Embodiment 1

[0129] Example 1: Using Xinjiang coal samples to prepare multi-component slurry for the production of syngas

[0130] The Xinjiang coal raw material pre-crushed to ≤20mm enters the storage bin 1 and then is sent to the mill 9 through the weighing feeder 5 .

[0131] The present embodiment selects ball mill parameter as follows:

[0132]Specification Φ3200×4700mm, speed 17.42r / min, power 650Kw, maximum steel ball loading capacity 44t, steel ball press Do the grading.

[0133] The additives used in this example are sodium polystyrene sulfonate produced and sold by Tianjin Dagang Hongli Dye Chemical Factory and nonylphenol polyoxyethylene ether produced and sold by Nanjing Nanda Surface and Interface Chemical Engineering Technology Research Center Co., Ltd. The mixture prepared in a weight ratio of 1:2 was prepared into a 25wt% aqueous solution with water. The prepared additive solution is sent into the storage tank 7, and the equipped agitator performs continuous stirring,...

Embodiment 2

[0147] Example 2: Preparation of multi-component slurry for producing syngas with Ningxia coal samples

[0148] Adopt the same mode as embodiment 1 to carry out, but difference is as follows:

[0149] The Xinjiang coal raw material pre-crushed to ≤15mm enters the storage bin 1 and then is sent to the mill 9 through the weighing feeder 5 .

[0150] The present embodiment selects ball mill parameter as follows:

[0151] Specification Φ2400×8000mm, speed 20.4r / min, power 570Kw, maximum loading capacity of steel balls 36t, steel balls by Do the grading.

[0152] The additives used in this embodiment are acrylic acid, methyl acrylate, and acrylamide produced and sold by Zibo Dongfang Polymer Co., Ltd., and a mixture prepared according to acrylic acid: methyl acrylate: acrylamide = 1:2:1, use water It is prepared as a solution with a concentration of 25 wt%.

[0153] The pH regulator used in this embodiment is 40wt% sodium hydroxide aqueous solution, and the configured pH re...

Embodiment 3

[0163] Example 3: Preparation of multi-component slurry for production of synthesis gas with Inner Mongolia coal blending coal samples

[0164] Adopt the same mode as embodiment 1 to carry out, but difference is as follows:

[0165] The present embodiment selects ball mill parameter as follows:

[0166] Specification Φ2700×4500mm, speed 20r / min, power 430Kw, maximum loading capacity of steel balls 50t, steel balls press Do the grading.

[0167] The additive used in this example is prepared by using polysodium p-styrene sulfonate produced and sold by Xinyi Jingwei Technology Co., Ltd. and nonylphenol polyoxyethylene ether produced and sold by Xuzhou Chengzheng Fine Chemical Co., Ltd. in a weight ratio of 4:5. The mixture is used in an amount of 0.5% by weight of dry coal, and is prepared into a solution with a concentration of 25% by weight.

[0168] The pH regulator used in this embodiment is 40wt% sodium hydroxide aqueous solution, and the configured pH regulator soluti...

Abstract

The invention relates to a preparation method of multi-element slurry used for producing synthesis gas and also relates to the multi-element slurry by adopting the method. The method comprises the steps as follows: material containing carbon and hydrogen, additive, pH regulator and fluxing agent are adjusted by given values; all material feeding lines are provided with a detecting and measuring device respectively so as to carry out the online detection of the material feeding quantity, send the detected signals to a control system and reset all material feeding quantities in combination with characteristics such as consistency, composition and the like of the grinder slurry till the prepared slurry meets the requirement of a synthesis gas production system. The multi-element slurry prepared by the method achieves the conditions of 58-70wt% of consistency of fixed matter, less than 1500mPa.s of viscosity, less than 200 mesh of granularity and 30-60wt% of grains, the quality is stable, the conveying and gasifying are easy to be carried out and the method has obvious economical benefits.

Description

【Technical field】 [0001] The invention relates to the technical field of coal chemical industry, more specifically, the invention relates to a preparation method of multi-component slurry for producing synthesis gas, and relates to the multi-component slurry obtained by the method. 【Background technique】 [0002] Coal and oil and gas resources are non-renewable biological fossil resources with limited geological reserves. With the rapid development of the national economy, the consumption of resources is increasing day by day, and the pollution caused is also becoming more and more serious. In addition, natural resources are not fully utilized, so energy saving and consumption reduction Environmental protection issues have been paid more and more attention by people. [0003] my country's coal is rich in oil and gas is scarce, and energy problems are becoming more and more prominent. Coal-based pulping technology is the best and effective way to solve the gap formed by my co...
