The present invention relates to an integrated process that allows the production of tert-butyl ethers of glycerol, used as a high boiling point solvent (HBPS) in paint formulations (water-based) and cleaning products, or a stream of isooctenes to be used as an octane in the gasoline pool, in a simple way, just directing the flow through the areas necessary for the conversion and separation of the process and using the same equipment, aiming at gains in process yield (maximization of glycerol and isobutene conversions) and minimizing investment and operating costs. In view of this, there is a unit flexibility in producing different high added value products.

Provided is a method of producing an oligomer, the method including: supplying a monomer stream and a solvent stream to a reactor to perform an oligomerization reaction to produce a reaction product; supplying a discharge stream of the reactor to a separation device, and supplying an upper discharge stream of the separation device including an unreacted monomer to the reactor and supplying a lower discharge stream of the separation device to a settling tank; settling a polymer in the settling tank and removing the polymer, and supplying the lower discharge stream of the separation device from which the polymer is removed to a high-boiling point separation column; removing a high-boiling point material from a lower discharge stream of the high-boiling point separation column and supplying an upper discharge stream of the high-boiling point separation column including an oligomer to a solvent separation column; and separating a solvent and the oligomer in the solvent separation column.

The present disclosure provides an apparatus for preparing oligomer including: a reactor; a gas-liquid separator; a solvent transfer line; a second transfer line; a first spray nozzle unit; and a second spray nozzle unit. The apparatus is capable of improving stability of the entire process by including a first spray nozzle unit and a second spray nozzle unit in a reactor and thus preventing by-products containing polymer substances such as C20+ from being entrained with a desired product during a reaction.

A phosphorous modified zeolite (A) can be made by a process that includes selecting a zeolite, steaming the zeolite, leaching the zeolite, separating solids from liquid, and calcining. An olefin product can be made from an oxygen-containing, halogenide-containing or sulphur-containing organic feedstock by contacting the feedstock with the phosphorous modified zeolite (A) in an XTO reactor under conditions effective to convert at least a portion of the feedstock to olefin products. The XTO reactor effluent can include light olefins and a heavy hydrocarbon fraction. The light olefins can be separated from the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can be contacted in an OCP reactor at conditions effective to convert at least a portion of the heavy hydrocarbon fraction to light olefins.
