Abstract
The invention relates to a process for preparing bio-charcoal by a zinc borate flame retarding method. The preparation process comprises the following steps of: mixing lotus rod powder according to different mass ratios; then, adding deionized water and uniformly mixing; after a period of soaking, carbonizing and activating in a Muffle furnace for 40 minutes; washing the carbonized sample by use of hydrochloric acid and tap water sequentially till the pH is stabilized at 6.5-7.0; and drying. According to the bio-charcoal prepared by the invention, the environmental pollution in the preparation process of the bio-charcoal can be reduced, the bio-charcoal yield is improved, the surface oxygen content of the bio-charcoal is remarkably increased, and the absorption effect of the bio-charcoal to nickel is greatly improved.
Description
One, technical field
The present invention relates to a kind of phyteral charcoal preparation technology, belong to the charcoal preparing technical field.
Two, background technology
The phyteral charcoal refers to that biomass under the anoxia condition handle the charcoal that makes through high temperature carbonization, is widely used in carbon dioxide fixation, drainage of soil system enhancement, greenhouse gases and seals, strengthens aspects such as soil fertility, absorb polluted matter up for safekeeping.
Zinc borate is a kind of cheapness, easily obtain, the efficient flame-retarding agent of nontoxic, high thermal stability, good dispersity.Under the comparatively high temps, zinc borate can form watertight layer on precursor, stops the surperficial inflammable gas of precursor and the release of volatiles.
For the preparation of charcoal mainly with phosphoric acid as activator, probe into the influence of differing materials, different pyrolysis temperature, different pyrolysis time emphatically to charcoal, at present, do not find to prepare as activator the report of charcoal as yet with zinc borate.
Three, summary of the invention
The present invention has provided the method for preparing charcoal with the zinc borate of tool flame retardant properties as activator: the zinc borate by mass ratio interpolation different mass in the lotus bar makes through pyrolysis charring at a certain temperature.
The present invention makees activator with zinc borate, and to prepare the technology of biomass charcoal as follows:
(1) lotus bar powder is pressed mass ratio 1:1～4:1 and mixes with zinc borate, add the deionized water mixing and stirring again after, 105 the degree under the dipping 8 hours;
(2) above-mentioned dipping is good sample placed the retort furnace carbonization-activation 40 minutes;
(3) sample that charing is good is earlier with behind the salt acid elution, again with the tap water washing, is stabilized at 6.5～7.0 o'clock to pH, dries, and promptly makes charcoal.
The present invention with zinc borate and lotus bar mixed charcoal, can reduce in the charcoal preparation process the pollution of environment, the charcoal yield improves, the charcoal content of surface oxygen significantly increases, and significantly improves the adsorption effect of charcoal to nickel.The present invention does not contrast with not adding zinc borate, and prepared charcoal yield improves 15%～25%; Content of surface oxygen increases by 10%～20%; Adsorptive capacity to nickel increases by 3～10 times.
Four, embodiment
Embodiment 1
The lotus bar powder of particle diameter 0.45～1.0mm is pressed mass ratio 1:1 zinc borate mix, added after the deionized water mixing and stirring under 105 degree dipping 8 hours, the dipping sample places retort furnace in 300 degree carbonization-activation 40 minutes down.The sample that charing is good is first with washing with tap water behind the hydrochloric acid, and to pH=6.5～7.0, oven dry promptly makes charcoal.
Embodiment 2
The lotus bar powder of particle diameter 0.45～1.0mm is mixed with zinc borate with mass ratio 2:1, added after the deionized water mixing and stirring under 105 degree dipping 8 hours, the dipping sample places retort furnace in 350 degree carbonization-activation 40 minutes down.The sample that charing is good is first with washing with tap water behind the hydrochloric acid, and to pH=6.5～7.0, oven dry promptly makes charcoal.
Embodiment 3
The lotus bar powder of particle diameter 0.45～1.0mm is mixed with zinc borate with mass ratio 4:1, added after the deionized water mixing and stirring under 105 degree dipping 8 hours, the dipping sample places retort furnace in 400 degree carbonization-activation 40 minutes down.The sample that charing is good is first with washing with tap water behind the hydrochloric acid, and to pH=6.5～7.0, oven dry promptly makes charcoal.
Claims (1)
1. the fire-retardant legal system of zinc borate is equipped with charcoal technology, it is characterized in that this preparation technology is as follows:
(1) lotus bar powder is pressed mass ratio 1:1～4:1 and mixes with zinc borate, add the deionized water mixing and stirring again after, 105 the degree under the dipping 8 hours;
