摘要: A method for synthesizing a crystalline molecular sieve SSZ-13, characterized in that the method comprises bringing the following raw materials into contact in water under a crystallization condition: at least one tetravalent silicon source, at least one trivalent aluminium source, at least one alkali metal compound, choline cations and/or SSZ-13 seed crystals, and hydroxide ions. The method avoids using benzyl trimethyl quaternary ammonium ions (BzTMA+) or N,N,N-trimethyl-1-amantadine cations as structure-directing agents, and obtains high-quality crystal molecular sieve SSZ-13. Due to the use of a low-cost nontoxic structure-directing agent, the method has low production price by employing a low-cost nontoxic template, and can be popularized for application.

摘要: An integrated purification method and an integrated purification system for an industrial exhaust gas containing cyanides, hydrocarbons and NOx. The method comprises the steps of: 1) subjecting the exhaust gas containing pollutants such as cyanides, hydrocarbons and nitrogen oxides (NOx) to a gas-liquid separation device (1) to separate the free fluid, then mixing with the air blown by the air blower (201, 202), and preheating by the heating unit; 2) the mixture entering into the selective catalytic combustion (SCC) reactor (5) for the selective catalytic combustion reaction to convert harmful substances into CO2, H2O and N2, the catalysis being performed in two stages: the earlier stage is catalyzed by supported molecular sieve catalyst, and the latter stage is catalyzed by supported precious metal catalyst; and 3) the gas came out from the SCC reactor (5) entering into the heating unit to recover the heat, and then the purified exhaust gas being discharged directly through the chimney (6). The system comprises a gas-liquid separation device (1), a heating unit and a selective catalytic combustion reactor (5), a gas outlet of the gas-liquid separation device (1) being connected to the selective catalytic combustion reactor (5) through the heating unit, and an exhaust gas outlet of the selective catalytic combustion reactor (5) being connected to a chimney (6) through the heating unit.
