Sulfur oxide (SO2) and hydrogen sulfide (H2S) are considered as one of the major air pollutants in world today. In addition, high sulfur levels petroleum distillates can promote deactivation catalysts through poisoning fluidized catalytic cracking (FCC) during hydrocracking heavy to lighter ones. The presence sulfur-containing compounds process streams could cause corrosion piping fittings equipment, thereby damaging pipelines leading emissions compounds, which undesirable for mankind his...
Modeling and simulation (M&S) is a well-known scientific tool that could be used to analyze system or predict its behavior before physical construction. Despite being an established methodical in engineering, only few review articles discussing emerging topics M&S are available open literature, especially for renewable sustainable energy systems. This critically examines recent advances modeling the sector, with insights on approaches, challenges, prospects selected systems (RSES). In...
Abstract Carbon sequestration in unmineable coal seams has been proposed as one of the most attractive technologies to mitigate carbon dioxide (CO 2 ) emissions which CO is stored microporous structure matrix an adsorbed state. The adsorption process hence considered more effective methodologies environmental sciences. Thus, isotherm measurements and modelling are key important scientific measures required understanding system, mechanism, optimization coalbeds. In this paper, three renowned...
Abstract Chitinases, enzymes that degrade chitin, have long been studied for their role in various biological processes. They play crucial roles the moulting process of invertebrates, digestion chitinous food, and defense against chitin-bearing pathogens. Additionally, chitinases are involved physiological functions crustaceans, such as food digestion, moulting, stress response. Moreover, universally distributed organisms from viruses to mammals diverse including tissue degradation...
In this study, catalytic performance of nanoferrites NiFe2O4 and Ni0.3Zn0.7Fe2O4 is reported. Nickel–ferrite mixed nickel–zinc ferrite were successfully synthesized by combustion reaction using a conical reactor with production 10 g per batch. Crystallinity purity or quantitative analysis the catalyst checked X-ray diffraction energy dispersive analysis. Surface chemistry was examined via Fourier transform infrared (FTIR) analysis; N2 physisorption at 77 K conducted to obtain textural...
In the present study, waste rubber seed shell (RSS) obtained from our previous study was investigated as a plausible solid base catalyst for transesterification of esterified oil (RSO) to biodiesel. TGA, XRF, XRD, SEM, and N2 adsorption/desorption analysis (BET) were used characterize catalyst. Central composite design (CCD) employed experiments conducted influence process variables (reaction time, methanol/oil ratio, loading) on biodiesel yield. Response surface methodology (RSM) technique,...
The challenges of increasing energy demand and advanced materials for infrastructural development in developing countries have necessitated the search sustainable sources raw materials. high amount agricultural residues generated Africa owing to vast availability arable land has been an impetus solving some these challenges. Therefore, this review article provides information on beneficiation two largely residues, corncobs sugarcane bagasse, Nigeria South Africa. estimated quantities corncob...
A systematic study of the diffusion mechanism and effect mass transfer limitation during adsorption CO2 onto polyaspartamide is presented using a differential bed method, carried out in 100 × 60 40 mm packed-bed unit. The rate-limiting step where dominant was studied models. It observed that intraparticle major contributor to resistance offered transport gas molecule through polyaspartamide. behaviour polyaspartamide, based on rate parameter derived from plots adsorbed versus square root...
Acid mine drainage is an environmental problem associated with mining operations and activities. Its treatment essential to achieving sustainability. In this study, a polyethersulphone (PES) membrane infused chitosan proposed as point-of-use material for treating acid (AMD). The composite explored the synergetic effect between polymer, particularly considering of degree deacetylation (DD) on performance membrane. Chitosan was produced from chitin under various synthesis process conditions...
Amorphous silica has been produced from some agricultural wastes but with drawbacks on agglomeration challenges. In the present study, potential of maize stalk (MS) as a source nano was studied through modified sol-gel techniques, which involved acid pretreatment, calcination, leaching, modification, and post-filtration treatments. Nano particles obtained were characterized by XRD, SEM, EDS, TEM, PSA, Raman, FT-IR for morphology, elemental composition, particle size, surface chemistry....
