  The purpose of the present study was to test the effectiveness of a heterogeneous catalyst such as Nafion ion-exchange resin on the cellulose liquefaction process. The results obtained were compared with the bio-polyols obtained in a conventional way, using a homogeneous catalyst (sulfuric acid (VI)). Depending on the catalyst used and the temperature...

  W pracy przedstawiono wyniki badań obiegu ORC z prototypową pompą czerpakową czynnika roboczego HFE 7100 i elektrycznym przepływowym podgrzewaczem oleju termalnego w układzie ORC bez regeneracji. Z analizy wyników badań wynika, że w obiegu ORC bez regeneracji z zaworem rozprężnym (symulującym pracę mikroturbiny) osiągnięto przegrzanie par czynnika niskowrzącego HFE 7100. Uzyskano powtarzalność wyników badań wykonanych serii pomiarowych...

  - ENERGY - Year 2022

  The issues of the article are associated with the development of the renewable energy source (RES) sector in the world and in Poland. The subject is undoubtedly connected with the problem of the energy transformation taking place in most countries nowadays. Energy transformation processes are mainly associated with an increase in the share of energy production from RES and increased awareness of energy use by end consumers. This...
