Abstract
A hydrocarbon is converted to a higher-molecular-weight hydrocarbon having greater unsaturation in compact and efficient apparatus, which provides for recirculating materials in a continuous process.
Claims20
A process for converting an alkane to a higher molecular weight alkene, which comprises:
- a) chlorinating the alkane to produce the corresponding alkane chloride and hydrochloric acid, and
- b) reacting the obtained alkane chloride and hydrochloric acid with a metal oxide to form a metal chloride, water vapor and an alkene of higher molecular weight than said alkane.
A process for converting an alkene to a higher molecular weight alkyne, which comprises:
- a) chlorinating the alkene to produce the corresponding alkenyl chloride and hydrochloric acid, and
- b) reacting the obtained alkenyl chloride and hydrochloric acid with a metal oxide to form a metal chloride, water vapor and an alkyne of higher molecular weight than said alkene.
Apparatus which comprises:
- a) reactor means for converting a hydrocarbon and chlorine to the corresponding hydrocarbyl chloride and hydrogen chloride,
- b) reactor means for converting the hydrocarbyl chloride, the hydrogen chloride, and a metal oxide to a metal chloride, water vapor and a hydrocarbon of higher molecular weight and of a higher degree of unsaturation,
- c) reactor means for converting the produced metal chloride and oxygen or air to the corresponding metal oxide and chlorine,
- d) means to recirculate the produced chlorine to reactor means (a),
- e) means to recirculate produced metal oxide to reactor means (b), and
- f) means to withdraw the higher molecular weight hydrocarbon and water vapor from reactor means (b).
