Embodiment 1

[0030] A method for preparing fragrant charcoal by using semi-coke after upgrading lignite, uniformly mixing semi-coke powder and coke powder, then adding a molding binder and molding it into a plum-shaped rod to obtain the fragrant charcoal; wherein, the semi-coke powder and In the mixture of the two coke powders, the mass percentage of the semi-coke powder is 70%, and the coke powder is 30%; the fixed carbon content in the coke is not less than 80%. The amount of molding binder is 6% of the mass of the mixture of semi-coke powder and coke powder.

[0031] The diameter of semi-coke powder is not greater than 3mm, and the diameter of coke powder is not greater than 1mm.

[0032] The semi-coke has a fixed carbon content of not less than 60%, a volatile matter content of 15±1%, ash content of 15-20%, and a particle size diameter of 0.1mm-60mm.

[0033] Described binding agent obtains as follows:

[0034] First take the material according to the following percentage by weight: ...

Embodiment 2

[0044] A method for preparing fragrant charcoal by using semi-coke after lignite upgrading, uniformly mixing semi-coke powder and coke powder, then adding a molding binder and molding it into an oval block to obtain the fragrant charcoal; wherein the semi-coke powder In the mixture with the coke powder, the mass percentage of the semi-coke powder is 80%, and the coke powder is 20%; the fixed carbon content in the coke is not less than 80%. The amount of molding binder is 7% of the mass of the mixture of semi-coke powder and coke powder.

[0045] Others are the same as embodiment 1.

Embodiment 3

[0047] A method for preparing fragrant charcoal by using semi-coke after lignite upgrading, uniformly mixing semi-coke powder and coke powder, then adding a molding binder and molding it into an oval block to obtain the fragrant charcoal; wherein the semi-coke powder In the mixture with the coke powder, the mass percentage of the semi-coke powder is 75%, and the coke powder is 25%; the fixed carbon content in the coke is not less than 80%.

Abstract

The invention belongs to the technical field of wood charcoal preparation, and particularly relates to a method for preparing spicy carbon by utilizing semi-coke. The method comprises the following steps: uniformly mixing the semi-coke powder with the coke powder; and adding a forming adhesive to the mixture and forming to obtain the spicy carbon, wherein in the mixture of the semi-coke powder and the coke powder, the semi-coke powder is 70%-80% (in percentage by mass), the coke powder is 20%-30%, and the content of fixed carbon in the coke is not lower than 80%. The spicy carbon obtained by the method disclosed by the invention is excellent in quality, not only can be used for replacing the wood charcoal to reduce the tension in wood charcoal supply, but also can be used for improving the additional value and the efficient utilization of the semi-coke.

Description

technical field [0001] The invention belongs to the technical field of charcoal preparation, in particular to a method for preparing fragrant charcoal by using semi-coke. Background technique [0002] Fragrant charcoal refers to the charcoal used for barbecue, which becomes charcoal after the wood is separated by thermal junction to release dust. Fragrant charcoal is an industrial raw material, and it is also the main raw material needed for civil heating and barbecue food in daily life, and is in great demand. For example, a barbecue pit needs more than half a ton of charcoal to meet the demand every month. Due to restrictions on logging, the price of charcoal has risen to 6-10 yuan per kilogram, which is expensive and not easy to buy. [0003] The product obtained by extracting volatile matter from lignite in dry distillation (to produce chemical raw materials such as methanol and diethylene ether) has a fixed carbon percentage of more than 60%, a volatile matter of abou...
