Abstract: Transition Metal Sulfides (TMS), such as molybdenum disulfide (MoS2), are the petroleum industry's “workhorse” catalysts for upgrading heavy petroleum feedstocks and removing sulfur, nitrogen and other pollutants from fuels. We have developed an improved synthesis technique to produce SLTMS catalysts, such as molybdenum disulfide, with potentially greater activity and specificity than those currently available. Applications for this technology include heavy feed upgrading, in-situ catalysis, bio-fuel conversion and coal liquefaction.

Abstract: A system for removing material from a surface includes a platform mounting a spinning water jet. A high pressure pump delivers water at a high pressure to the spin water jet.

The vacuum tank is provided with filters to screen removed materials from the waste water. The waste water then being returned to the fresh water tank for reuse.

Abstract: Novel methods for synthesizing wholly un-supported, high-flow catalytic membranes consisting of 100% crystalline ZSM-22 crystals with no binder phase, having sufficient porosity to allow high Weight Hourly Space Velocities of feedstock to pass through without generating back pressure. The ZSM-22 membranes perform favorably to existing bulk ZSM-22 catalysts (e.g., via 1-butene conversion and selectivity). The method of membrane synthesis, based on Vapor Phase Transport, allows free-standing, binder-less membranes to be fabricated in varied geometries and sizes so that membranes can be tailor-made for particular geometries applications. The ZSM-22 precursor gel may be consolidated into a semi-cohesive body prior to vapor phase crystallization, for example, by uniaxial pressing. These crystalline membranes may be modified by ion exchange, pore ion exchange, framework exchange, synthesis modification techniques to incorporate other elements into the framework, such as K, H, Mg, Zn, V, Ga, and Pt.

Abstract: A new crystalline maganese phosphate composition having an empirical formula: Mn3(PO4)4.2(H3NCH2CH2)3N.6(H2O). The compound was determined to crystallize in the trigonal space group P-3c1 with a=8.8706(4) Å, c=26.1580(2) Å, and V (volume)=1783 Å3. The structure consists of sheets of corner sharing Mn(II)O4 and PO4 tetrahedra with layers of (H3NCH2CH2)3N and water molecules in-between. The pronated (H3NCH2CH2)3N molecules provide charge balancing for the inorganic sheets. A network of hydrogen bonds between water molecules and the inorganic sheets holds the structure together.
