Description
Technical field
The invention belongs to macromolecule chemical industry technical field, be specifically related to a kind of bio-modification ramee CMSCH4 Concentrate first
Alkane carbon molecular sieve.
Background technology
Carbon molecular sieve (Carbon Molecular Sieve, CMS) is broadly the one having nano level superfine micropore
Nonpolar carbonaceous absorption material, is the activated carbon of micropore distribution uniform in the narrow sense, because it is made up of with crystallization charcoal amorphous carbon,
So the pore structure of carbon molecular sieve is the most flourishing, and there is the surface character of uniqueness.Because the wedge shape micropore of CMS with inhaled
Attached molecule diameter is close, and major part is effective apearture, and has the spy adjusting CMS pore size according to molecular size
Point, thus there is the ability of screening molecule.Pore structure and stable chemical property that CMS is unique make it at chemical industry
In be widely used, additionally, also obtain extensively in fields such as the production of nitrogen hydrogen, waste water process, environmental conservation, military and national defense, canister respirators
General application.
The raw material preparing carbon molecular sieve is a lot, originates the widest.In theory can be by different original materials through different
Preparation technology, obtains the carbon molecular sieve that pore radiuses and distribution is different.Experiment shows, low ash content, high carbon content and height are waved
Send out the raw material divided relatively to be suitable for preparing high performance carbon molecular sieve.
Prior art is disclosed the method preparing carbon molecular sieve by plurality of raw materials, but with ramee as primary raw material
Report also do not have, this is because ramee do not meet the requirement of low ash content, high carbon content and high volatile.
A lot of gases containing methane, such as coal mine mash gas, biogas and rubbish landfill gas, containing substantial amounts of nitrogen, titanium dioxide
The gas that carbon, oxygen etc. are useless or harmful so that it is utilization ratio is low or is difficult to work with, in order to expand the purposes of this kind of source of the gas and carry
Its utilization ratio high, often needs to carry out concentration.In process of coal mining, pump out a large amount of device in Gas from mine, owing to being mixed into
Large quantity of air, φ (CH4) only about 20%, even below 5%, the coal bed gas of this low concentration contains substantial amounts of nitrogen and meeting
Bring the oxygen of explosion danger.For a long time, because of various reasons such as economy, technology, environmental consciousnesses, a large amount of low concentration coal-bed gas because of
Cannot utilize and be discharged in air, owing to the greenhouse effect of methane is CO221 times, the biggest to environmental hazard.Exploitation
Methane concentration is utilized by advanced technology, is the important channel reducing its discharge.
