In this paper, a numerical simulation of the in situ retorting
of continental oil shale in Northeast China was performed.
Depending on temperature, a reduction of 81% to 96% in furan levels was possible, compared with retorting
According to the variations of the particle size, the Surface retorting
of oil shale can be classified into two categories: lump shale process and particulate shale process.
The uniformity of gas flow in each part of the retorting
zone was calculated by the same method as in literature , using Equation (1):
In case of surface retorting
, oil shale needs first to be transported to the surface by open pit or underground mining.
the limiting factor is usually heat conduction in the product," said Prof Richardson, "but this new process promotes much faster heat transfer for many products and gives impressively short process times--for example just 2.
The distribution of the heating gas in the retorting
zone and the pressure drop across the retort are responsible for heat exchange efficiency, products yield, oil quality, and the benefits of the oil shale retorting
One person operates the entire retorting
and materials handling system.
causes extensive permanent changes to surface topography as a result of mining and spent shale disposal.
In this paper, an oil shale comprehensive utilization system based on Huadian-type retorting
technique is presented.
Prior to retorting
, 2 containers in each crate are marked with the retort #, batch #, and crate #.
or sterilization process is adjacent to the primary packaging and often the end-of-line processes for many of our customers.
