Hydrogen separation from the refinery off-gas of the ethylene decomposition was carried out with Pd-1wt.%Au alloy membranes deposited on a porous nickel support using the sputtering and polishing method. In order to verify the effect of ethylene on the membrane, hydrogen permeation tests were...

This study investigates configuration of a module for withstanding high pressure and temperature for CO2 capture from a coal gasifier. In order to increase the durability of the module at high pressure and temperature, a flange-type unit-cell module was installed in a high-pressure chamber....

CO in the hydrogen stream must be reduced to extremely low levels, under 10 ppm, because the Pt electrode is detrimentally affected by residual CO in the H2 stream. Therefore removal of carbon monoxide from the H2-rich stream during fuel generation from hydrocarbons is a critical challenge,...

The BTL (biomass-to-liquid) process is an attractive process that produces liquid biofuels from biomass. The FT (Fisher–Tropsch) process is used to produce synfuels such as diesel and gasoline from gasified biomass. However, the H2S (hydrogen sulfide), COS (carbonyl sulfide) and CO2 (carbon...

To enhance clean energy utilization and reduce greenhouse gases, various gasification technologies have been developed in the world. The gasification characteristics, such as syngas flow rate, compositions, cold gas efficiency and carbon conversion, of petroleum coke and mixture of petroleum...

We explore the impact of partisanship in state governments on policy expenditures and priorities in a public policy area where the distribution of policy preferences does not fall clearly on the standard left-right political spectrum. We begin with the assumptions that (1) partisanship affects...
