Master Thesis Work:

Biomass to bio-fuels and bio-carbons by use of microwave enhanced pyrolysis

Background & objective
The value chain for lignin feedstock to bio-oils and bio-carbons is focused in this Master Thesis work.

The objective is to clarify/identify the technical and commercial potential to develop a business case, where kraft lignin or kraft lignin mixed with solid biomass (for example saw mill residues) is depolymerized to a biooil (for different purposes where one example is transportation fuel) and a bio-char (bio-carbon) by-product. Consequently, there is a need to identify different potential applications for both the bio-oil and the bio-char (bio-carbon). The depolymerization technology studied in this work is microwave-enhanced catalytic pyrolysis (MWDP) technology developed by Bionic BTL GmbH.

The bio-oil could have many different uses. The bio-oil could for example be hydrogenated to meet public standards for transportation fuel. The value chain summarized, and the best business concept proposed in more detail by a draft technology and commercialization roadmap for industrialization.

The commercial benefit of this technology is two product streams, i.e. bio-oil and char, targeting different market needs and customers. The technology is suitable for medium-sized, perhaps large, operations and will facilitate independent regional bio-economy in regions, potentially rural areas, with resources of lignin, saw dust and forestry residues. This has the potential to strengthen the local economy by local job creation and contribution on a national level to the “green conversion” of bio-oils and potentially transport fuels.

Challenges
• Cost structure for feedstocks, applications and creation of a complete business concept
• The technology which is in a quite early development phase
• Quality of products (bio-oil and bio-char), need for further purification/refining and production capacity
• Identification of funding & entrepreneurial forces
• Market interest – Market pull? Market push?
• A serious technology and commercialization roadmap for industrialization

Project Plan
The thesis work is suitable for one or two master students with excellent background in both technology and economy. The objective with this master student work is to clarify if it is possible to find a concept with good potential to form a business case in Värmland for a regional or national market. The work will focus use of available information which the master student/-s develop and refine. Limited experimental work can be justified in some cases.

Candidate
As a candidate for this Master Thesis work you should preferably like independent and creative work where you collect a lot of information by different contacts with the established actors in the field. A suitable background is industrial economy, chemistry, chemical technology and analytical chemistry. The work is planned for Q1 and Q2 2019.

Markets for & production of lignin-based polyurethanes (PU)

Background & objective
The company Enerlab in Canada has developed possible applications for lignin-based polyurethanes (PU) – 1) Spray Polyurethane Foam (SPF), 2) Polyisocyanurate Insulation Board (PIR) and 3) Structural Insulated Panel (SIP).

Upscaling of lignin-based polyesters

Background & objective
Lignin-based polyesters with a biodegradable property is an interesting future product developed by partners in the LignoCity Initiative. When a suitable production method is defined in detail and a business opportunity is secured we need to have larger scale production up running.

This master thesis work will focus the work usually made by consultants to create a first design of a production line. However, we want to take this opportunity to instead form a master thesis work, as a pre-project to a commercial installation. A production line is in this case planned to be built within the LignoCity Initiative in Bäckhammar. The objective is to design the layout of the production line, create and compare different alternatives, make cost calculations and predict the hurdles and advantages/drawbacks (make a SWOT analysis) for the different options to build such line. It is expected to select the best alternative and in more detail create a decision material from which it is possible to act on an investment.

The scale and more detailed specifications will be defined by the supervisors. The work includes collecting detailed information from many different sources. A lot of different aspects are to be taken into consideration from the foot-print of the upscaling to a detailed plan on how to put the different unit operations together into a production line.

Master thesis project:

Optimization of dyeing temperature on tissue paper

Background
Tissue especially napkins and tablecloths come in a lot of different colours and varieties. The dyeing operation is made in the stock preparation before the tissue is formed by the paper machine. The dyeing of tissue is controlled by charges i.e opposite charged particles attracts and identically charged repulses. The cellulose fibres and the dye molecules are both negatively charged which requires fixation. The fixation is made by positively charged chemicals which fastens the negative particles together. One of the many challenges to dye tissue is to eliminate bleeding, e.g the colour releases when you dry your mouth (the tissue gets wet). This could happen if the dye is not fastened by the fixation chemicals.

In the papermaking process freshwater sometimes is needed especially during colour changes. This requires heating of the water and this is made by steam. The demand and use of steam should be as low as possible due to environmental/cost reasons. Therefore, is it important to understand how the temperature of the water influences the dye- and chemical consumption and other water parameters such as pH and charge.

Project goal
The goal of the thesis is to optimize the dyeing process by finding the temperature that gives the lowest dye consumption and still fulfil specification regarding colour values and colour fastness.

Proposed thesis project
The thesis project will use dyes, chemicals (salt, alum and fixing agents) and pulp as materials. Lab dyed samples will be done at different temperatures. The samples will be tested regarding colour values and colour fastness. Process water and back water will be analysed regarding remaining colour, pH and charge. The work can be done at Rexcell Tissue & Airlaid AB.

For the applicant
The project is suitable for chemical engineering students writing their master thesis. Travel expenses and reimbursement are paid according to agreement.

The closed paper mill: An optimization of the water balance

Background
Papermaking requires water. A paper mill uses water as a medium and the water is taken from a nearby river/lake. After the papermaking process the water is purified in a treatment plant and then released back into the river/lake. This leads to a loss in energy due to that the water temperature is higher when released. With a changing climate (higher temperatures and droughts) a water intake restriction could be a possibility within a short future. The reduction of the water consumption could either be done by recycling the water or to reduce the amount of water delivered into the treatment plant. A reduction of process water to the treatment plant is of most interest and will lead to an energy, environmental and economic benefit. Therefore an investigation is needed to survey the paper mill’s water balance.

Project goal
The goal of the thesis is to propose an optimization of the water balance. This will include an investigation and survey of the existing water balance and proposing measures to reduce the water consumption.

Proposed thesis project
The work will be made at Rexcell Tissue & Airlaid AB. Conventional flow and temperature measurements will be taken. Necessary process data will be provided.

For the applicant
The project is suitable for chemical- or environmental & energy engineering students writing their master thesis. Travel expenses and reimbursement are paid according to agreement.
