Abstract

Disclosed is a method for preparing an agricultural carbon by pyrolyzing, carbonizing and activating organic waste, which comprises the steps of: feeding the organic substance into heating equipment; using the heating equipment; heating the organic substance using the heating equipment, during which the organic substance is decomposed to produce carbon and a mixed gas which is discharged; at the same time when the heating equipment is heating, feeding the steam and flue gas into the heating equipment to produce the agricultural carbon after activating the carbon for a period, in which case, the steam is water steam and the flue gas is produced after burning a combustible material. The present invention also discloses a device for realizing the abovementioned method, which device at least comprises a heating chamber and a steam boiler which is used for providing the steam and flue gas and for recycling the combustible gas produced after decomposition of the organic substance.

Abstract

The present invention provides a device for biochar manufacturing. The device comprises a hopper, a rotary preheat chamber, a rotary dry distillation chamber and a cooling chamber. The rotary preheat chamber is located in a hot flue gas chamber, with one end connecting to the hopper through an incoming roller and a first screw conveyor and the other end connecting to the top of a middle hopper through an outgoing roller, used to preheat the biomass raw material; the rotary dry distillation chamber is located inside a combustion chamber, with one end connecting to the bottom of the middle hopper through a front roller and a second screw conveyor and the other end connecting to a discharge chamber through a back roller, and a burner being installed at its bottom; the dry distillation chamber is used for carbonizing the preheated biomass raw material and causing it to undergo an activation reaction with steam and flue gas to form biochar; the cooling chamber is located below the discharge chamber and is used for cooling the biochar formed through the activation reaction. The biochar manufacturing device of the present invention can use livestock manure, crop stalks, bagasse and other biomass as raw material to manufacture biochar in a low-cost and industrialized manner.

METHOD FOR TREATING SATURATED ACTIVATED CARBON

      
Application Number CN2007001620

Abstract

A method for treating saturated activated carbon comprises the following steps: A) the saturated activated carbon is dewatered so that the water content of the activated carbon is ≤25%. B) The product obtained from the step A is dried at the starting temperatures of 120ºC-150ºC. C) the product obtained from the step B is dried distilled. The dry distillation condition is that heating to 500ºC-600ºC at the rate of 4ºC-10ºC per minute and maintaining for 10-60 minutes. The organic matter on the surface and in the hole of the activated carbon is cracked, volatilized, and carbonized. D) The product obtained from the step C is activated and the activation condition is that heating to 800ºC-950ºC at the rate of 2ºC-8ºC per minute and supplying the vapor. The proportion by weight of the activated carbon and the vapor is 1:0.5-5. The activated time is 0.5-2 hours. The activated carbon may be used as the fuel after many treating processes.
