Combined Heat and Power (CHP) is the simultaneous productions of electricity and heat from the combustion of a single fuel. CHP may be renewable if renewable fuels (biomass, biofuels,.) are used. In general, it is not renewable. A typical CHP configuration shows a natural gas fired Internal Combustion Engine (ICE).

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).
