Direct production of biodiesel from renewable oils using calcined blast furnace dust

Recently, Dr Ms. Yi-Tong Wang (Associate Professor, College of Metallurgy and Energy, North China University of Science and Technology) and Prof. Zhen Fang published an article in Renewable Energy using calcined blast furnace dust as catalyst material for biodiesel production.

Direct production of biodiesel by both esterification and transesterification of renewable oils with acid value (AV) of 9.6-28.9 mg KOH/g using calcined blast furnace dust is studied. Blast furnace dust calcined at 600-700 ^oC obviously promotes efficient biodiesel production because of the crystal form transformation from lead sulfate particles in dust into active lead oxide, lead sulfide, and lead particles. It is found for the first time that lead oxide, lead sulfide and lead particles can resist saponification from fatty acids to catalyze raw renewable oils to biodiesel with catalytic activity order as follows: lead oxide > lead > lead sulfide > lead sulfate. Biodiesel production process is optimized according to an orthogonal design with biodiesel yield of 92 wt% obtained at AV of 9.6 mg KOH/g (82 wt% after 5 cycles). Biodiesel yield of 84 wt% is achieved at AV of 28.9 mg KOH/g with acidity of 0.18 mmol/g. Calcined blast furnace dust presents potential applications in the production of biodiesel from renewable oils with high AVs.

MOF-based functional catalytic materials for biodiesel production

Recently, PhD student Miss Wen-jie Cong supervised by Prof. Zhen Fang, collaborated with Profs. Hu Li at Guizhou Univ, JA Kozinski at Lakehead Univ and AK Dalai at U of Saskatchewan in Canada, published a review article in Green Chemistry about metal-organic framework-based functional catalytic materials for biodiesel production.

At present, the key point of the biodiesel industry is to find cheap and widely sourced feedstock to reduce production costs. High-efficiency heterogeneous catalyst can enhance biodiesel yield from low-quality feedstocks. Metal-organic frameworks (MOFs) have attracted extensive attention in the field of clean energy and chemicals due to their porous, controllable structure and good compatibility. However, the application of MOF materials on biodiesel production is still in its infancy but their usage is on the rise year by year. There is no relevant review article to summarize and point out the work and defects in this field. This review focuses on MOF-based functional catalytic materials for biodiesel production. Catalytic performance of MOF-based catalysts, synthesis method and catalytic loading strategy are described in detail. This review also analyzes the mechanism of functionalized MOFs classified via enzyme, base, acid, and bifunctional catalysts and summarizes technologies employing MOF-based catalysts for biodiesel production. Additionally, technical perspectives on the feasible reaction mechanisms are discussed, and the realistic necessity of MOF-based nanocatalysts is provided. The MOF-based functional catalytic materials show great potential in biodiesel production and other relevant biorefineries.

Diamond Anvil Cell System

Prof. Zhen Fang studied quantitative (visual and microscopic) assessment of the behavior of biomass and plastics in supercritical water (SCW) and designed unique diamond anvil cell (DAC) system in Canada (McGill), leading to the invention of “fast hydrolysis process”.

Prof. Zhen Fang further studied one-pot and low-temperature synthesis of liquid biofuels and chemicals from carbohydrates (Nat Commun; 2 PCT, 2 patents). This unique process almost completely converts lignocelluloses, after hydrolysis and decomposition, to imides and liquid fuels (2,5-dimethylfuran, methyl levulinate, gamma valerolactone, methylfuran).

Prof. Zhen Fang was appointed as Member of the Academic Degree Committee of the State Council of China (2020-2025).
