Urea/SCR Technology for removing NOx from Diesel Engine

The advent of energy-efficient automotive diesel engine has significantly reduced its fuel consumption and CO2 emission to atmosphere in recent decades. From an environmental point of view, however, the emissions of atmospheric pollutants including nitrogen oxides (NOx) from the diesel engine become a primary concern, while CO and HCs can be readily oxidized by a diesel oxidation catalyst (DOC) commonly installed into diesel after-treatment system under lean operating condition. The abatement of NOx from the diesel engine exhaust is thus one of the critical issues for the commercial implementation of the modern energy-efficient diesel engine technology. 

Among promising NOx reduction technologies currently available, the LNT and the SCR technologies are the two leading ones despite their inherent shortcomings still remaining as important technical issues to be resolved. A practical advantage of the urea/SCR technology over the LNT rests on the fact that it does not require the use of a large amount of noble metals and complex engine controls which is the essential requirement for the LNT technology. The HC/SCR technology lags behind due primarily to its insufficient low-temperature activity and narrow operating temperature window on top of its poor tolerance toward H2O and SO2. 

The urea/SCR technology is undoubtedly one of the commercially proven, reliable and available technologies to meet the stringent worldwide environmental regulations including EURO VI and SULEV for reducing NOx emissions from diesel engine. The V2O5/TiO2 catalyst has been employed as the conventional SCR catalyst especially for the removal of NOx from stationary sources. However, V2O5/TiO2 may not be active in the diesel exhaust temperature ranging from 150~250 oC for light duty diesel engine to 200~350 oC for heavy duty one, and zeolite based-catalysts including ZSM5, SSZ13 and LTA have then been regarded as the promising urea/SCR catalyst to be directly applied to the diesel after-treatment system. In recent years, a number of efforts for further improving the low-temperature activity as well as the stability of the urea/SCR catalysts have been underway for their implementation to the next generation vehicles equipped with the advanced diesel engines.

In this presentation, the progress and challenges in the urea/SCR technology to remove NOx from diesel engine will be reviewed in the topics ranging from the underlying catalysis to the recent research trend and commercial applications. Included in the discussion will be the promoted SCR catalyst by the modification of catalyst support as well as the bimetallic catalyst systems aimed at improving the low temperature activity of the current urea/SCR catalysts and their catalytic characteristics. In addition, the local environment of active sites in CuSSZ13 and CuLTA, currently regarded as the promising commercial SCR catalyst, will be discussed by ESR and XANES studies in order to understand its strong thermal stability. Also presented will be the tolerance of zeolite-based SCR catalyst toward CO2, recently reported as a new deactivating precursor for the urea/SCR catalyst.

How to prepare Manuscript for APCATB

in view of Editors & Reviewers?

     Reviewing manuscript has now occupied a large share of scientists’ and engineers’ normal research efforts, since the number of submissions to journals has been dramatically increasing and the pressures on the speed of review and publication have become a key factor for the authors in determining the choice of journal.  Indeed, the wider range of leading journals is now available to authors and the journals even compete for the best papers. In this lecture, recent reviewing strategies will be described and discussed to reduce the number of poorly written and prepared manuscript to be checked by Reviewers and Editors, to clearly send a message to authors that they need to prepare well and to ultimately improve the quality of journal. These will involve the condition for good manuscript including scientific depth and novelty, ethical issue on plagiarism and publication procedure. Major components of journals will be also discussed together with organization of manuscript. 

The first part of the talk will discuss the general introduction of APCATB, mainly the role of Editors in three regions, Asian-Pacific, Europe and America and the recent journal performance. Indeed, this is one of the leading international journals, the 1st ranked in the field of catalysis, the 2nd ranked out of the 47 in the area of Environmental Engineering and it ranks first out of 134 journals in the field of Chemical Engineering. The journal has achieved very high impact factor of 11.698 in 2017 by ISI. In the second part, how to prepare high quality manuscript will be described in view of the structure & organization, length and novelty of the content. In the final part the ethical issue and use of the library programs available will be discussed for checking plagiarized sentences and phrases employed in the manuscript. 

One particular example concerning the reviewing procedures will be schematically illustrated for giving the authors an idea how the manuscript submitted to APCATB is handled. This procedure consists of three ways, submission, reviewing and decision. The reviewing procedure mainly includes two steps, prescreening step for confirming basic requirements and primary review process.
