Recently, Dr Yi-Tong Wang (Associate Professor, female, College of Metallurgy and Energy, North China University of Science and Technology) and Prof. Zhen Fang published an article in Catalysis Today about highly stable heterogeneous catalysts from electric furnace dust for biodiesel production.
Highly stable heterogeneous catalysts were prepared by impregnating carbonates suspension solutions onto electric furnace dust (EFD) and being calcined at high-temperature for the production of biodiesel from soybean oil. Process of impregnating with CaCO3, BaCO3, SrCO3 and CdCO3 suspension solutions and being calcined at high-temperature did not promote improvement of catalytic activity of EFD powder, while the single impregnating with K2CO3 suspension solution can only improve its catalytic activity in the first use. Na2CO3@EFD catalyst synthesized by impregnating with only Na2CO3 suspension solution owned considerable catalytic activity from nano Na2CO3 (37.0 nm) and good recyclability from nano Fe3O4 (size of 30.0 nm & Ms of 26.77 Am2/kg) with biodiesel yield of 99.13 wt% at 65 oC in 2 h with 15/1 methanol/oil molar ratio and 7 wt% catalyst dosage in the first use (93.50 wt% in the eleventh use). The kinetic study with Na2CO3@EFD was carried out, and it was found that the activation energy was 32.81 kJ/mol and the frequency factor was 3760.85 /min, lower than reported solid base catalysts, which suggested synthesized Na2CO3@EFD catalyst owned remarkable potential for industrial application in biomass energy conversion.

Highly stable heterogeneous catalysts were prepared with carbonates suspension solutions impregnating onto electric furnace dust to catalyze the production of biodiesel from soybean oil with biodiesel yield of 99.13 wt% in the first use (93.50 wt% in the eleventh use). 电炉粉尘通过碳酸盐悬浊液浸渍后制备长寿非均相催化剂用于催化制备生物柴油，产率高达99.13 wt%，循环使用11次后产率仍可达到93.50 wt%。

电炉粉尘制备长寿非均相催化剂用于生物柴油的生产及反应动力学研究
最近，王一同博士（女，华北理工大学冶金与能源学院副教授）和方真教授在国际学术期刊Catalysis Today（IF: 6.766, Q2）发表题为“电炉粉尘制备长寿非均相催化剂用于生物柴油的生产及反应动力学研究”的研究性论文。
利用碳酸盐悬浊液湿法浸渍电炉粉尘和高温煅烧的手段制备长寿非均相催化剂用于催化豆油制备生物柴油。用CaCO3、BaCO3、SrCO3、CdCO3悬浊液和K2CO3溶液浸渍和高温煅烧对电炉粉尘的催化活性没有显著影响。用Na2CO3溶液浸渍合成的Na2CO3@EFD催化剂具有较好的催化活性和可循环性，生物柴油的产率为99.13 wt%，循环是11次后仍可获得93.50 wt%的产率，催化剂回收率> 90 wt%。对Na2CO3@EFD催化剂进行动力学研究，发现活化能为32.81 kJ/mol，频率因子为3760.85 /min，低于已经报道的固体碱催化剂，表明合成的Na2CO3@EFD催化剂具有显着的潜力用于生物质能转化的工业应用。详情可见：
