A compact Selective Catalytic Reduction (SCR) system comprising a system inlet, a gas flow system and a plurality of catalyst clusters is described. The system inlet is configured to utilize heat of the cleaned exhaust to vaporize a solution of a reductant, or a precursor of a reductant, and to mix the vaporized reductant with exhaust gas to form a mixed gas. The gas flow system is configured to provide the mixed gas from the system inlet to a plurality of catalyst clusters and to provide heat from the exhaust gas to assist in vaporization of the reductant/precursor and to assist in the conversion of the precursor to the reductant. The plurality of catalyst clusters comprise SCR and ASC catalysts but can also include filter functionality.

The present invention relates to processes for separating metals, and in particular for separating precious metals such as platinum and palladium, by solvent extraction. The present invention also provides novel solvent extraction mixtures useful in the processes of the present invention. The present inventors have found that by simultaneously employing different extraction mechanisms for the extraction of a plurality of different metals, a simple and convenient process for their separation can be achieved. In particular, the present inventors have found that the use of different extraction mechanisms for simultaneously extracting metals from an aqueous acidic phase into an organic phase enables the extracted metals to be separated by selective stripping from the organic phase using simple and mild conditions. This process is particularly advantageous as it permits two or more metals to be separated following a single solvent extraction step, because of the ability to selectively strip the metals from the organic phase.

The catalyst module (2) is designed for use in an emission control system of a stationary incinerator. It comprises a stack frame (4), into which several mounting units (6) are inserted strung together. The mounting units (6) have a peripheral side wall (22) as well as several partitions (24a, 24b), which are entangled with one another and form a lattice with a plurality of mounting shafts (26), in which in each case one catalyst (10) is inserted. The catalysts (10) are pressed into position preferably with the interposition of an elastic fitting element (30).

Articles comprising a catalyst film comprising VOx, MoO3 or WO3, and TiO2 deposited on a substrate are disclosed. The articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases. Methods for producing such articles deposit a catalyst film on the substrate to form a coated substrate, which is then calcined. When used in an SCR process, the coated articles have enhanced activity for NOx conversion, reduced activity for SOx conversion, or both. Light-weight, coated articles having high catalyst loads can be fabricated at the same or reduced dimensions when compared with laminated articles, and increased kNOx/kSOx ratios are available even from coated articles having relatively thin catalyst films. The articles should have particular value for power plant operations, where coal and high-sulfur fuels are commonly used and controlling sulfur trioxide generation is critical.

The present invention relates to a process for removing carbon dioxide from a mixture of gases, and to a process for reducing the partial pressure of carbon dioxide in an enclosed space. The processes of the present invention employ a carbon dioxide adsorbent comprising benzyl amine moieties immobilised on a solid support. The process comprises regenerating the adsorbent by heating to a temperature in the range from 40C to 75C.

Objectives The H-CCAT project designs, upscales and shapes hybrid catalysts for the C-H functionalization of aromatic compounds. These solid catalysts will possess better recoverability, higher turnover numbers and better selectivity than current homogeneous catalysts for these reactions. The solid catalysts are applied at demonstration scale in the step-economical production of arylated or alkenylated aromatics, yielding motifs of active pharmaceutical ingredients. Methodology We will design heterogeneous hybrid catalysts featuring deactivation-resistant active sites, based on N-heterocyclic carbenes (NHCs) or diimine ligands and active metal ions. Via efficient, one-step protocols based on self-assembly, these sites will be embedded in robust porous hybrid materials like hybrid silica or metal-organic frameworks. Deactivation or metal aggregation will be prevented by site isolation or by efficient metal reoxidation (for the oxidative alkenylations). Metal leaching is precluded by using strong bonds between metals and embedded ligands like NHCs. Flow protocols will be designed to maximize the turnover numbers. Catalyst synthesis will be scaled up to kg scale, using efficient one-step protocols, minimizing use of solvents or waste formation. Soft shaping methods, e.g. spray drying, will preserve porosity and activity of the hybrid solids. A demonstration is conducted at minipilot scale at the J&J site (Belgium), allowing LCA analysis, techno-economic assessment and elaboration of the business plan. Relevance to work program The catalysts feature new, deactivation resistant active sites; their TOF/TON is maximized by an appropriate porous structure which even can be swelling. Catalysts are produced using innovative one-step protocols to form porous hybrid catalysts as powders or even immediately as shaped objects. The molecules targeted have strong biological and pharmaceutical relevance; they target diseases like influenza, cancer or HIV (case study: Rilpivirine).

ES-Cat will use directed evolution as a tool to reproduce Natures remarkable ability to generate molecular machines - in particular enzymes that perform at levels near perfection. Instead of seeing rational and combinatorial approaches as alternatives, we combine them in this network to achieve a smarter and more efficient exploration of protein sequence space. By harnessing the forces of Darwinian evolution and design in the laboratory we want to (i) screen large and diverse libraries for proteins with improved and useful functions, (ii) optimize existing proteins for applications in medicine or biotechnology and (iii) provide a better understanding of how existing enzymes evolved and how enzyme mechanisms can be manipulated. This Network brings together leading academic and industrial groups with diverse and complementary skills. The range of methodologies represented in ES-Cat allows an integrated approach combining in silico structural and sequence analysis with experimental high-throughput screening selection methods (phage-, ribozyme and SNAP display, robotic liquid handling, lab-on-a-chip/microfluidics) with subsequent systematic kinetic and biophysical analysis. This integration of methods and disciplines will improve the likelihood of success of directed evolution campaigns, shorten biocatalyst development times, and make protein engineering applicable to a wider range of industrial targets. It will also train the next generation of creative researchers ready to fill roles in tailoring enzymes and other proteins for industrial application in synthetic biology efforts to move towards a bio-based economy, rivaling advances that are being made in the US and allowing the EU economy to harvest its evident socio-economic benefits.
