Problems solved by technology

The main reason is that most retort furnaces cannot process oil shale with small grains below 10mm, and are only suitable for processing shale with grains above 10mm. waste
However, some methods of refining small-grained oil shale below 10 mm in size by heating with solid heat carrier have complex processes, huge investment, and unstable operation.

Abstract

The invention discloses a 10mm-below granular oil shale cold-pressing sphere and a method for oil refining by adopting the same. The oil shale cold-pressing sphere is prepared by adding adhesives with weight percentage of 8-15 percent into 10mm-below granular oil shale, wherein the adhesives comprise the following components in percentage by weight: 10-30 thousandth of humic acid calcium, 20-40 thousandth of kaolin, 0.5-1 thousandth of magnesium phosphate, and the balance water. The method comprises the following steps of: feeding the oil shale cold-pressing sphere into a gas retort, cushioning and falling through two layers of baffles, increasing steps of heat supplying carried out by a central heat supply device in the gas retort and the like so as to carry out dry distillation to obtain an oil gas mixture, and carrying out oil refining through an oil recovery system and the like. The oil shale cold-pressing sphere has good resistance to high temperature and high mechanical strength, and is not easy to crush; the production period of the gas retort is effectively prolonged, and the working efficiency is improved; and the cold-pressing sphere is adopted for oil refining, so that the co-combustion amount is high, the heat stability is good, the hot and cold strength is high, the dry distillation effect is good, the oil extraction rate is higher, the pollutant emission is less, the space is saved, the secondary pollution is avoided, and the cost is low.

Description

[0001] Technical field: [0002] The invention relates to small-grained oil shale cold-pressed balls less than 10 mm in size and a method for refining oil using the same, and belongs to the technical field of comprehensive utilization of oil shale. Background technique: [0003] At present, most of the small-grained oil shale below 10mm is used as a low calorific value fuel for coal blending for combustion and power generation, and there is no use of small-grained oil shale below 10mm for carbonization and refining. The main reason is that most retort furnaces cannot process oil shale with small grains below 10mm, and are only suitable for processing shale with grains above 10mm. waste. However, some methods of refining small-grained oil shale below 10mm in size by heating with a solid heat carrier have complex processes, huge investment, and unstable operation. Invention content: [0004] The object of the present invention is to overcome the deficiencies of the above-m...
