a MW cavity affects the kernel temperature profile.

The heating of OPKs were identified to be affected by factors such as local electric field intensity due to MW absorption, refraction, interference, the contact effect between kernels and also heat transfer mechanisms. The thermal gradient patterns of OPKs change as the heating continues.

The cracking of OPKs is expected to occur first in the core of the kernel and then it propagates to the kernel surface. The model is useful. Effects of de-oiled palm kernel cake based fertilizers on sole maize A study was conducted to determine the effect of de-oiled palm kernel cake based fertilizer formulations on the yield of sole maize and cassava crops.

Two de-oiled palm kernel cake based fertilizer formulations A and B were compounded from different proportions of de-oiled palm kernel cake, urea, muriate of potash and Pleurotus pulmonarius cultivation on amended palm press fibre waste.

Kinetics of palm kernel oil and ethanol transesterification. Biodiesel, an alternative diesel fuel made from meetodu sources such as vegetable oils and animal fats, has been identified by government to play a key role in the socio-economic development of Ghana. Despite this great potential and the numerous sources from which biodiesel could be developed in Ghana, there are no available data on the kinetics and mechanisms of transesterification of local vegetable oils.

The need for local production of biodiesel necessitates that the mechanism and kinetics of the process is well understood, since the properties of the biodiesel depends on the type of oil use for the transesterification process. The objective of this work is to evaluate the appropriate kinetics mechanism and to find out the reaction rate constants for palm kernel oil transesterification with ethanol when KOH was used as a catalyst.

In this present work, 16 biodiesel samples were prepared at specified times based on reported optimal conditions and the samples analysed by gas chromatography. The experimental mass fractions were calibrated and fitted to mathematical models of different proposed mechanisms in previous works. The rate data fitted well to second-order kinetics without shunt mechanism. It was also observed that, although transesterification reaction of crude palm kernel oil is a reversible reaction, the reaction rate constants indicated that the forward reactions were the most prominent.
