A recognized technology expert known for synthetic and catalytic process

development for petrochemical and specialty chemical industry, Changkun has

more than 10 years research experience in industrial catalytic process, In-

depth knowledge of advanced catalyst characterizations and demonstrated

talent for project organization.

EDUCATION

2002 Ph.D., Changchun Institute of Applied Chemistry, CAS, China,

Polymer Chemistry

ethylene polymerization and immobilization"

1997 B.S., Suzhou University, Chemistry, PR China

Professional Experience

2012-present Principal Engineer, National Institute of Clean-and-Low-Coal

Energy, Beijing, China

2004-2011 Senior Scientist & Project Leader, Headwaters Technology

Innovation Group (HTIG), NJ, USA

2002-2004 Postdoctoral Fellow, Swiss federal Institute of Technology

(ETH), Zurich, Switzerland

Industrial Research

2012- Present: National Institute of Clean-and-Low-Coal Energy, Beijing,

China

Lead a 6-member team to develop the upgrading and refining process for coal

pyrolysis oil (alternative feedstock) at 50 thousand and1 million ton

oil/year, respectively. Total budget ?25M for 3 years. Six-sigma trained

(green belt).

2011- 2012: Albemarle Corporation, USA

Process development for new phosphorus flame retardant: changed the

synthesis process from previous high pressure process to low pressure

process with using high-boiling-point solvents, increased the product yield

for 8 percentages and decreased the process cost from $45 to $28 per

kilogram product with solvent residue lower than 200 ppm.

2004- 2011: Headwaters Technology Innovation Group, USA

Headwaters Technology Innovation Group (wholly-owned subsidiary of

Headwaters, NYSE: HW) is the developer of the innovative NxCat (Next

Generation Nanocatalyst TechnologyTM) which was successfully applied in

production process of specialty chemicals and petrochemicals.

1. Novel Supported Pt/Re Naphtha Reforming Catalyst, NxCat, for High

Liquid Recovery

From lab formulation to 6-ton reforming catalyst commercial

demonstration, Project Leader

o Applied the cutting-edge nanotechnology in developing next

generation naphtha reforming catalysts for high gasoline recovery;

applied the advanced characterization technologies to identify the

catalyst composition and fine surface structures; built the semi-

regenerative catalyst performance evaluation pilot plant;

investigated the reaction mechanism and catalyst kinetic model;

applied ASTM standards in gasoline product analysis and quality

control; extensively investigated scale-up conditions and

successfully scaled up catalyst from lab scale to tons per batch

without compromise on catalyst performance

o Six tons NxCat reforming catalyst was tested in refinery's reformer

for two years on 2000 Barrels/day; worked together with the client

to optimize the reaction conditions; helped the client to go through

the critical catalyst regeneration process.

Client confirmed that NxCat catalyst outperformed market catalyst with 1-

2% liquid yield and longer projected lifetime when RON ? 96.

2. Oil Soluble Catalytic MoSx Additives, HCAT, for Residue/ Heavy Oil

Upgrading in Fixed-Bed Reactor and Ebullated-Bed Reactor, Core team member

Declining reserves of lighter crude oil have resulted in an increasing

need to develop options to upgrade the heavy feed stocks. Fixed bed

reactors and ebullated bed reactors are the most used reactor systems in

commercial heavy/residue oil upgrading. However the high rate of coke

deposition and catalyst deactivation have resulted the high operation

costs.

o Applied colloid concept in design and preparation of oil soluble

MoSx; Applied modern characterization methods to define the

composition of active MoSx. Evaluated the oil soluble MoSx catalytic

additive in ebullated reactor and fixed bed reactor (packed with

commercial supported catalyst) for residue oil upgrading. Applied

ASTM standards in heavy oil and hydrocracking product analysis

(Sediment, HI, TI, distillation, MCR, viscosity etc.). Developed

technology sale strategy together with marketing department.

Headwaters, in conjunction with Neste Oil Corporation, announced

successful HCAT plant trial with heavy oil at 250 T /h, and oil soluble

MoSx at 50 Kg/h on Oct.6, 2010. HCAT application on fixed-bed reaction is

under negotiated with potential clients.

3. Catalysts for Polymers

1) Immobilized catalysts for ethylene trimerization for synthesis

of 1-hexene

Applied novel linking technology to immobilize tantalum chloride

catalysts on inorganic supports; the heterogeneous catalyst showed

the higher activity and selectivity compared to the homogeneous

catalyst for ethylene trimerization due to the reduced deactivation

through double active centers combination

2) High purity LED (light-emitting-diode) polymer

Developed hydrosoluble catalytic system for synthesis of LED

polymer through Suzuki coupling polymerization; Developed high

efficient solid scavengers for polymer purification; LED blue

polymer was received as molecule weight over 250,000 and metal

residue below 1ppm.

Postdoctoral Research

2002-2004: ETH Zurich, Switzerland

Investigated on ethylene polymerization mechanisms; developed

catalyst with novel ligands for ethylene polymerization

LEADERSHIP & PROJECT ORGANIZATION

As a project leader, one of Changkun's most significant achievements was

the successful 6-ton reforming catalyst commercial demonstration, which

was achieved by the team within 4 years in face of tremendous competition

from commercial catalyst suppliers. Changkun has led a project group that

consistently delivers results by aligning technology with business goals,

with substantial improvement in process standardization and research

efficiency.
