Bituminous sands are one of the main sources alternative energy. However, limited application this method is associated with environmental and technical problems arising from extraction oil bituminous deposits. In paper, authors propose a new environmentally friendly technology based on nanoreagents for oil. Keywords: The rock, production, method, reagent, reservoir water, washing liquid.

Belt and King (1945) studied the tissue reactions produced in animals by selected dusts from South Wales coal mines, and found that clean coal (low ash coal fraction containing 99% coal) produced only minimal fibrosis (grade 1) with simple foreign body reaction in 250 to 500 days. In experiments with high ash coal fractions which contained from 37 to 66% coal and about 1 to 3% quartz, the rest ...

Moisture damage to bituminous pavement occurs via several mechanisms, and appears in diverse forms such as blistering, stripping, and disaggregation. Blistering is a fulminating phenomenon in which the trapped moisture evaporates and upheaves the pavement surface layer within a few hours as a result of so-called blistering heat. In contrast, stripping and disaggregation are types of internal ch...

Investigations into the cause and control of the production of sulfuric acid in effluents of coal mines, and the effects of such effluents upon streams were begun in 1946.1 Working and abandoned mines of Western Pennsylvania alone contribute an estimated million tons of sulfuric acid per year to the drainage area of the Ohio River. A field survey of mine drainage and receiving streams was inaug...

The formation of sulfur trioxide (SO(3)) in coal-fired utility boilers can have negative effects on boiler performance and operation, such as fouling and corrosion of equipment, efficiency loss in the air preheater (APH), increase in stack opacity, and the formation of PM(2.5). Sulfur trioxide can also compete with mercury when bonding with injected activated carbons. Tests in a lab-scale react...

Many bituminous coal mine effluents contain, along with other ions, high concentrations of ferrous iron. This is brought into solution by sulfuric acid produced by the oxidation of sulfuritic material, possibly iron sulfides in part, occurring with bituminous coal (Leathen et al., 1952). The ferrous iron is oxidized by bacteria to the ferric state at a more rapid rate than can be accounted for ...

The paper presents results of sensitivity analysis to crack propagation of a pavement bituminous layered structure using the Finite Element Method (FEM) and Artificial Neural Networks (ANN). The performed preliminary study determined stresses and displacements in the pavement layer system. The pavement structure consisting of asphalt layers, a base layer, subbase and subgrade layers was analyze...

The adsorptive capacity of powdered activated carbon (PAC) is related to the size of the target adsorbate compared with the quantity of pores with sufficient pore diameter into which the adsorbate may diffuse (i.e., the effective internal surface area). The adsorptive capacity of PACs are commonly characterized using aqueous-phase indices such as iodine (I2), methylene blue (MB), p-nitrophenol ...

Abstract Mercury (Hg) contamination has become a serious threat to ecosystems. Amelioration technology for soil is expected control the specific interactions between N in ex-gold mining contaminated with Hg. This research aimed analyze interaction of Hg-N on ameliorated sub-bituminous coal and activation 10% NaOH. The experimental design used this study was Completely Randomized Design three re...
