With ferrous sulfate by-product from the production of titanium dioxide as main raw material, iron oxide yellow was prepared. Not only the effects of mass ratio of NaO H to FeSO 4 ×7H 2 O, initial Fe 2+ concentration, aeration rate and temperature on the seed crystal, but also those of concentration of seed crystal, p H value and initial ferrous sulfate amount on the iron oxide yellow examined. The process conditions were optimized. The results showed that the production was 4.00 g, the productivity was 12.01 g/h, the seed crystal was claybank and colloid when the molar ratio of Na OH to FeSO 4 ×7H 2 O was 0.5, initial Fe2+ concentration 0.7 mol/L, aeration rate 2.5 L/min and temperature 35 ℃ in the preparation stage of seed crystal. Meanwhile, the production was 20.97 g, the productivity was 8.99 g/h, the iron content in oxide was 86.95% when the concentration of seed crystal was 20%, p H value 4.5 5.0, initial ferrous sulfate amount 60 g in the preparation stage of iron oxide yellow. The prepared iron oxide yellow was homogeneous claviform particles with the phase composition of Fe OOH, average diameter 860 nm, and specific surface area 21.98 m2/g, and its quality was over the first grade of industrial standard HG/T 2249-91.

Copper in the chlorination dust of copper-containing slag was recovered through the hydrochloric acid agitation leaching-N902 extraction process, and the main influential factors on the leaching of the chlorination dust were studied. The results show that under the conditions of 15% concentration of hydrochloric acid, ratio of liquid to solid 4 m L/g, reaction temperature 60 ℃ and reaction time 1 h, the leaching rate of copper is 98.95%. Meanwhile, the leaching rates of iron, nickel and zinc are 91.58%, 95.8% and 93.66%, but the leaching rate of lead is low at 5.96%. The leaching process realizes the separation of copper and lead effectively. N902 for copper extraction has good selectivity. When the mixing time, phase ratio, N902 concentration and p H value are 120 s, 1:1, 30% and 3.0 respectively, the copper concentration in the leaching solution decreases from 7.4 to 0.11 g/L, the extraction rate of copper is 98.51%, and the extraction rates of iron, nickel, zinc and lead are all lower than 1.5%.
采用盐酸搅拌浸出—n902萃取工艺回收含铜渣氯化粉尘中的铜，并对氯化粉尘浸出的主要影响因素进行了研究。结果表明，在盐酸浓度为15%、液固比为4 m L/g、反应温度为60℃、反应时间为1 h的条件下，铜的浸出率可达98.95%。铁、镍、锌的浸出率分别为91.58%、95.8%和93.66%，而铅的浸出率较低，为5.96%。浸出工艺有效地实现了铜铅的分离。N902对铜的萃取有很好的选择性。当混合时间为120 s、相比为1:1、N902浓度为30%、p H值为3.0时，浸出液中铜的浓度从7.4 g/L降至0.11 g/L，铜的提取率为98.51%，铁、镍、锌、铅的提取率均低于1.5%。

Models for hydrolysis, fermentation and concentration process, production and utilization of biogas as well as lignin gasification are developed to calculate the heat demand of ethanol production process and the amounts of heat and power generated from residues and wastewater of the process. For the energy analysis, all relevant information about the process streams, physical properties, and mass and energy balances are considered. Energy integration is investigated for establishing a network of facilities for heat and power generation from wastewater and residues treatment aiming at the increase of energy efficiency. Feeding the lignin to an IGCC process, the electric efficiency is increased by 4.4% compared with combustion, which leads to an overall energy efficiency of 53.8%. A detailed sensitivity analysis on energy efficiency is also carried out.
