POMS 22 nd Annual Conference Reno, Nevada, U.S.A. April 29 to May 2, 2011 Abstract: MTS-MTO system is suitable where standard modules are shared by various finished products through divergent finalization. The system can satisfy product variety by taking advantage of flexibility of MTO, but its performance is lowered when the capacity is constrained. One way of dealing with the problem without ...

The methanol to hydrocarbon process, discovered about 40 years ago, uses zeolites to catalyze the shape selective conversion of methanol to a mixture of hydrocarbons. It has recently gained very much interest, as it allows the conversion of fossil and renewable carbon sources, via synthesis gas and methanol, to a mixture of hydrocarbons. The composition of this hydrocarbon mixture may range fro...

The review presents synthetic approaches to modern rhenium-based catalysts. Creation of an active center is considered as a process of obtaining a nanoparticle or a molecule, immobilized within a matrix of the substrate. Selective chemical routes to preparation of particles of rhenium alloys, rhenium oxides and the molecules of alkyltrioxorhenium, and their insertion into porous structure of ze...

This study focuses on 540 households originally living in public housing in high-poverty areas of Boston who participated in HUD’s Moving To Opportunity (MTO) demonstration. Participants were randomly assigned to one of three groups: Experimental – offered mobility counseling and a Section 8 subsidy valid in a 1990 Census tract with a poverty rate of less than 10 percent; Section 8 Comparison –...

A new myeloid cell line, MTO-94, was established from the bone marrow of a patient with myelodysplastic syndrome (MDS). MTO-94 cells matured in culture medium without the addition of growth factors, and yielded neutrophils with pseudo-Pelger Huët anomaly or hypersegmentation until 6 months. Ten months after the start of cell cultivation, MTO-94 consisted of myeloblasts. Surface phenotypes were ...

Abstract The relevance of a selection organic impurities for the initiation MTO process was quantified in kinetic model comprising 107 elementary steps with ab initio computed reaction barriers (MP2:DFT). This includes representative part autocatalytic olefin cycle as well direct mechanism starting from methanol through CO-mediated C–C bond formation. We find that effect different on evolution ...

Radial profiles of particle velocities were investigated in a 6.1m high methanol-to-olefins cold model experimental device using a TSI laser Doppler velocimeter. The effect of axial height on flow development was not obvious in fully developed region under the same operating condition. Superficial gas velocity and solid circulating rate had significant influence on particle velocity in the cent...

"> The effects of templating on the catalytic performance of SAPO-34 catalyst have been investigated in conversion of methanol to olefins. SAPO-34 <span style="font-size: 11pt; color: #000000; font-sty...

2,4,6-Triamino-1,3,5-triazine-1,3,5-trioxide (MTO) and 2,4,6-trinitro-1,3,5-triazine-1,3,5-trioxide (MTO3N) were suggested by Klapötke et al. as candidates for green high energy density materials (HEDM), but a successful synthesis has not yet been reported. In order to predict the properties of these systems, we used quantum mechanics (PBE flavor of density functional theory) to predict the mos...
