Magento 2 | Remove add to cart from catalog/category/view/
Add this code in below layout file :
app/design/frontend/Company_Name/Theme_Name/Magento_Catalog/layout/catalog_category_view.xml
<referenceBlock name="product.info.addtocart" remove="true" />
It may be useful for you.
I have looked into this using a Magento version 2.2.4
For me, the add to cart button dissapears after commenting some html in the template below:
app/design/frontend/<your_theme_namespace>/<your_theme_name>/Magento_Catalog/templates/product/list.phtml
line 78
you may comment the html starting with <div class="actions-primary"
(line 78 until line 104 (line closing this div)
