In 1869 Berthelot had already reported to have produced oil from coal, but only around 1910, in Germany (for cogent reasons), the subject was taken up in earnest. First Bergius, and then Pier (of the BASF, not fortuitously either) developed what was

To increase the content of well-dispersed aluminum in Al/SBA-15 and its Bronsted acidity, a water-free synthesis method involving a Si–O–Al precursor was employed to prepare a series of Al/SBA-15 of widely varying composition. The materials were

By following the selective H/D exchange of acidic hydroxyl groups in aluminosilicates by IR spectroscopy, clear evidence is provided for the existence in amorphous silica−aluminas (ASAs) of Bronsted acid sites comparable in strength to the bridging
