Occasionally, the bactericidal effect of the liquid of dry distillation of waste oak is the best of all.

Study on dry distillation technology of bacteriostatic fumeol by lentinus edodes' pedicel

In order to provide the theoretical basis for mining the shale oil in situ,the dry distillation experiment of the oil shale at high-temperature and high-pressure is carried out,and then the triaxial seepage experiment of the dry distillation oil shale is finished.

The oil shale dry distillation for producing shale oil started in the first half of nineteenth century in Western European countries,hereafter declined due to the development of cheaper crude oil,and then re-developed due to world oil crisis.

The yield,distillation range , elemental composition and other properties ofsolid heat carrier retorting tar from Shenfu coal were determined.

Disposal of carbonization wastewater of oil shale

This paper put forward some opinions of electrode char distributive proportion and measurement of Gray-King low temperature assay and compared it with carbonization test in aluminium retort.

According to Brazil PETROSIX technology, a retorting experimental rig was set up.

The oil shale retorting for producing shale oil started since the first half of the nineteenth century in Western European countries.

The original commentary is about typical technologies for oil shale retorting.
