Product Description

 

Biomass carbon-vapor co-production is the process of producing carbonized materials and vapor with biomass materials, in which materials are heated in an air-isolation environment to reduce content of elements other than carbon. Main structure of the plant consists of a material bin, an elevator,a feeder,a furnace stack,refractories,a rotator,a temperature detector,a PLC cabinet,a cooler,a settling chamber,a waste heat boiler,a fan,and a deduster.
The carbonization process is an integration of material carbonization and vapor production based on end gas therefrom.
Carbonization Process The carbonization process is actually a destructive distillation process at low temperature,in which materials are heated in a low-temperature and air-isolated environment to volatlize low molecular compounds, and then trigger a series of complicated physical and chemical changes in materials, which involves physical changes such as dehydration,degasification and drying.The process causes materials to discharge oxygen,hydrogen and other non-carbon substances, and recombine into substances in ordered graphite microcrystaline structure. Gaps among microcrystaline in these crystals formed with irregular hexagon carbon atomic planes are initial pores of the carbonized materials.Therefore, purposes of carbonization are changing materials into secondary pore structures adapted to activation, and rendering them with mechanical hardness required for undergoing the activation. Requirements on carbonization of materials are obtained through carbonization.
Appearance of carbonized materials shall meet requirements in dimension and shape. Inner structure of carbonized materials shall offer specific initial pores and high mechanical hardness. The carbonization process may be divided into the following sections.

working process

 

(1) Drying section at a temperature below 150C. External and internal moisture of materials evaporate in external heat,and shape of materials remains.
(2) Pyrolysis section at a temperature between 150-300 C. Materials decompose and release gaseous products (Co,Co2,H2 S,etc.),changes of chemical composition of material initiates. Pyrolysis temperature varies with specific materials, which is lower for low-metamorphic grade materials.
(3) Carbonization section at a temperature between 300-600C Polycondensation and thermolysis cause materials to separate volatile components out.
Constant temperature and heating rate are key operable conditions for carbonization process. Heating rate is critical for productive ratio of carbonized products.

A lower heating rate may prolong the duration of materials in low-temperature section,offering more options of pyrolytic reactions which break weaker bonds in molecular in initial pyrolysis, and form structures with higher thermal-stability in parallel sequential thermal polycondensation, and thus reduce volatile productive rate of pyrolysis in the high-temperature section,and achieve higher productive rate of solid carbonized products(carbonized materials).
Quality of carbonized materials output from carbonization process shall be evaluated considering volatiles content,moisture content and hardness.
Qualified carbonized materials shall be with a volatiles content of 12%-16%, a moisture content of 15%-25%,and a ball-pan hardness of 90%.
As measurements of the above indexes are time-consuming, and immediate evaluation on carbonized materials are required in on-site debugging for further adjustments on parameters,visual inspection and evaluation are acceptable. Qualified carbonized materials shall have smooth and crack-free surfaces, high hardness and uniform sections.
