Introduction

The possibility of using of a pair of compression piston - cylinder with the unique performance features for the conversion of hydrocarbons are discusses. The experimental facility enables working in the pressure range that would be unattainable in diesel engines. The necessary degree of compression is managed and maintained by the computer system with a feedback.

Purpose

We have developed an original compression reactor to produce synthesis gas and for the controlled oxidation of associated gas to ethers and peroxy compounds.

Method

The reactor consists of piston and cylinder that are cooled. They are driven by a crank mechanism with tension rod. The construction provides the controlled regulation mechanisms of the cylinder upper dead point Without lubrication as the surface to surface friction coefficient is low, there is no influence of lubricating materials during the process of chemical reactions inside of the reactor. The reactor construction enables to have a pressure above 100 atm in the chamber.

Results

We have carried out a series of primary research of the process of the controlled chemical reaction in the chamber up to the stage of the gas mixture oxidation and generation of ether and peroxide compounds. Pentane was used as a raw material. Main interest is the start up of a chemical reaction in methane and methane mixture to higher hydrocarbons. The calculated curve of methane and methane mixture oxidation indicates the necessity to maintain the reacting mixture pressure at the level of 90 atm. According to evaluations the pressure increase transfers the reacting system from the mode of chain ignition to the quasistationary mode of branched-chain oxidation, providing a high reaction rate at relatively low temperatures. It also minimizes the influence of heterogeneous processes resulting in the formation of deep oxidation products. Plasma initiation of the working mixture will lead to intensification of processes of conversion and increase the yield of peroxide compounds.
