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 ...

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 ...

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 ...

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 ...

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 ...

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 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 ...

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 ...

This study investigated the influence of the attainable region technique to ball milling as applied in reactor technology. Flow rate, ball filling, mill speed, ball size and mill density were varied. When each was varied, ...

A key engineering challenge is a transition to cleaner sustainable energy supply that is derived from renewable resources. Furthermore, affordable access to this modern sustainable energy services for communities in ...
