Loop-route production method and system for polyvinyl chloride
The present invention relates to a loop-route production method and system for polyvinyl chloride, and belongs to the intersecting fields of coal chemicals, polymer materials and chemical machinery. Limestone and carbon materials such as coal are reacted in an oxygen-enriched high temperature furnace to obtain calcium carbide and carbon monoxide, and then acetylene and carbon monoxide are respectively produced from calcium carbide and dichloroethane (obtaining ethylene, etc., through methanol or ethanol); both of the end products are combined to form a closed-loop; acetylene and dichloroethane are reacted to produce a vinyl chloride monomer, which is polymerized to obtain polyvinyl chloride. The system of the present invention mainly includes a device for pulverizing and mixing solid raw materials, a device for conveying solid materials, an oxygen-enriched calcium carbide furnace, an oxygen-enriched air-blowing device, a tube-shell thermostatic reactor, a fixed bed tubular reactor, a fluidized bed reactor, an acetylene generator having a heat exchanger, a fixed bed reactor and a polymerization reactor. The present invention has the advantages of not only removing the dependence on oil resources during the production of polyvinyl chlorides, but also totally eliminating the mercury pollution.
Production of acrylic acid and ethanol from carbonaceous materials
A process for producing acrylic acid from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce acrylic acid.
Method of transforming biomass into hydrocarbon
A method is provided to transform biomass. Non-food biomass is preprocessed. Then, fermentation is processed to generate ethanol. Ethanol is dehydrated through a catalyst to generate ethylene. After the dehydration, oligomerization is processed with a catalyst to transform ethylene into olefins having 6˜20 carbon atoms (C.sub.6˜C.sub.20). The olefins are hydrotreated into alkanes. Thus, C.sub.6˜C.sub.20 hydrocarbons having long carbon chains are formed. The hydrocarbons having 6˜10 carbon atoms can be used as gasoline; those having 8˜16 carbon atoms, jet fuel; and those having 16˜20 carbon atoms, diesel. On generating ethanol, byproducts of lignin may be generated. The byproducts can be processed through depolymerization/deoxygenation to generate aromatic hydrocarbons or can be gasified to generate methanol or dimethyl ether. By further processing dehydration, aromatic hydrocarbons are generated to be mixed into gasoline, jet fuel or diesel. Or, the lignin byproducts are gasified to generate syngas.
