摘要： Disclosed is a method for preparing vinyl chloride by catalytic thermal cracking of 1,2-dichloroethane, in which method the heat required for the thermal cracking is supplied via a liquid or condensing heat transfer medium, wherein, the heat transfer medium is heated at least in part by means of waste heat from a plant for combusting liquid and/or gaseous residues of a chemical plant. The invention also relates to a plant for preparing vinyl chloride by catalytic thermal cracking of 1,2-dichloroethane. The heat required for thermal cracking can be obtained from cheaply available waste heat. For example, it is possible to temporarily heat the heat transfer medium exclusively by means of the second heating device operated by waste heat, wherein said waste heat can, for example, be waste heat from a plant for preparing vinyl chloride.

摘要： Fuel converters configured to convert a transportation fuel to a low-C hydrocarbon fuel, along with methods of their use, are provided. The fuel converter can comprise: an evaporator configured to receive a transportation fuel from a fuel tank in a liquid state, wherein the evaporator converts the transportation fuel from a liquid to a gas; a fuel burner configured to heat the evaporator; a catalyst cartridge in fluid communication with the evaporator so as to receive the gas from the evaporator; and a condenser in fluid communication with the catalyst cartridge so as to receive the reaction product mixture from the catalyst cartridge. The catalyst cartridge comprises a catalyst configured to convert the transportation fuel into a reaction product mixture comprising a low-C hydrocarbon fuel. The condenser is configured to separate the low-C hydrocarbon fuel from a condensed fuel in the reaction product mixture.
