Catalyst for inducing thermal desorption of organic matter-contaminated soil and preparation method thereof
A catalyst for inducing thermal desorption of organic matter-contaminated soil and a preparation method thereof, which uses a colloidal mixture of ferroferric oxide and ferric chloride as a catalytic active component of thermal desorption, and carbon tetrachloride as a solvent. Based on the mass of solvent, a mass percentage of catalytic active component is 0.1%-15%. Ammonia water is added dropwise to ferric chloride aqueous solution to react in oil bath to generate a ferroferric oxide colloidal solution, then ferric chloride and obtained ferroferric oxide colloidal solution are added to carbon tetrachloride, and mixed solution is continuously stirred in an oil bath to evaporate solvent water to prepare a catalyst with carbon tetrachloride as solvent. Catalyst is environmentally friendly and can induce thermal desorption of organic matters in soil. 100% desorption of chlorobenzene, o-xylene and benzo[A]anthracene can be achieved at 130? C., and energy consumption of thermal desorption is greatly reduced.
CATALYST COMPOSITIONS FOR SELECTIVE DIMERIZATION AND POLYMERIZATION OF ETHYLENE
A catalyst composition comprises an inert hydrocarbon solvent, having dissolved therein a titanate of the formula Ti(OR).sub.4 wherein each R is the same or different, and is a hydrocarbon residue, and an organic aluminum compound, wherein a molar ratio of the organic aluminum compound and any alkene present in the catalyst composition is greater than one.
ALKYLATION PROCESSES USING LIQUID LEWIS ACID CATALYSTS
An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.
