Abstract:
A continuous process for producing a desired hydrocarbon product from a conversion chemical reaction which utilizes a solid catalyst in powdered form comprising:a) providing a reactor having a top portion and a bottom portion wherein the length to diameter ratio of the reactor is greater than about 2:1; b) loading a powdered heterogeneous catalyst into said reactor, where the mean particle size of the catalyst is less than about 90 microns; c) feeding to said bottom portion of said reactor at least one liquid reactant at a velocity sufficient to disperse said catalyst in said liquid reactant without the use of agitation or back mixing and in the absence of gas bubbles to form a bed reaction zone wherein said velocity is at least equal to the minimum fluidization velocity and less than the minimum entrainment velocity wherein catalyst exits said bed reaction zone in the liquid; d) subjecting said liquid reactant to catalyzing conditions in said bed reaction zone whereby said desired hydrocarbon product is formed at a conversion rate of higher than 97%; and e) removing said desired hydrocarbon product from said top portion of said reactor.
