Abstract: Data on the most important combustion and detonation parameters, such as wave velocities, pressures and temperatures of products, specific energy release of mixtures are presented for saturated $\mathrm{C}_n\mathrm{H}_{2n+2}$ (from methane $(n=1)$ to eicosane $(n=20)$) and unsaturated $\mathrm{C}_n\mathrm{H}_{2n}$ (from ethylene $(n=2)$ to eicosene $(n=20)$) hydrocarbons, methanol and ethanol as the main components of biofuels, and monofuels as a source of bifurcation structures of multifrontal detonation. Data are also given on on the critical initiation energies as a measure of the explosion hazard of combustible systems: the lower the energy, the more dangerous the mixture. Data were obtained for mixtures of each individual hydrocarbon with oxygen and air in a wide range of initial parameters: pressure, temperature, concentration and phase state of fuel components.

Keywords: initiation, critical energy, detonation cells, safety, ecology, alternative fuels, databases.
