Taking the paste of used lead acid batteries as studying object, reaction mechanisms and experiments were investigated between citric acid and PbO, PbO2and PbSO4. The results showed that: three reactions Gibbs function, between the citric acid and the PbO, PbO2and PbSO4, were less than zero, and the reaction could be spontaneous; XRD results showed that: the above three reactions could produce lead citrate, and after roasting of the three kinds of lead citrate precursor, the powders, Pb/PbO as their main ingredients, could be obtained at low reaction temperature.

Catalyst Efficiency

Fast pyrolysis is an attractive thermal conversion process to generate the alternative liquid fuel. However, the bio-oil obtained from biomass pyrolysis has polarity, instability and low energy density due to contained oxygenated compound. Hydrodeoxygenation (HDO) process is the most promising route for bio-oil upgrading through oxygen elimination. The products are suitable for co-feeding into the existing refineries. Metal catalyst and operating conditions play an important role in HDO efficiency. A summary of HDO process has been conducted with various metal catalysts, type of reactors, and reaction mechanisms. It also raises some challenges in improving catalyst efficiency, reducing hydrogen consumption, and effort to understand the HDO kinetics.
