Briquette material containing low-order coal and biomass particles
A technology of biomass pellets and low-rank coal, which is applied in the fields of biofuel, special form dry distillation, petroleum industry, etc., can solve the problems of low utilization of tamping coke ovens, inability to realize large-scale application of low-rank coal and biomass, etc. It is easy to push coke, not easy to pulverize, and to improve oil and gas production.

Embodiment 1
[0033] (1) After bundling the straw with a water content of 17wt%, press it under 5Mpa to a density of 1.2g / cm 3 Particles, spare;
[0034] (2) Mix the sub-bituminous coal and the organic binder with the particulate matter of the step (1) to form a low-rank coal-type coal seam raw material for subsequent use;
[0035] Among them, the G value of sub-bituminous coal is 45, and the volatile matter content is greater than 40%. The organic binder is coal tar pitch with a dry distillation weight loss of 45% at 850°C in the absence of air, and its softening point is 105°C; In the coal-type coal seam raw material, in terms of mass, the addition of particulate matter is 20wt% of the mass of low-rank coal-type coal seam raw material, and the addition of organic binder is 40wt% of the quality of sub-bituminous coal;
[0036](3) Using tamping equipment to tamp and shape the pulverized 1 / 3 coking coal to form a non-low-rank coal-type coal seam, and add the low-rank coal-type coal seam raw...
Embodiment 2
[0040] (1) After bundling the straw with a water content of 15wt%, press it under 22.5Mpa to a density of 1.3g / cm 3 Particles, spare;
[0041] (2) After the sub-bituminous coal and the organic binder are pulverized together, they are mixed with the particulate matter of step (1) to form a low-rank coal body raw material, which is set aside;
[0042] Among them, the G value of sub-bituminous coal is 40, and the volatile matter content is 50%; the organic binder is petroleum pitch with a dry distillation weight loss of 40% at 850°C in the absence of air, and its softening point is 120°C; In the coal body raw material, by mass, the added amount of particulate matter is 35wt% of the mass of the low-rank coal bulk raw material, and the added amount of the organic binder is 5wt% of the mass of the sub-bituminous coal;
[0043] (3) Use tamping equipment to tamp the pulverized coking coal to form a non-low-rank coal-type coal seam, and add the low-rank coal-type coal seam raw materia...
Embodiment 3
[0047] (1) After baling the straw with a water content of 13wt%, press it under 40Mpa to make a density of 1.4g / cm 3 Particles, spare;
[0048] (2) pulverizing lignite and organic binder together with the particles in step (1) and mixing to form low-rank coal body raw material for subsequent use;
[0049] Among them, the G value of lignite is 0, and the volatile content is 48%; the organic binder is high-temperature petroleum asphalt with a dry distillation weight loss of 42% at 850°C in the absence of air, and its softening point is 125°C. The fixed carbon content in the high-temperature petroleum pitch is 30%, and the carbon-to-hydrogen ratio is 8; in the raw material of the low-rank coal body, in terms of mass, the amount of particulate matter added is 30wt% of the mass of the raw material of the low-rank coal body, and the organic binder The addition amount is 22.5wt% of lignite quality;
[0050] (3) Using tamping equipment to tamp and shape the pulverized 1 / 3 coking coa...
