The heterogeneity and local distribution of elements are established as a result the study nonferrous metals composition domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc up to 1% aluminium. Metals mainly concentrated in granules three types: zinc-based, copper-based copper–zinc alloy, i.e., brass. phase these granule types their structure determined. Zi...

Magnesium alloys, known as a “21st-century green engineering material”, are widely used in many fields, including during the production and consumption of magnesium alloys die-casting products such AZ91D, AM50, AM60B. In addition, large amount waste is generated, which not only pollutes environment but also wastes secondary resources. Hereby, we reported vacuum gasification—directional condensa...

It is well known that the capacity of crude distillation units in any refinery reflect itself, and why because we consider these first stage all other such as vacuum distillation, hydrotreating, reforming, catalytic cracking, others depend on them. So devoted our effort to keep work with high performance efficiency.
 The purpose this develop Daura oil refinery, rise their level detect were...

Petroleum heavy vacuum gas oil (HVGO) containing 10 wt.% of petroleum wax was hydrocracked at 390–430 °C and under the pressure 18 MPa over a Ni W/amorphous silica-alumina catalyst in continuous-flow fixed-bed reactor. The hydrocracking reference feed (neat HVGO) carried out same reaction conditions. physico-chemical properties primary products obtained via laboratory atmospheric-vacuum distill...

     Essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on GC-MS analysis, in ...
