Description
Technical field
The invention belongs to catalysis technical fields, are related to a kind of suitable for smokeless catalytic coal gasifaction catalyst and its preparation side
Method.
Background technology
The utilization of coal in China is based on directly burning, and not only energy utilization rate is very low, but also causes dust, acid rain, big
Measure greenhouse gases CO2Pollution problems, the Coal Gasification Technologies such as discharge play an important role in terms of efficient, clean utilization coal resources,
But traditional coal gasification course reaction temperature is high, generates gas purification difficulty, energy consumption is big, to equipment requirement height.
Anthracite (English name anthracite) is commonly called as anthracite or anthracite.It is the maximum coal of degree of coalification.Anthracite is solid
Determine carbon content height, volatile producibility is low, and density is big, and hardness is big, and burning point is high, and when burning does not smolder.Black is hard, there is metal light
Pool.Will not be stained with fat friction, fracture at conchoidal, when burning, flame is short and few cigarette.Noncoking.General phosphorus content 90% with
On, volatile matter is below 10%.Anthracite shows relatively high gasification reactivity, according to anthracitic Industrial Analysis as a result, nothing
Why bituminous coal shows high gasification reactivity, due principally to the coal there is high-moisture, low ash content, high-carbon content and height to wave
The characteristics of hair divides.
Alkali carbonate to the apparent catalytic action of coal gasification early in nineteen twenty-one by propositions such as Taylor, in view of soda
Be widely present and it is more cheap and easy to get, for a long time in relation to sodium carbonate catalytic gasification research carried out a large amount of reports.Especially
The salt of the carbonate of potassium, sodium, alkaline-earth metal and transition metal is all the good catalyst of catalytic gasification.The catalytic gasification of coal is one
The typical gas-solid heterogeneous reaction of kind, vapor-phase reactant will react on the coal surface for being loaded with catalyst with carbon, catalyst
Activity depends on the specific surface area of coal and its dispersion degree on coal surface.Sodium carbonate（Potassium）Alkali metal and carbon shape are removed on coal surface
Outside activated centre at oxide on surface group, can also change the pore structure on coal surface, and under gasification temperature into one
Step melting diffusion can make the activity of coal be improved.Exxonmobil companies of the U.S. are with K2CO3As catalyst, have developed with
The pressurised fluidized bed catalysis gasification technique of coal for the purpose of substitute natural gas is produced, K is added2CO3After catalyst, in same reaction
In, efficiency of carbon con version greatly improves, reaction rate also improve about 4 times (Energy Research, 1980,4:137-
147).Compared with single component catalyst, multicomponent catalyst has higher gasification efficiency, is paid high attention to recently by researcher.
Akyurtlu etc. is with K2SO4And FeSO4Mixture be catalyst gasification research, reaction condition are carried out to Pittsburgh's HVA coal tars
For：K/Fe molar ratios are 9, temperature is 850 DEG C, the atomic ratio of pressure 0.1MPa, metal/carbon is 0.02, content of metal is
5.1~7.3g/100g carbon, carbon particle size be 53 μm~106 μm, reaction gas H2O/H2Or H2O/N2（H2O content is
30%）, charcoal percent conversion can reach 100%, and under same reaction conditions, K is used alone2CO3As catalyst, charcoal percent conversion
Only 89%（Fuel Processing Technology, 1995,43:71-86）.Sheth etc. uses three-way catalyst respectively
Li2CO3-Na2CO3-K2CO3, binary catalyst Na2CO3-K2CO3, monolithic catalyst K2CO3Gasification kinetics research is carried out to coal,
It was found that the activation energy of catalytic gasification is less than the activation energy of binary catalyst and monolithic catalyst catalytic gasification, this is
Due in gasification temperature（700 DEG C~900 DEG C）Under, three-way catalyst is in a liquid state, and binary catalyst and monolithic catalyst K2CO3
For solid-state.Since catalyst exists with liquid, good fluidity, it is easier to be diffused into reaction system, the active sites of coal are corresponding
Increase, therefore activity is relatively high（Fuel, 2004, 83:557-572）.But sodium carbonate（Potassium）Coal surface excess or
Accumulation easilys lead to mutually cohering under molten state and slagging, to be had adverse effect on to catalytic gasification process.Therefore,
It is badly in need of a kind of not easy in inactivation of exploitation, methanation effect is good, is more easy to evenly dispersed base metal catalysts, realizes catalytic coal gasifaction skill
Art industrialization bottleneck is broken through.
