Abstract Climate change and increasing world population call for careful utilization of water energy sources. Microalgae to treat wastewater in a coupled process produce biofuels other value-added products human consumption are promising solutions. An analysis culture parameters cultivation processes is presented as essential achieve economical sustainability from the algae. Results activity mi...

In the last decades, ion current sensing has been widely recognized as a promising approach to engine knock/super knock detection. However, formating mechanism under knocking conditions is yet be revealed, which substantially hinder further development of based detecting technology. this paper, signals detected are investigated both experimentally and numerically. spark ignition engine, signal ...

A genetic algorithm is used to optimize the modified benzene alkylation process. Based on the previous studies, the modified process increases ethylbenzene selectivity and decreases energy consumption at the same time. The inlet ethylene flow rate of each alkylation reactor is optimized in order to reduce the chance of transalkylation reactions but increase ethylbenzene selectivity. The byprodu...
