    • A system and a method for assessing risk in integrated environment management, and a computer-readable recording medium storing a program thereof are provided to effectively reduce society waste caused from polemic argument by efficiently and properly assigning human/physical resources based on predetermined priority and offering basis capable of outputting a reasonable agreement between a policy planer and local residents. A multimedia environment behavior model assesses multimedia environment behavior of harmful chemicals for a target area by using a physical/behavior property database of the chemicals, an environment/geographic property database, a meteorological database and a discharge scenario database. A risk evaluation model is formed based on a toxic database and a human exposure variable database, and calculates the risk of the chemicals by each medium and exposure path. An ecological risk evaluation model is formed based on an ecological toxic database, a physical/chemical property database, and a usage/property/behavior property database of the chemicals. A user terminal executes the databases and the models.

    • PURPOSE: Disclosed is a honeycomb monolith catalyst for the elimination of VOCs, which is characterized in that a hydrophobic zeolite being supported with palladium ion (Pd¬2+) and transition metals is mixed with a binder, and then washcoated on a cordierite honeycomb monolith. This honeycomb monolith catalyst shows an excellent catalytic activation at a temperature range of 260deg.C or lower, especially even in the presence of excess moisture. CONSTITUTION: This honeycomb monolith catalyst is prepared by supporting metal salts comprising palladium ion and transition metals such as Cu, Mn, Ni, Cr, and Co on a hydrophobic zeolite selected from USY-zeolite(SiO2/Al2O3=10 - 1000), ZSM-5 zeolite (SiO2/Al2O3=20 - 1000); adding a binder selected from bentonite, silica colloid, and methylcellulose for obtaining slurry-phase catalyst; washcoating prepared slurry-phase catalyst on a cordierite honeycomb monolith. In this method, palladium ion of 0.1 to 2.0wt.% and transition metal of 5 to 30wt.% (based on the weight of hydrophobic zeolite) are supported on the hydrophobic zeolite respectively, and it is characterized in that the amount of palladium and the amount of transition metal applied on the cordierite honeycomb monolith are respectively 0.03 to 0.8g/L-honeycomb and 2.0 to 15.0g/L-honeycomb.
    • 本发明公开了一种用于消除VOC的蜂窝状整体式催化剂,其特征在于用钯离子(Pd 2 +)和过渡金属负载的疏水性沸石与粘合剂混合,然后用堇青石蜂窝单块 。 该蜂窝状整体式催化剂在260℃或更低的温度范围内显示出优异的催化活性,特别是即使在过量水分存在下。 构成:该蜂窝状整体式催化剂是通过在选自USY-沸石(SiO 2 / Al 2 O 3 = 10-1000),ZSM-5的疏水性沸石上负载包含钯离子和过渡金属如Cu,Mn,Ni,Cr和Co的金属盐而制备的。 -5沸石(SiO 2 / Al 2 O 3 = 20-1000); 加入选自膨润土,二氧化硅胶体和甲基纤维素的粘合剂以获得淤浆相催化剂; 在堇青石蜂窝整料上涂覆制备的淤浆相催化剂。 在该方法中,分别在疏水性沸石上负载0.1至2.0重量%的钯离子和5至30重量%的过渡金属(基于疏水性沸石的重量),并且其特征在于钯和 施加在堇青石蜂窝单块上的过渡金属的量分别为0.03〜0.8g / L蜂窝和2.0〜15.0g / L蜂窝。
