“…The CO conversion is lower in CSTR, the possible reasons could be the degree of reduction of the catalyst in CSTR and complete different flow pattern in CSTR. This similar observation was also reported from previous literature [12,42]. Therefore, in order to achieve a relative higher activity in CSTR, a higher reduction temperature over 3008C might be needed [43].…”

The Fischer-Tropsch synthesis (FTS) was studied using mesoporous silica-supported bimetallic Co-Ni catalyst in a fixed-bed reactor (FBR) and a slurry continuously stirred tank reactor (CSTR) under different temperatures (from 2808C to 3008C) with syngas ratio of 2 and a total pressure of 3.5 MPa. The activity of the catalyst was higher in FBR due to complete reduction. The CSTR was found to experience a less degree of catalyst deactivation, and its CO conversion was more sensitive in responding to the variation of temperatures because of its better temperature control. The intraparticle diffusion limitation was much improved in the CSTR system due to employment of smaller particle size of the catalyst. The selectivity of gasoline fraction (C 5 -C 13 ) was higher in CSTR system than that in FBR at the same baseline condition. The appreciable increases of selectivity in CO 2 , methane, and longer-chain hydrocarbon were observed in FBR when the comparable CO conversion was set for comparison between FBR and CSTR. Reducing the particle size of the catalyst was more effective in increasing the selectivity of lighter (C 2 -C 6 ) 1-olefin in CSTR system. The FBR produced higher selectivity of longer chain (C 7 1) 1-olefin.

“…The test tube was then placed in an oil bath and heated up to the temperature desired (190)(191)(192)(193)(194)(195)(196)(197)(198)(199)(200) • C). After the reaction, the crude was cooled, diluted with HPLC acetone, filtered and analyzed.…”

“…Hence, the authors suggested hydroxy sodalite zeolite membranes with a layer thickness of 2 µm as auspicious candidate for the in situ water removal due to their extraordinary separation and permeation performance demonstrated as well earlier by Khajavi et al [198]. Recently, a novel reactor configuration denoted as fixed-bed membrane reactor followed by fluidized-bed membrane reactor (FMFMDR) has been proposed for high temperature Fischer-Tropsch synthesis, in particular gasoline production from syngas [199,200]. This configuration combines a fixed-bed water permselective membrane reactor equipped with H-SOD zeolite membrane coated on α-Al 2 O 3 substrate and a fluidized-bed hydrogen permselective membrane reactor equipped with Pd-Ag membrane.…”

Literature on zeolite membranes in catalytic reactions is reviewed and categorized according to membrane location. From this perspective, the classification is as follows: (i) membranes spatially decoupled from the reaction zone; (ii) packed bed membrane reactors; (iii) catalytic membrane reactors and (iv) zeolite capsuled catalyst particles. Each of the resulting four chapters is subdivided by the kind of reactions performed. Over the whole sum of references, the advantage of zeolite membranes in catalytic reactions in terms of conversion, selectivity or yield is evident. Furthermore, zeolite membrane preparation, separation principles as well as basic considerations on membrane reactors are discussed.
