In this work, we will report a new liquid/inorganic membrane product concept for CO2 separation. A liquid fluid of selective CO2 absorption properties is immobilized in a thin, inorganic substrate sheet (20~50um) of graded pore structures. CO2 selectively absorbs into the liquid fluid in the feed...

There is no doubt that crude oil will be depleted eventually. The concept of global warming is now well accepted. Given these twin constraints, it behooves us to find alternative fuels, especially liquid ones for transportation. Microalgae have the potential to both reduce increases in greenhouse...

To control the size and shape of crystals during batch crystallization, one must either have an accurate crystal growth and nucleation model or run a series of experiments to find the optimal operating conditions. Since the former is a very intricate and time-consuming task, especially for new...

A solar thermal reactor receives concentrated solar irradiation and uses this energy to thermally convert biomass into synthesis gas (H2, CO and CO2). The operation of this reactor is affected by the presence of clouds, which act as a disturbance for this process. When clouds are partially covering...

The sorption, diffusion and swelling properties of methanol vapor in a short-side-chain perfluorosulfonic acid ionomer (PFSI) membrane of equivalent weight 860 gpol/(mol(SO3H) were investigated at different activities and at temperatures between 35 and 65°C. The solubility isotherms can be well...

As concerns over U.S. energy security and global warming increase, the need to develop alternative and renewable sources of energy is more important than ever before. One promising renewable energy scenario involves the use of microalgae as feedstocks that convert solar radiation and CO2 into...
