We report experimental setups and conditions leading to pyrolysis of such gaseous hydrocarbons as methane, mixed propane and butane, at the temperatures below $200^oC$, and liquid hydrocarbons of black oil at $300^oC$. The latter process gives out up to 48\% of light fractions capable for further processing to kerosene. Both types of pyrolysis are mechanically assisted by putting of the substances being decomposed into a dynamic interaction with the tin and bismuth alloy in its melted condition. Depending on actual conditions of this dynamic interaction, part the carbon particles rests in the alloy during its solidification thus creating highly developed fractal-like porous structure in the solid.
