Drying and Particle Size Characteristics of Danta (Nesogordonia papavereria) and Hard Cross (Vitex doniana) Wood Sawdusts at Different Temperatures.

The drying and particle size characterization of Danta (Nesogordonia papavereria) and HardCross (Vitex doniana) hardwood sawdusts were investigated at temperatures 80 ºC, 90 ºC and105 ℃. The experimental drying data were modeled using eighteen existing drying models.The results showed that the modified Henderson and Pabis model offered the best fit to thedrying curves of Danta and Hard Cross sawdusts. The experimental data obtained from theparticle size distribution of both the samples we...

Production of Soy-Yoghurt by Fermentation of Soymilk with Lactobacillus Isolated from Nunu

The production of soy-yoghurt by fermentation of soymilk with lactobacillus isolated from nunu (a Nigerian indigenous fermented cow-milk) was studied. Soymilk was extracted from whole and dehulled soybean seeds and pasteurized. The fermentation was carried out with both the isolate from nunu and yoghurmet (a commercial yoghurt starter culture of Streptococcus thermophilus and Lactobacillus bulgaricus) as control. The percentage of soymilk inoculated was 70%, 80% and 100% of the broth. Soy-yog...

DETERMINATION OF REMOVAL EFFICIENCY OF METHYLENE BLUE FROM AQUEOUS SOLUTION USING CHEMICALLY ACTIVATED CARBON PRODUCED FROM MANGO SHELL

ABSTRACTThe presence of methylene blue (MB) in wastewater is a major concern in the environment due to its low biodegrability and harmful effect on man. The treatment of effluent containing such dye is important where adsorption on activated carbon (AC) produced from agricultural waste is of great choice. Optimization of the removal efficiency of MB from aqueous solution onto AC prepared from mango shell was investigated. The AC was prepared from mango shell, activated with BaCl2 at I.R (0.03...

Production of MES by transesterification of castor oil

AbstractPetroleum based detergents are neither soluble nor biodegradable; they are so stable such that when they flow into the soil, sewer or surface waters, they remain unchanged, resisting conversion into less complex and more soluble substances. In this work methyl ester sulphonate (MES) was produced by transesterification followed by sulphonation of ricinoleic acid, a main constituent of castor oil. A detergent was produced from transesterification followed by sulphonation of castor oil a...

Cryogenic Science And Engineering

   ABSTRACTThis report is intended for a general insight into cryogenics. Different individuals may have faint ideas about what cryogenics are as much is not known here in Nigeria about what cryogenics are and this report work clearly gave a deeper knowledge of cryogenics     Chapter one gives a brief history of cryogenics and the various cryogenic temperatures that have been achieved since 1800 to 1965. Chapter two gives a general knowledge of the fundament...
