Power-to-chemicals processes hold tremendous potential to enable the widespread adoption of
renewable sources of energy and to open many avenues to the green hydrogen economy. These
processes will play a critical role ...
Glycerol is considered as the major waste from biodiesel production since every 1L of biodiesel
produced is accompanied by 0.1 L of glycerol by-product. Utilizing this waste as a biorefinery
feedstock will not only ...
A 2D pseudo-homogeneous fixed bed reactor model was developed using ANSYS Fluent,
based on an actual bench-scale Fischer-Tropsch reactor. The single-tube reactor had a
diameter of 0.05m, which is representative of the ...
Reduced graphene oxide (RGO) supported cobalt based catalysts with or without rhodium promotion,
Rh-Co/RGO (RCG) and Co/RGO (CG), were successfully synthesized and evaluated in both Fischer Tropsch synthesis (FTS) and ...
The industry’s great interest is to intensify the cobalt-based Fischer-Tropsch synthesis (FTS)
process by increasing the per-pass conversion and the production of long chain hydrocarbons. To
achieve this goal, it is ...
Diesel fuel has been found to contain highly concentrated organo-sulphur compounds which have bad impact economically, environmentally, and health-wise. Adsorptive desulphurization (ADS) is one of the promising processes ...
In this study, period four transition metal oxides (Zn, Cr, Mn, Co, Fe, Cu, Ni), acting as
intermediate Lewis acids, were supported on activated carbon (AC) and used in the adsorptive
desulfurization (ADS) of model and ...
With the aim of studying the reactivity of ethylene and consequently understanding and
elucidating aspects of the Fischer-Tropsch (FT) reaction mechanism, a large number of
experiments were conducted using feed gas ...
The implications of comminution practices on the planning of a typical open pit mine was investigated in this study by means of computer simulation. The objective was to assess the effects of mining costs as well as ...
Supercapacitor is the best potential candidate of the energy storage system due to the
superior charge or discharge efficiency, high power density (>10 kW kg-1), and long cycling life. Porous carbon materials as the ...
The global community has accepted Fischer Tropsch synthesis as one of the sustainable pathways to transportation fuels and chemicals due to the ever-depleting reserves of fossil fuels and its detrimental impact on the ...
This study described an alternative approach for flotation circuit optimization using a mathematical programming technique. Mathematical formulation resulted in mixed integer nonlinear programming problem. Experimental ...
Abstract
This paper presents the findings of an investigation into the influence of green-synthesized nano-TiO2 on the characteristics of wood ash (WA) cement mortar. Mortar specimens were prepared by partial ...
Water is the source of life because all living organisms cannot survive without it and it is the
most important liquid in the ecosystem hence protecting water resources and ensuring water
quality should always be an issue ...
Heterojunctions were generated between tungsten trioxide and tetraphenyl porphyrin with
reduced graphene oxide or exfoliated graphite support for mineralisation of acid blue 25
dye under visible light radiation. Moreover, ...
This dissertation investigates the level of acid‐resistance of concrete degradation.
Concrete specimens obtained from four mixtures (M1, M2, M3 and M4) were
prepared with calcareous, siliceous ...
The eco-friendly alternatives use is increasing momentum in a conscious effort
towards sustainability. In this regards, the relevance and the economic value of
using copper slag as a concrete aggregate are explored in ...
The objective of this study was to improve the operation of the classical semiautogenous and ball milling circuit also known as the SABC circuit. In order to
achieve this goal, the challenges around this circuit were ...
Kansanshi mine sulphide ore circuit did not achieve target flotation recovery in
2016, hence it was deemed necessary to carry out a research aimed at optimizing
this circuit. The objective of the research was to optimise ...
In this study, the effect of speed was investigated on the breakage rate of UG2
platinum ore in a batch mill of 5 dm3 and 175 mm internal diameter. One size fraction
method was carried out to perform the experiment. Five ...
