Advances in technology for preparing biodiesel from waste oil with high acid value;

Study on a new catalyst of solid acid for preparation of bio-diesel from waste oil;

Enzymatic synthesis of biodiesel from waste oil;

Optimization of technological conditions in synthesis biodiesel from waste oil with supercritical methanol;

Taking waste oil as raw material of biodiesel was in accordance with the situation of our country.

Preparation of cationic starch modified flocculant and its performance on oil-containing wastewater;

The capability of treating oil and grease wastewater was enhanced greatly by bioaugmentation with dosing X4 in active sludge system.

A study of Member bioreactor with CASS and PVDF ultra-filtration membrane, integrating A/O process for treatment of oil and grease wastewater from a refectory was carried out.

Methods: In the course of aerobic bio-fluidized-bed treating oil and grease wastewater, the treatment is bioaugmented by the addition of high effective oil-grease degradation culture.

Application of high efficient strain in the treatment of oil wastewater;

Engineering example of oil wastewater treatment by physicochemical and biochemical technology;

Flocculation pretreatment of strong acid oil wastewater with high concentration of SO2-4 was investigated.

With waste edible oil as raw material to produce biodiesel,free fatty acid has to be removed before used,it will be impractical because the process is complex and the cost is high.
