Dingding Yao 12 month secondment to the University of Leeds, UK

Early career researcher Dingding Yao from Huazhong University of Science & Technology, China has spent the last 12 months at the University of Leeds, UK (November 2016-November 2017).  She undertook research into the recycling of waste plastics to produce hydrogen and carbon nanotubes. Dingding investigated the use of Ni-Fe catalysts for the catalytic pyrolysis of real-world waste plastics to produce hydrogen and high value carbon nanotubes, the work is to be published in the journal Applied Catalysis B-Environmental. She also worked on the pyrolysis-catalytic steam reforming of waste high density polyethylene for the production of hydrogen using different zeolite supported nickel catalysts. The work has also been submitted to Applied Catalysis B-Environmental for publication.  Further work on the influence of catalyst preparation methods on hydrogen production produced valuable insights into maximising hydrogen production from waste plastics.Dingding - Leeds

Julius Gane visits Hebei University

PhD researcher Julius Gane from the University of Leeds visited Hebei University, Tianjin, China for a one month secondment July-August 2017.  Julius was trained in the preparation of a novel MnTiO2 catalyst which can be used in his research into the upgrading of waste biomass pyrolysis oils to produce a gasoline like product and/or chemicals.  He also gained experience in how Hebei University researchers analyse the product oils using FTIR and GC/MS. Julius also gave a presentation of his PhD research to the research group at Hebei University.Julius Hebei

Kenneth Eboatu visits Tsinghua University

 

PhD researcher Kenneth Eboatu from the University of Leeds visited Tsinghua University, Beijing for a three month secondment from June 2nd to September 1st 2017.  Kenneth worked on the development of a new reactor system for the catalytic pyrolysis-gasification of waste urban wood.  He also gained knowledge in the preparation of a bifunctional catalyst for simultaneous syngas production with CO2 capture to enhance the concentration of hydrogen in the syngas.Kenneth

Dr Norbert Miskolczi presents FLEXI-PYROCAT research in India

Dr Norbert Miskolczi from the University of Pannonia in Hungary attended the 4th 3R International Scientific Conference on Material Cycles and Waste Management (4th 3RINCs) in New Delhi, India, 8 – 10 March 2017.  The conference is an annual International conference to promote the scientific waste management and spread the concept of 3R (Reduce, Reuse and Recycle) principles in our societies. It aims at bringing together academicians, scientists, engineers, entrepreneurs, govt. organizations, municipalities and other industrial organizations from all over the world under one umbrella to brainstorm on the recent developments in the fields of waste management and valorization of waste streams in an environment friendly manner. Dr Miskolczi presented a paper on research carried out under the FLEXI-PYROCAT project entitled “Two step pyrolysis of waste polymers: Catalyst efficiency in the second reactor” (authors; N. Miskolczi, J. Sója, M.A., Nahil, Williams P.T.

Hongman visits Hebei University of Technology

Miss Hongman Sun, from University of Hull, UK visited Hebei University of Technology, China from April-June 2017. She worked on multifunctional catalytic adsorbents with the aim of CO2 capture and utilisation. The mechanism and kinetic study of CO2 capture using commercial and synthesized CaO were also investigated. She carried out research work experimentally using a TGA analytical equipment and an in-situ DRIFTS reactor, etc.

Yeshui Zhang visits Tsinghua University

 

Yeshui - Tsinghua -01

Early career research Yeshui Zhang from the University of Leeds, UK visited Tsinghua University, Beijing, China from March –June 2017.  She worked on the development of novel nickel based catalysts with the aim of producing hydrogen from biomass. A further development was also incorporating calcium oxide into the nickel catalyst to capture carbon dioxide in-situ, thereby further increasing hydrogen yield. She developed a new reactor system using pyrolysis-catalysis and an on-line gas analysis system.

Outcomes of the workshop

Around 25 delegates from 17 institutes/companies (UK, China and Hungary) attended the workshop on pyrolysis and gasification of wastes and biomass in Hull. The delegates gave presentations covering fundamental catalysis, flexible process development, microwave pyrolysis, overview of industrial deployment in China, details of designing small-scale gasification system, molecular modelling and CFD modelling, and different applications of the products from pyrolysis/gasification of biomass and wastes. Ideas and knowledge have been intensively exchanged. Opportunities, challenges and solutions of gasification and pyrolysis have been discussed in three groups and presented. The results of group discussions are summarized as follows:

Workshop on pyrolysis and gasification of wastes and biomass

Workshop on Pyrolysis and Gasification of Wastes and Biomass

30 and 31 March 2017 – Hull

Supported by EU RISE and Newton Fund

Venue: Mercure Hull Royal Hotel (170 Ferensway, Hull HU1 3UF)

Background: Biomass and wastes are largely available. Converting them into useful products such as syngas, bio-oil and char is important to realize the values of these materials, and to improve the efficiency of the use of raw materials. In this work, we will focus on the advanced thermal-chemical conversion of biomass and wastes, including pyrolysis and gasification.

Delegates from universities and academics from different counties including China, UK and Hungary will present their recent work in the development of pyrolysis and gasification.
