Problems solved by technology

However, due to the low strength of kerogen shale raw ore, in the process of mining and crushing and screening, 20% of the total particles with a particle size of ≤3mm are produced, and these particles cannot directly enter the carbonization furnace for carbonization. It is used internally for non-oil production, which greatly increases production costs; and most companies directly discard this part of oil shale particles, which not only wastes resources, but also pollutes the environment

Embodiment 1

[0008] Example 1 A method for pelletizing oil shale particles

[0009] The steps are as follows: Take oil shale particles (particle size ≤ 3mm), add 2% carboxymethyl cellulose of the total weight of the oil shale particles, mix them evenly, and press them into a ball in a ball press. The strength of the product is 60kg / cm 2 .

Embodiment 2

[0010] Example 2 A method for pelletizing oil shale particles

[0011] The steps are as follows: Take oil shale particles (particle size ≤ 3mm), add 3% of the total weight of the oil shale particles, mix them evenly, and form balls in a ball press. The strength of the product is 64kg / cm 2 .

Embodiment 3

[0012] Example 3 A method for pelletizing oil shale particles

[0013] The steps are as follows: Take oil shale particles (particle size ≤ 3mm), add 1.5% of the total weight of the oil shale particles with an organic binder, mix them evenly, and press them into a ball in a ball press. The strength of the product is 70kg / cm 2 .

[0014] The organic binder is a mixture of carboxymethyl cellulose and unsaturated polyester resin in a weight ratio of 1:2.

[0015] The product is made into oil in a dry distillation kettle, and the semi-coke in the dry distillation kettle after oil making is tested. The test results are shown in Table 1. Take samples of different forms after dry distillation for testing. Among them, semi-coke (complete) refers to the spherical and complete shale balls obtained after dry distillation; semi-coke (fragments) refers to the spherical shale balls obtained after dry distillation and crushed into several pieces, and the fragments are taken; semi-coke ( Broken n...

Abstract

The invention relates to a balling method for oil shale particles. The technical scheme adopted by the invention is as follows: weighting oil shale particles, adding an organic adhesive which accounts for 1-2wt% of the oil shale and / or an inorganic adhesive which accounts for 1-3wt% of the oil shale into the crushed oil shale, mixing evenly and balling the mixture in a ball machine. The organic adhesive is one or both of carboxymethyl cellulose and unsaturated polyester resin; and the inorganic adhesive is one or a mixture of more of light burned magnesium oxide powder, quick lime, bentonite and portland cement. Compared with the oil shale raw ore, the oil shale ball prepared by the method is characterized in that shale oil is prepared in a retort and the prepared heavy oil has the same oil quality. The waste oil shale particles of which the particle size is no more than 3mm are fully utilized, thus resources can be saved and the environment can be protected; and the quality of the prepared shale oil meets the national standard.

Description

technical field [0001] The invention relates to a method for reusing discarded kerogen shale granules and powder to save resources. Background technique [0002] Oil shale is a mineral resource with abundant reserves but not yet widely utilized, and is currently being developed. Oil shale can not only extract fuel oil, but also refine synthetic gas and chemical raw materials. Its by-products can be used as fuel for circulating fluidized bed boilers, and the slag after boiler combustion can also be used to make ceramic tiles and building materials. However, due to the low strength of kerogen shale raw ore, in the process of mining and crushing and screening, 20% of the total particles with a particle size of ≤3mm are produced, and these particles cannot directly enter the carbonization furnace for carbonization. It is used internally for non-oil production, which greatly increases the production cost; and most companies directly discard this part of oil shale particles, whic...
