Feb 08, 2009· Coal gasification is a process that converts coal into methane gas. If this reaction has a percent yield of 85%, how much methane can be obtained from 1250 grams of carbon? ... Chemistry help! Percentage yield? ... A sandpaper company uses silicon carbide, SiC, to make its product. Reacting silicon dioxide with graphite yielded ...
Refractories were evaluated for hotface liners for nonslagging, high btu coal gasifiers. Tests were conducted at high pressure and temperature conditions in the presence of steam, h2, CO, co2, and a mixture of these gases containing nh3 and h2s.
Abstract: The need to increase the cycle efficiency and reduce noise and NOx emissions from engines has promoted the development of ceramic matrix composites (CMC) such as silicon carbide (SiCSiC). Use of CMCs will lead to a significant improvement in fuel consumption and weight savings of up to 30% compared to Nibased super alloys.
The main idea of TyGRe consists in redirecting the gasification process towards the material recycling, by coupling a second thermal process, dedicated to the plasma synthesis of silicon carbide, to the preliminary waste tyres gasification.
Technical Report: Analysis of candidate silicon carbide recuperator materials exposed to industrial furnace environments Title: Analysis of candidate silicon carbide recuperator materials exposed to industrial furnace environments
TyGRe is a collaborative project and the partnership is composed of 9 partners; it is focused on the waste tyres recycling and promotes a thermal process mainly devoted to the production of ceramic materials.
In this frame the EUfunded project 'High added value materials from waste tyre gasification residues' (TYGRE) was designed to expand the material outputs of tyre recycling by providing a valuable material with a broad array of applications, silicon carbide (SiC).
