He precept of the motion of antiknocks includes fighting explosive decomposition of the goods of pre-ignition oxidation of the gasoline earlier than general combustion of the gasoline mixture starts off. There are numerous theories that specify the essence of knock combustion. the main broadly accredited one is the so-called peroxide idea.

Polymerizations Terpolymerizations of styrene and methacrylate monomer mixtures were performed isothermally at 100 °C in SN-150 mineral base oil solution, under nitrogen atmosphere. Reactions were carried out in an oil jacketed glass reactor of 1 dm 3 volume, equipped with a stirrer and reflux condenser. The total monomer concentration was 50 wt. %. 0 wt. % relative to the monomers. The complete conversion of monomers in the overall reaction cycle time of five hours was achieved by introduction of multiple initiator chaser shots during the course of a batch reaction.

These catalysts allow parallelly and serially conducting several processes on contact with the feedstock: hydrogenation, hydroisomerization, hydrocracking, hydrotreating to remove sulfur, etc. For this reason, the proposed technology can be described as energy- and resource-conserving. Hydrorefining was conducted on an enlarged laboratory entrained-flow unit at high pressure of 2 MPa, optimum temperature of 380°C, H 2:feedstock ratio of 200, and variation of the feedstock space velocity from 3 to 7 h -1.
