Bergius Process Synthetic Petrol: In this process, the finely powdered coal is completed keen on a paste through heavy oil and a catalyst powder (tin or nickel oleate) is mixed with it. The paste is pumped along with hydrogen gas into the converter, where the synthetic paste is heated to 400 450°C under a pressure of 200 250 atm.

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w). With the ...

Next to the wood gas technology, Fischer and Tropsch invented a synthesis process of diesellike fuel, which was patented in 1925. Conventional vehicle fuel could be substituted, which ultimately covered 90 % of German consumption at that time 40. Another way to produce fuel from brown coal (lignite) is the Bergius Pier process.
