ln the first part of the thesis, the capability of activated carbon fiber (ACF) treated bydifferent kinds of acids for adsorption removal of thiophenic sulfur compounds was evaluatedin the batch-type adsorption process. The results show that the as-received ACF adsorbent,efficiently adsorbs the bigger size sulfur compounds, and the removal efficiency for the sulfurcompounds follows in the order of 4,6-DMDBT > DBT > BT > T. Effect of treatmenttemperature and time by SN acid (ratio of volume of H,SO4 to HNO, is 3:1) on ACFadsorption removal of thiophenic sulfur compounds was studied.The results show thatoxidation with SN acid at room temperature can remove the ashes or inorganic components ofthe ACF adsorbent as well as change in the surface chemistry，introduce theoxygen-containing functional groups such as carboxyl and hydroxyl, improve the adsorptioncapability of ACF for removal of thiophenic sulfur compounds.
Science and the project feasibility study report based on the in-depth market supply and demand analysis, the future price forecasting, the resources supply, construction scale, process route, equipment selection, environmental impact, energy conservation and emissions reduction, investment estimation and fund-raising, profitability and other aspects of scientific research, from the Angle of market, technology and economy, engineering project study and comparative analysis, and after the completion of the project have made the financial, economic and social environment for scientific forecast, for the project decision-making provides a fair and reliable, scientific investment advice.
“Activated carbon production and construction project” belongs to zhoukou xyz co., ltd. plans in zhoukou economic development zone (new) projects, proposed the project the total area of 25072.53 square meters about 37.59 acres), is expected to total investment of 95.0984 million yuan, including: investment in fixed assets of 83.8144 million yuan, flow capital of 11.284 million yuan, is expected to comprehensive income for 94.17 million yuan.The economic situation this year is generally characterized by a steady but positive trend, and more positive changes have taken place in economic development.
Under certain operating conditions, the gas mixture by adsorption bed, adsorption by adsorption, adsorption after a period of time, when starting from the adsorbent in the laminar flow of the gas adsorbed mass (or its concentration reaches a specified value), think bed fire, adsorption properties of adsorbent adsorption quantity at this time is called dynamic activity of adsorbent.The activity is not only related to the characteristics of adsorbents and adsorbents, but also related to temperature, concentration and operating conditions.The kinetic activity value of adsorbent is the main basis for the design of adsorption system.The adsorption rateThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, the adsorption process can be divided intoThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, which can be divided into the following steps
