The present invention addresses the problem of providing a heating furnace that sufficiently exhibits the microwave effect produced by microwave heating and allows economical heating taking advantage of the characteristics of each heating method. The provided microwave composite heating furnace (1) is equipped with:...

The invention discloses a continuous process for rapid baking of molded articles of any desired shape of cured composite materials by using electromagnetic radiations such as microwaves. This process produces products having the desired properties, with reduction in time and energy, and thereby improving economics o...

The method particularly relates to the preparation of sponge iron by rapid and direct reduction of iron ore lumps/fines/pellets in the reducing atmosphere without using any carbon containing reducing agent. Thus the method drastically reduces time required and energy consumed for the reduction of the iron ore to pro...

An eco-friendly, single step process for increasing the fusion temperature of coal ash and improving the combustion efficiency of coal, the process comprises of providing the coal in the form of lumps; placing the coal lumps in a microwave cavity/tunnel of the microwave system; exposing the coal lumps to electromagn...

A process for enhancing coal liquefaction yield from the petroleum crude-like extract so obtained from high ash containing coal by using electromagnetic energy such as microwaves followed by magnetic separation prior to subjecting coal to liquefaction process. The process causes selective and differential heating of...

A process for improving the quality and yield of middle distillates obtained by cracking the petro-bottom heavy stocks viz. Heavy Vacuum Gas Oil (HVGO) and the like, by treating the petro-bottom heavy stock with magnetization and electromagnetic radiations, and then cracking the so treated stock by means of any refi...

This invention relates to a microwave assisted green process for making steel i.e. pig iron or alloy steel from iron bearing materials such as iron ore or industrial waste materials containing iron. The process uses electromagnetic energy such as microwaves as a source of clean and efficient energy source to minimiz...
