Anaerobic digestion (AD) is a waste management method worldwide, that results in biogas and digestate production. The digestate remains is a potential biofertilizer but may fall short of vital nutrients required for optimal plant growth, hence, requires amendment with other biomass residues. This study was aimed at investigating the microbial quali...

Anaerobic digestion (AD) of organic wastes results in biogas and digestate production. The digestate from AD may fall short of vital nutrients required for an optimal plant growth due to feedstock quality. Thus, digestate amendment with biomass and aerobic metabolic activities becomes an essential process for nutrient enhancement. This study aimed...

This study investigated the batch co-digestion of cattle rumen content (CRC) and food waste (FW) for biogas production in different ratios (CRC:FW) to assess biogas production and process stability. The results showed that CRC and FW possess characteristics that are desirable for biogas production as seen in their respective total solids (10.85 and...

The use of wastes for biogas production has been restricted to few feedstock like cattle manure and food waste. Increasing the feedstock base for biogas production is capable of increasing the sustainability of feedstock availability. This study seeks to assess sociocultural and acceptability issues associated with the use of faecal waste (human ex...

Across different sections of life, physical and chemical sciences, differential equations which could be ordinary differential equations (ODEs) or partial differential equations (PDEs) are used to model the various systems as observed. Some types of ODEs, and a few PDEs are solvable by analytical methods with much difficulties. However, the great m...

With the increasing interest in developing alternative fuel sources to fossil fuels, biodiesel is one preferred alternative. Several researchers have proposed the use of heterogenous catalyst but it is not commercially in use yet. Recently, more attention is being paid to improvement of the energetic performance and minimising the inefficiencies in...

When hydrogen is used as a combustion fuel, there is reduced emission of greenhouse gases. One of the most economical and technically proven techniques of Hydrogen production is steam reforming (SR) of natural gas. This study covers the steady-state simulation and optimization of the SR production of Hydrogen from natural gas (methane, CH4) using A...

In this paper, MATLAB2015b was used to study the numerical simulation of the dehydrogenation of ethyl-benzene to produce Styrene. The ODE solvers used are Runge-Kutta Lower Order, Runge-Kutta Higher Order and Adams-Bashforth-Moulton. The process involves the production of styrene, toluene and benzene from ethyl-benzene at inlet temperatures 800K an...
