What catalysts are used in waste oil to diesel distillation process?

DOING has two different designs of waste oil to diesel distillation machines, which are used to recycle the waste engine motor oil/pyrolysis oil/crude oil to diesel, which can be used in diesel generators, boiler heating, ships, trucks and other machinery. One is the traditional type, using the liquid catalyst, the other is the newly designed type, which is independently developed by our engineer team, using the solid catalyst that you could buy from DOING directly.

Two types of DOING waste oil to diesel distillation machines

1. Traditional waste oil to diesel distillation machine-Liquid catalyst

The traditional design waste oil to diesel distillation machine needs to use acid and alkali as the catalyst. The acid is strong acid (Concentrated sulfuric acid). Alkali is normal NaOH. Clients can buy acid and alkali from the local market, so if the acid and alkali are easy to purchase at a reasonable price, this type will be a preferable choice.

For the traditional design waste oil to diesel distillation machine, firstly we need to heat the reactor to distillate the waste oil, after the oil gas goes through the cooling system, we can obtain the liquid oil, but this oil is not diesel yet. We need to use acid and alkali to wash the oil, remove the glue and wax, then you can get the diesel. This process will take about 8 hours, but the distillation and washing could be operated at the same time, they don’t affect each other.

2. New design waste oil to diesel distillation machine-Solid catalyst

The new design waste oil to diesel distillation machine uses the solid catalyst, which can be purchased from DOING directly, providing more convenience for our customers.

This solid catalyst is a special catalyst suitable for our waste oil to diesel distillation machine, which is developed by our technical engineers, which can exercise large molecular chains into small molecular chains while reducing sulfur content to a certain extent.

For new design waste oil to diesel distillation machine, the catalyst tower is on the distillation reactor directly. After the oil gas gets through the catalyst tower, it will turn to diesel oil gas directly, which can be cooled down to the liquid diesel oil directly, saving much operation work and is convenient to operate.

Despite the differences in used catalyst and operational processes, both types of waste oil to diesel distillation machines yield high-quality diesel from waste oil. And apart from the waste oil, our waste oil to diesel distillation machine can also recycle crude oil, tire/plastic pyrolysis oil, used lube/engine oil, liquid oil sludge, etc.

Projects of DOING waste oil to diesel distillation machines

DOING waste oil to diesel distillation machines have been operated successfully in many countries, such as Malaysia, Mexico, Ghana, Indonesia, China, etc. Throughout the collaboration process, our sales managers have provided attentive and dedicated services, assisting customers in selecting the most suitable waste oil to diesel distillation machines.
