摘要:
The invention relates to a process for producing hydrocarbon components, comprising: providing a feedstock comprising tall oil and terpene-based compounds; subjecting the feedstock and a hydrogen gas feed to a hydroprocessing treatment in the presence of a hydroprocessing catalyst to produce hydrocarbon components including n-paraffins, and subjecting the hydrocarbon components including n-paraffins to isomerisation in the presence of a dewaxing catalyst to form a mixture of hydrocarbon components. The invention also relates to an apparatus for implementing the process. The invention further relates to a use of the hydrocarbon components produced by the process as a fuel or as an additive in fuel compositions. The invention also relates to a use of a NiW catalyst on a support selected from AI 2 O 3 , zeolite, zeolite-AI 2 O 3 , and AI 2 O 3 -SiO 2 for producing fuel or an additive for fuel compositions from a feedstock comprising tall oil and terpene-based compounds.

A method to minimize catalyst deactivation rate and coke laydown, and maximize desired reaction rate in processing of industrially significant reactions under supercritical conditions to generate a reaction mixture stream including formed reaction products and reactants, said contacting at a desired catalyst temperature of about 1-1.2 critical temperature of the resulting reaction mixture and at a pressure between the critical pressure of the reaction mixture and a pressure necessary to establish said reaction mixture fluid density of greater than 0.65 gm/cc.
摘要:
A process and catalyst for isomerizing olefins are disclosed. The process and catalyst are particularly useful for isomerizing alkenyl bridged ring compounds to the corresponding alkyladiene bridged ring compounds. The isomerization catalyst comprises an oxygen treated mixture of an alkali metal on a calcined support having a surface area of 125 to 195 m2/g. The catalyst is particularly useful for isomerizing 5-vinyl-2-norbornene to 5-ethylidiene-2-norbornene. The catalyst is very active and highly selective and resistant to catalyst poisons. The process contacts the catalyst with an alkenyl bridged ring compound and yields the corresponding alkyladiene bridged ring compound.
