While biodiesel has potential in resolving current energy crisis, its production is hampered by both feedstock and catalyst availability. The aim of this study to investigate the from waste vegetable oil (WVO) characterised high free fatty acid (FFA) as with heterogeneous catalysis via transesterification reaction. used was obtained eggshell calcined at 800 °C. properties were assessed using XRD, XRF, BET SEM. prepared have large pore diameter 91.2 Å surface area 30.7 m2 g−1. optimisation...
Biomass fuel properties determine the choice of agricultural waste to be used in production briquette for industrial and domestic usage. Compaction these agro-wastes would add more values their bulk handling, conveyance storage properties. This work determined effect different binders with varying concentrations applied die pressures on some physical from carbonized corncob. Cassava starch, corn starch gelatine at three 10, 20 30% wt/wt were as briquettes predetermined compacting pressure...
Future production of chemicals (e.g., fine and specialty chemicals) in industry is faced with the challenge limited material energy resources. However, process intensification might play a significant role alleviating this problem. A vision through multifunctional reactors has stimulated research on membrane-based reactive separation processes, which membrane catalytic reaction occur simultaneously one unit. These processes are rather attractive applications because they potentially compact,...
This study characterised and adjusted certain production process parameters (pH, C/N ratio temperature) critical to increasing the efficiency, stability sustainability optimise biogas yield.

Microbial analysis also performed using standard procedures on substrate digestates set-up. Physical chemical pre-treatments were done substrates ensure favourable...
This study focused on the production of biodiesel via transesterification refined soybean oil obtained locally. Sodium hydroxide was used as alkali catalyst and methanol (as alcohol) in process due to its low cost. The methanol-to-oil molar ratio maintained at 6:1. effect reaction temperature with time loading were studied. varied 30, 40, 50, 60 70 oC; 0.5 1.0% weight oil, respectively. After fatty acid methyl esters [FAMEs (biodiesel)] conversion found rise an increase also but no...
ABSTRACT This study investigated production of biodiesel from oil seeds Jatropha curcas, obtained in Nigeria, with a view to encouraging the cultivation plant Nigeria and providing motivation for development this feedstock. Also effect oil-to-alcohol molar ratio on Nigerian curcas was confirming established base case. A maximum yield fatty acid methyl esters (FAME) 87% at 333 Kelvin, 1:6 1wt% NaOH catalyst concentration. The physical properties BD met ASTM standard D-6751. Consequently,...
This study aimed at comparing the effect of various carbon sources with a fixed nitrogen source for syntheses rhamnolipid biosurfactant using strain Pseudomonas aeruginosa. The used were glycerol, glucose and waste cooking oil (WCO), benefit utilising wastes. characterized microbial was obtained from Microbiology Department Obafemi Awolowo University, Ile-Ife. It grown on surface culture before inoculation into production culture. Each media sterilized 121 °C, 15 psi min cooled inoculation....
As a follow-up to our previous study on the transesterification of Nigerian Jatropha curcas oil into Biodiesel using homogenous catalysis, kinetic reaction is hereby presented. The revealed that rate formation biodiesel can be increased by increasing temperature and alcohol molar ratio. optimum condition was established 60°C (reaction temperature) 1:6 (oil ratio). Accordingly, highest yield obtained from homogeneously catalyzed (JC) 86.61% w/w at with ratio 1:6. Furthermore, also conversion...

The study focused on Nigeria's polyurethane (PU) production process as a test case. Though it is currently insignificant when viewed from global perspective, PU in Nigeria not eco‐friendly. Traditionally, produced by reacting petro‐based polyol with poly‐isocyanate, which made amines and phosgene are imported into the country. These two materials detrimental to human health environment, indicating that industries need re‐examine their inputs for environmental compliance. objective of this...
