What is oil shale ash

The oil shale leaves these zones in the form of a hot shale ash (some- times called "spent shale"). Near the bottom of the retort the ash is cooled by a cold stream  Oil shale ash was added to the asphalt concrete mix at optimum asphalt content. Five ash levels, ranging from 0 to 20 percent by volume of asphalt, were used in  Based on the ash analysis, this oil shale has an inherent calcium to sulfur molar ratio of about 7.3. The operating conditions explored during combustion of the  Based on these main considerations, as a part of the study in which contribution of ash, obtained as a result of the burning of oil shale rocks in fluidized bed 

The process of extracting liquid crude oil from the ground is comparatively simple to extracting oil shale. Pressure from gases trapped in the chamber where oil is present force the crude oil to the surface. After this pressure is alleviated, the more difficult secondary and tertiary phases of oil drilling begin.

Depending on the extraction process and the amount of remaining organic matter , spent shale may be classified as oil shale coke, semi-coke or coke-ash  The inorganic part of Estonian kukersite oil shale consists of carbonates and terrigenous materials. Commercial oil shale contains 65 to 80% of inorganic matter. An experimental investigation was undertaken to study the potential use of Jordanian oil shale ash (OSA) as a raw material or an additive to Portland cement  PDF | Oil shale exploitation combined with producing huge amount of ash.

Oil shale ash was added to the asphalt concrete mix at optimum asphalt content. Five ash levels, ranging from 0 to 20 percent by volume of asphalt, were used in 

Mar 4, 2013 Oil shale is a type of rock that can be burned for energy or fuel. This ash can pollute ground, air, and water sources. Another method that can  electrodes. Oil coke, bitumen.

Combustion tests of Jordan's oil shale   60 m2 gÀ1 of carbon while class C fly ash (from low rank coals) have carbon BET surface areas comparable to oil shale semicoke organic char surface areas. The oil shale ash, recognised as burnt shale in the world nomenclature produced as a by-product during oil and electricity production is an environmentally safe  The oil shale leaves these zones in the form of a hot shale ash (some- times called "spent shale").
